You need a valid hardware reset configuration word (HRCW) for the processor to come up enough to flash (the CPU PLL clock settings are controlled by the HRCW). The HRCW lives in the first 32 bytes of flash and gets read when power is applied: if you erase all of flash, you will erase your HRCW. This is OK as long as you reprogram it before you cycle power. Ooops, too late ;-) You should have a "RSTCONF*" (reset configuration) jumper/switch connected to the RSTCONF on the processor. When asserted (low), this causes the processor to use a default HRCW which will allow you to reprogram the desired HRCW in flash. Since you have a Mot board, it may have a BCSR-supplied HRCW, check your documentation. The bottom line is, you need a reasonable HRCW (in particular a reasonable clock setting in the HRCW) in order for the processor to be operational enough for JTAG to work. gvb > -----Original Message----- > From: u-boot-users-admin(a)lists.sourceforge.net > [mailto:u-boot-users-admin@lists.sourceforge.net] On Behalf > Of Santoso, Yusdi > Sent: Tuesday, October 19, 2004 12:47 AM > To: u-boot-users(a)lists.sourceforge.net > Subject: [U-Boot-Users] BDI2000 flashing problem > > Hi all, > > I have a problem using BDI2000 to flash u-boot into my board. > I had it working yesterday, but this morning it just refused to work. > Does the BDI flashing require some boot loader code to be > already available in the flash? > > Thanks, > > > Yusdi ****************************************** The information contained in, or attached to, this e-mail, may contain confidential information and is intended solely for the use of the individual or entity to whom they are addressed and may be subject to legal privilege.

[U-Boot-Users] memory map
by jhoney jhoney 19 Oct '04

19 Oct '04

Hello All, I am new to U-boot. I have one board with u-boot and inturn passes control to Linux . I got a question like whatever the memory map initialization done by the u-boot will be carried out to the linux up on boot up. For example , in my case u-boot configures pci at E0000000 and whatever the data is sent to the address E0000000 is passed to the PCI interface. Up on booting the linux, whether the same address will be mapped to the pci or Linux does the re-initialization again. Thanks in advance Regards Jhoney

[U-Boot-Users] BDI2000 flashing problem
by Santoso, Yusdi 19 Oct '04

Hi all, I have a problem using BDI2000 to flash u-boot into my board. I had it working yesterday, but this morning it just refused to work. Does the BDI flashing require some boot loader code to be already available in the flash? Thanks, Yusdi The BDI telnet log: // Board: Motorola Hidden Dragon, quite similar to Sandpoint // Processor: MPC8241 // Memory: start = 0x00000000 // size = 32 MB // Flash: start = 0xff800000 // size = 2 MB = 1 bank x 16 bits x 1 M // Initialization message - TARGET: waiting for target Vcc - TARGET: waiting for target Vcc - TARGET: processing power-up delay - TARGET: processing user reset request - BDI asserts HRESET - Reset JTAG controller passed - Bypass check: 0x000000001 => 0x00FFFFFF - JTAG exists check failed - Remove HRESET and try again - Bypass check: 0x000000001 => 0x00000001 - JTAG exists check passed - COP status is 0x01 - Check running state passed - BDI scans COP freeze command - BDI removes HRESET - Target PVR is 0x80811014 - COP status is 0x05 - Check stopped state passed - Check LSRL length passed - BDI resumes program execution - COP status is 0x01 - Waiting for target stop failed // Flash is still blank (0xffff) - TARGET: Break at boot vector failed, freeze forced - TARGET: Target PVR is 0x80811014 - TARGET: resetting target passed - TARGET: processing target startup .... - TARGET: processing target startup passed BDI>info Target CPU : MPC82xx (G2H4) Target state : debug mode Debug entry cause : COP freeze (startup) // The reset vector is at 0xfff00100, seems like the processor has executed few bytes // but not sure why stop here.

RE: [U-Boot-Users] USB Console
by Woodruff, Richard 19 Oct '04

19 Oct '04

Here is the write up we used to do this for USB serial with a 1510. You should disregard the 'setslink' comments below. Someone at TI originally had it working in a u-boot variant here. Wolfgang implemented a slightly different version for the SX1. Hope this helps more than confuses. Regards, Richard W. ---------------------------------------------- Software configuration ====================== Host side --------- On the PC host side, you need to configure the kernel to support USB serial devices. Assuming you are using "make menuconfig" or "make xconfig", go to "USB Support" section and enable the options as follows ("M" means "enable as a loadable module"): If, and only if, "Support for USB is set to <N>, then: - Support for USB <M> Also enable the /proc filesystem for USB: - Preliminary USB device filesystem <Y> Then choose a driver for your USB controller and enable it as module, i.e. exactly one of the following: - UHCI (Intel PIIX4, VIA, ...) support <M> or - OHCI (Compaq, iMacs, OPTi, SiS, ALi, ...) support <M> Then go to "USB Serial Converter support" subsection and enable: - USB Serial Converter support <M> - USB Generic Serial Driver <Y> Next, recompile the kernel and install kernel itself and modules as usual. NOTE: You may want to replace your existing copy of usbserial.c with the version from cvs. This version is fixed to prevent a common segfault. You can find the updated source file at PET/src/os/linux/drivers/usb/serial/usbserial.c. After this, make sure you have the following modules installed: * usbcore.o - the core of host USB subsystem (if "USB Support" above was <Y>, this isn't needed) * [host controller driver].o - driver for the host USB controller * usbserial.o - host-side serial function driver For example, if you are using UHCI host controller and the kernel modules are placed in their default locations, type: find /lib/modules/`uname -r`/kernel/drivers/usb -type f at the shell prompt. You should see something like this: /lib/modules/2.4.19/kernel/drivers/usb/usb-uhci.o /lib/modules/2.4.19/kernel/drivers/usb/serial/usbserial.o If this is true, host configuration is completed. Kermit ------ If you don't already have kermit installed on your linux host machine, do the following: Update your cvs PET/src/os/tools/ directory. Go into PET/src/os/tools/ckermit and run 'make linux' and 'make install'. Now, when you type 'which kermit' you should see '/usr/local/bin/kermit'. This is the program that minicom will run when doing uploads to your device. Copy the file u-boot.kermrc from the PET/src/os/tools/ckermit directory into your home directory. RENAME THIS FILE TO .kermrc. This file contains important setup commands to initialize kermit. Minicom ------- To communicate with the TTY client, you'll need to create a minicom configuration which uses /dev/ttyUSB0. Run minicom, as root, with the -s option and do the following: - Type <Control-A> O (letter o) to get into the configuration menu. - Choose "Filenames and paths". Change the value of "E - Kermit program" to the location of kermit on your host system. 'which kermit' will give you the correct path to use here. Press enter to go back to the previous screen. - Choose "File transfer protocols". You shuld have 2 entries for kermit. Modify the first (has U in the U/D column) so that the "Program" column has the following value: "kermit -i -l %f -s". - Choose "Serial Port Setup". Now change the value of "A - Serial Device" to be /dev/ttyUSB0. - Now press enter to go back to the previous screen and select "Save setup as...". Save this setup as usb. - Exit from minicom. OMAP1510 client side -------------------- On the 1510 client side, you need to configure the kernel to get the latest version of u-boot out of cvs. Build u-boot as usual. Make sure you have a USB "A to mini-B" cable. That's a normal sized host connector on one end and a mini-sized client connector on the other end. Client end goes into the device. Running ======= Setting up TTY-over-USB connectivity --------------------------------------- On the host side, you need to load kernel modules, exactly in the following order, by typing: insmod [host controller driver] insmod usbserial vendor=0x0451 product=0xe003 Then re-plug the USB cable and examine log files (usually somewhere in /var/log, check your /etc/syslog.conf) on the host system. You should see something like the following (date and host name fields are skipped): kernel: hub.c: USB new device connect on bus1/1, assigned device number 9 kernel: usb.c: kmalloc IF c0f74ec0, numif 1 kernel: usb.c: new device strings: Mfr=1, Product=2, SerialNumber=0 kernel: usb.c: USB device number 9 default language ID 0x4e3e kernel: Manufacturer: Texas Instruments kernel: Product: TI PET Bootloader kernel: usbserial.c: Generic converter detected kernel: usbserial.c: Generic converter now attached to ttyUSB0 (or usb/tts/0 for devfs) kernel: usb.c: serial driver claimed interface c0f74ec0 Now you can run minicom with your usb configuration: 'minicom usb'. You should see the first few lines of your u-boot console. Downloading to the device ------------------------- With the modules loaded on the host machine as explained above, set up u-boot for USB downloads using kermit. - At the u-boot prompt type 'setslink usbtty'. This will select the usbtty device as your download link. - Now type 'loadb'. This will pause, waiting for data to be sent from the host. - Now type <Control-A> S in minicom to bring up the "Upload" menu. Choose "kermit" as the upload protocol. Select the file you wish to transfer and then choose "Okay" (notice menu buttons at bottom of screen, you can use the arrow keys to move between these). You should see a kermit upload progress window. When the transfer has completed, u-boot should display a download summary showing the number of bytes transferred. If you don't want to use minicom for a USB TTY device, but still want to be able to use the USB cable to upload files to the device, you can run kermit by hand. - From a serial minicom console, run 'setslink usbtty' to ensure that u-boot uses USB for downloads. - Now set your device in kermit download mode by typing 'loadb'. - Make sure that your USB cable is connected and then run 'kermit -i -l /dev/ttyUSB0 -s fileName' where fileName is the file that you wish to upload to the device. > -----Original Message----- > From: u-boot-users-admin(a)lists.sourceforge.net [mailto:u-boot-users- > admin(a)lists.sourceforge.net] On Behalf Of Jayme Hero > Sent: Monday, October 18, 2004 2:54 PM > To: u-boot-users(a)lists.sourceforge.net > Subject: [U-Boot-Users] USB Console > > Hi > > I am using U-Boot and want to use the USB console.

Hi I am using U-Boot and want to use the USB console. I am have an OMAP1510 and am connecting it as a device to a PC running Suse 9. Linux recognizes that something has been connected to the USB port, but it loads the acm diver, starts a modem configuration utility, and I think it sets the device and /dev/acm0. I cannot connect to this with kermit. How do I need to setup my computer to get a console over USB? Thanks for any help jeh

[U-Boot-Users] PATCH SoC AT91RM9200
by Steven Scholz 18 Oct '04

18 Oct '04

Hi there, since Atmels AT91RM9200 is an System on a chip based on around an ARM920T core I moved the relevant code into cpu/arm920t/at91rm9200 so it follows the new SoC concept. Due to the size of the patch I'll send it directly to Wolfgang. Thanks. CHANGELOG: * Patch by Steven Scholz, 18 Oct 2004: - Move at91rm9200 relevant code into cpu/arm920t/at91rm9200 - Fix linker scripts for AT91RM9200 based boards - If $SOC is passed to ./mkconfig create include/asm-$ARCH/arch-$SOC instead of include/asm-$ARCH/arch-$CPU, so it looks more like the linux kernel tree - Move files out of include/asm-arm/arch-arm920t into appropriate include/asm-arm/arch-$SOC directories Thanks! -- Steven Scholz imc Measurement & Control

[U-Boot-Users] U-boot compile issue with GCC 3.4

We are users of a Logic PD LH7A400 board. Currently using a Debian host we managed to make ourselves a GCC for arm (Version 3.4). Now when we compile U-Boot 1.1.1 patched for LH7A400 we get the following errors. If anyone can throw some light on them, we would appreciate that. cc1: error: invalid option `short-load-bytes' cc1: error: invalid option `short-load-bytes' make[1]: *** [.depend] Error 1 make[1]: Leaving directory `/home/devraj Dump from GCC 3.4 for arm --version devraj@raphaelle:~/lpd7a400/uboot/u-boot-1.1.1$ arm-linux-gcc --version arm-linux-gcc (GCC) 3.4.1 (Debian 3.4.1-1) Copyright (C) 2004 Free Software Foundation, Inc.

[U-Boot-Users] Those hello_world compilation problems
by Jon Loeliger 17 Oct '04

17 Oct '04

Folks, I did some digging on our toolchain here on our new Yellowdog 4.0 installed machines. They have a 3.3.2 compiler on them by default, apparently. As someone else discerned, that cause an issue with the dummy() function being static in the stubs.o file for the examples directory. I've found that all appears to be better if the test in the example/stubs.c file is changed from: #if GCC_VERSION < 3004 to #if GCC_VERSION < 3003 (BTW, the GCC_VERSION symbol, google revealed, comes from ansidecl.h. Oh yeah.) I'm not sure of the generality of this fix, so I am reluctant to submit a direct patch for it. Perhaps someone more familiar with the details of either the YDL 4.0 or GCC 3.3 vs 3.4 releases can speak authoritatively on this issue. HTH, jdl

[U-Boot-Users] TFTP configuration Vs gdb response time !
by ravi.aloor＠wipro.com 16 Oct '04

16 Oct '04

Hi All, A brief explanation about my working environment: - ARM11 based target board, having its own IP address - My PC running on RedHat Linux-8.0, having its own IP address, as host machine with only CLI and no GUI-XWindows - BDI2000, having its own IP address - PC and BDI2000 are connected to the network independently - U-boot is already available on target board in the flash memory - Firmware is already available on BDI2000 - BDI2000 is connected to the target board through - Using gdb-6.1 configured with --target=arm-linux - Documents referring: README, DULG, bdiGDB maual - I am not using ELDK as explained in DLUG - About our network: I am not sure I want to debug u-boot and also kernel with good response from gdb. The following are my doubts. 1. I have TFTP server already configured on our network. But the response time of gdb is too bad, while debugging. I will not come to know what is happening also. So I thought I will make my PC only as TFTP server to get faster response from gdb. This idea is right / wrong ? If my idea is wrong, what could be the possible reason for gdb's slow response ... ? My PC has PIII processor and 128MB RAM. Do you suggest to increase RAM on my PC ? This anyway I planning to do. Does the response time of gdb depend on network speed also ? 2. In gdbBDI manual, the explanation is given by directly connecting the target board to the host machine with Ethernet cable. Serial cable connection is only for initial configuration of BDI. But in my case, both the target board and my PC are connected separately to the network. Is it ok ? 3. I started to make my PC itself as TFTP server. I followed DLUG document for this purpose and I configured BDI accordingly as shown below: [root@localhost BDISetUp]# ./bdisetup -c -p/dev/ttyS0 -b115 -i192.168.226.-h192.168.226.168 -m255.255.255.128 -g192.168.226.129 -fBDI-new.cfg Connecting to BDI loader Writing network configuration Configuration passed [root@localhost BDISetUp]# ./bdisetup -v -p/dev/ttyS0 -b115 -s BDI Type : BDI2000 Rev.C (SN: 95590442) Loader : V1.05 Firmware : V0.99 bdiGDB for ARM11 Logic : V1.06 ARM MAC : 00-0c-01-95-59-04 IP Addr : 192.168.226.159 Subnet : 255.255.255.128 Gateway : 192.168.226.129 Host IP : 192.168.226.168 Config : BDI-new.cfg 4. Now I already have BDI-new.cfg file in my /tftpboot/ directory on my PC. I pinged BDI. Response is OK. Then I made 'telnet' to BDI. The following is the brief response. VERIFY [<offset>] [<file> [<format>]] verify a program file to target memory PROG [<offset>] [<file> [<format>]] program flash memory <format> : SREC, BIN, AOUT, ELF or COFF ERASE [<address> [<mode>]] erase a flash memory sector, chip or block <mode> : CHIP, BLOCK or SECTOR (default is sector) ERASE <addr> <step> <count> erase multiple flash sectors UNLOCK <addr> <step> <count> unlock multiple flash sectors FLASH <type> <size> <bus> change flash configuration FENA <addr> <size> enable autoamtic programming to flash memory FDIS disable autoamtic programming to flash memory DELAY <ms> delay for a number of milliseconds SELECT <core> change the current core len : the number of bits 1..256 bx : a data byte, two hex digits HOST <ip> change IP address of program file host PROMPT <string> defines a new prompt string CONFIG display or update BDI configuration CONFIG <file> [<hostIP> [<bdiIP> [<gateway> [<mask>]]]] HELP display command list QUIT terminate the Telnet session # CONFIG: cannot open BDI-new.cfg # CONFIG: cannot open BDI-new.cfg Core#0> Means, it is not getting my BDI-new.cfg file even though the file is in /tftpboot/ directory on my PC while my PC is working as TFTP server.

[U-Boot-Users] u-boot for atmel at91rm9200 QI-002 board
by Shakthi Kannan 16 Oct '04

16 Oct '04

Greetings! We have an atmel at91rm9200 qi-002 board from a vendor having vendor's monitor image, ramdisk image, and kernel image 2.4.19-rmk7 in flash. I tried to use u-boot 1.1.1 with the configuration of at91rm2900dk_config: $cd u-boot-1.1.1 $make CROSS_COMPILE=arm-linux- at91rm2900dk_config $make CROSS_COMPILE=arm-linux- all (Using cross-toolchain 2.95.3 from http://ftp.arm.linux.org.uk/pub/armlinux/toolchain/) This generated the requried u-boot, u-boot.bin, u-boot.srec files. I tried to run it from the target ARM SDRAM, but, nothing happened. No output at all. Do I have to rewrite the entire configuration files for the new target board for u-boot to work on the new board? Any suggestions? Thanks, Shaks _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com

[U-Boot-Users] Doubts about usage of BDI2000 !

Hi, I am new to u-boot. I have few doubts. A brief explanation about my working environment: - ARM11 based target board, having its own IP address - PC running on RedHat Linux-8.0, having its own IP address - BDI2000, having its own IP address - PC and BDI2000 are connected to the network (IP address for BDI2000 is 192.168.226.159) - U-boot is already available on target board in the flash memory - Firmware is already available on BDI2000 - BDI2000 is connected to the target board through - Using gdb-6.1 configured with --target=arm-linux The following are my doubts: 1. I want to debug u-boot. So to start debugging u-boot, Do I need to use bare target board that does not contain u-boot already ? 2. I could not start debugging u-boot. So I started debugging kernel with the target board that already contains u-boot.

I am not sure that I understand how to pick up the bootargs variables in Linux (ocotea) PPC. I looked at codes of different machine but I do not know which one fit fro my 440GX based-machine. I am still looking into these bd_t and bi_record structure to see if I can find the answer. Any help welcome?

[U-Boot-Users] Is pci_hose_scan() necessary?
by Prathima_Kolar 14 Oct '04

14 Oct '04

Hello All, We are in the process of making custom PCI Mezzanine Card (PMC) based on the mpc8266. It will be connected to a carrier board using PMC connectors. It is to be configured as a master waiting for PCI interrupts from the carrier board, also a master. I have the job of customizing u-boot for the board, and I am currently stuck in the initialization + configuration of the PCI interface. My question is: What is the significance of pci_hose_scan() in the particular case of our board? At first sight, it seems to be the carrrier board's job to do the pci_hose_scan, not mine. But some research on the net showed that pci_hose_scan is a necessary part of PCI initialization, whether the board is a master or a slave. So should I include it in my customized u-boot, or should I comment it out?

[U-Boot-Users] Resolved -- Problems accessing flash on OMAP 1510 Innovator
by Stephen Johnson 14 Oct '04

14 Oct '04

After studying code in rrload and doing some googling, I tried an experiment and it worked. In the file board/omap1510inn/flash.c I changed the function get_flash_size() so that it now contains the following code: /* Write auto select command: read Manufacturer ID */ // addr[0x5555] = (FPW) 0x00AA00AA; // addr[0x2AAA] = (FPW) 0x00550055; // addr[0x5555] = (FPW) 0x00900090; addr[0] = (FPW) 0x00900090; In other words I got rid of three lines of code and added my own. I can now access -- both read and write -- the flash. My only concern is what have I broken by this change! But for now I'm happy. Thanks for everyone's help. Steve

I should just have you double check that you're checking the DIP switches on the processor-module of the Innovator and not the large break-out-board where the modules are laid out in a non-stacked way. I banged my head against a wall for about a week when I was adjusting the wrong switches one time. I partly attributed it to poor documentation of the BoB by TI and partly user error. -Michael Bendzick

[U-Boot-Users] Problems accessing flash on OMAP 1510 Innovator
by Stephen Johnson 13 Oct '04

I'm trying to install and run u-boot in an OMAP Innovator 1510 board. I've downloaded the CVS version of u-boot, configured it with "make omap1510inn_config" and compiled it with no problem. It's installed in the flash and runs. The problem is the flash can't be found -- on startup up Flash: 0 kB is reported and I can't save anything. Other flash accesses are similar. Sample output follows where I've powered on the board, run "flinfo", and tried to do a "saveenv". Any help would be appreciated.

my u-boot version is 1.1.1, and the cpu is 440gx.

Wolfgang, Thanks for the response. I will resubmit with necessary changes. A little info regarding point [2]: > No. I reject this. [2] Please do not pollute the Makefile and MAKEALL > (oops, you even forgot to update this one!) with so many different > build targets which differ only in the available RAM size of the > target. There is existing code (in common/memsize.c) to atomatically > detect the available size, so please fix your code and auto-adjust as > needed. I had code to autodetect the ram working but I removed it since it required changes to several files relating to how the DRAM config is handled (printed, passed to kernel, etc). For configurations with more than 32MB of DRAM the layout is not contiguous, ie. more than one bank is required. Since the number of DRAM banks is #defined there is no way to adjust this at runtime. The result is having an extra bank of zero size configured for boards with <= 32MB DRAM. This gives the wrong impression...that there are more DRAM banks but for some reason one is zero size (ie. something is wrong). I've since booted a kernel with the above setup and it seems to deal with the zero size bank fine so I guess this isn't a problem from the operation point of view. It would be nice if either: 1) the number of DRAM banks was configurable at runtime. 2) leave the number of DRAM banks #defined (as max. banks) and simply add checks for zero size in the config print, kernel atag, etc. handling to skip such banks. -- Paul Ruhland

It is hard to say exactly. Perhaps your flash is locked. Many version of the newer OMAP development platforms come with their flash locked. The flash.c code in those has been updated to issue an unlock first. Seems like the innovator may have had two kinds of flash also....it also had a feature where sram could be mapped to 0 instead of flash. I'd first check your jumper settings, then second pinch some code from one of the other omap ports to unlock flash...(that is after making sure its even there and showing up correctly with an debugger).

440gx cpu and ocotea board. when i reset the board, the board cannot work well. i check the u-boot.bin with hexdump -------------------------------------- hexdump -s 0x7fffc u-boot.bin 007fffc ff4b 04f0 -------------------------------------- but after the board boots md.l 0xfffffffc 1 00220000 ------------------------------------- the result is error, so the board cannot reset. I set the _start_440 relative address, it can reset ok. it seems as if the bootrom mapping is error.

sorry,,, this time plain text i ported uboot-1.0.0 with success on my board , it works fine ( i think ) i can download kernel image and no problem with mtest but when i enter "bootm" "Uncompressing kernel...OK" and no more message but i tested it with a reference board , uboot-1.0.0 and kernel 2.4.4 from (www.denx.de) on reference board it wokrs find ( i searched mailing-list and found "Uncompress...." problem because of HZ issue or bd_t type error i think that is not my case ) i have no reference board circuit but i tried to designe my board with same momery ( type and size) , just they differs in CPU version ( reference is A.1 1K22A-XC , my board is C.2 6K23A could it cause a problem ? ) i use the same uboot in both boards i have no idea what is wrong ? SW or HW ? give me some ideas or hints thanks in advance

[U-Boot-Users] linking u-boot for mips little endian w/ hardhat tools.
by C Michael Sundius 12 Oct '04

12 Oct '04

Hi, I am trying to port u-boot to a system w/ a mips 4kc little endian processor. in looking at other cpu/boards to use as a starting point/template, I chose the tb0229 board as it looked to also be a 4kc little endian cpu. when I build, I get the an undefined reference to _GLOBAL_OFFSET_TABLE_. I did some fiddling aroud, and comparing to linker command files for other boards and I found that the line: OUTPUT_FORMAT("elf32-tradlittlemips", "elf32-tradlittlemips",\ "elf32-tradlittlemips") if changed to: OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips", "elf32-tradbigmips") will allow me to compile and link fine... my question is then: 1) what does this really do? 2) if I'm using a little endian cpu, do I really need it set to elf32-tradlittlemips? 3) if so how do I solve my problem? 4) if not why? one more note the compiler/toolchain that I'm using is from montavista, the -v option displays the following: ====================================== mips_fp_le-gcc -v Reading specs from /opt/hardhat/devkit/mips/fp_le/lib/gcc-lib/ mipsel-hardhat-linux/3.2.1/specs Configured with: ../configure --host=i686-pc-linux-gnu --target=mipsel-hardhat-linux --prefix=/opt/hardhat/devkit/mips/fp_le --exec-prefix=/opt/hardhat/devkit/mips/fp_le --bindir=/opt/hardhat/devkit/ mips/fp_le/bin --sbindir=/opt/hardhat/devkit/mips/fp_le/sbin --sysconfdir=/ opt/hardhat/devkit/mips/fp_le/etc --datadir=/opt/hardhat/devkit/mips/fp_le/ share --includedir=/opt/hardhat/devkit/mips/fp_le/include --libdir=/opt/ hardhat/devkit/mips/fp_le/lib --libexecdir=/opt/hardhat/devkit/mips/fp_le/ libexec --localstatedir=/opt/hardhat/devkit/mips/fp_le/var --sharedstatedir=/ opt/hardhat/devkit/mips/fp_le/share --mandir=/opt/hardhat/devkit/mips/fp_le/ man --infodir=/opt/hardhat/devkit/mips/fp_le/info --program-transform-name=s,^,mips_fp_le-, --enable-cross --with-gxx-include-dir=${prefix}/mipsel-hardhat-linux/include/g++-v3 --enable-shared --enable-languages=c,c++ --enable-threads=posix --enable-__cxa_atexit --disable-multilib Thread model: posix gcc version 3.2.1 20020930 (MontaVista) ======================================= thanks for any help you can offer...(sorry this is maybe more of a tool related question, but monta vista has not been much help as of yet).

This question is not related to U-boot(reset) in perticular but the 440GX. I did not get a response that answer my question from IBM or AMCC. In the 440GX PCI registers at offset 0xd4, there is the power managemement register. if you write 3 then 0 it should reset the 440GX. However, once Linux or U-boot are booted, this does not work anymore. I have not found what prevent the reset. If you have any clue, please let me know.

[U-Boot-Users] [PATCH] Running from SDRAM Detection on omap1510inn
by Michael Bendzick 11 Oct '04

11 Oct '04

Included is a patch that improves the detection scheme in platform.S that the omap1510inn build uses to determine whether or not it is running from SDRAM. The result of the detection is used to determine if the SDRAM configuration registers are safe to change. The previous implementation only made a distinction between running from Flash at 0x0 or SDRAM at 0x10000000. This patch allows U-Boot to run from internal SRAM at 0x20000000 as well and still realize that it can safely configure external SDRAM. Attention 1610 Innovator Users/Owners: Please give this patch a try on your boards as well, as it should work exactly the same. Change log snippet: * Patch by Michael Bendzick, 30 Aug 2004: - Improve platform.S code for omap1510inn that detects whether code is running from SDRAM or not. Patch allows SDRAM to be configured if code is running out of SRAM at 0x20000000. -Michael Bendzick Systems and Software Engineering Logic Product Development www.logicpd.com

by Michael Bendzick 11 Oct '04

11 Oct '04

Included is a patch to make the TI OMAP 1510 Innovator board make use of the CFI driver and buffered writes, increasing the write speed by a factor of about 10. Change log snippet: * Patch by Michael Bendzick, 30 Aug 2004: - Configure omap1510inn board to use drivers/cfi_flash.c Wolfgang: Note that this patch entirely removes board/omap1510inn/flash.c. If you would prefer to keep this file around for posterity, I could resubmit the patch. -Michael Bendzick Systems and Software Engineering Logic Product Development www.logicpd.com

[U-Boot-Users] [PATCH] lpd7a40x register defs, include consolidation
by Paul Ruhland 10 Oct '04

10 Oct '04

Wolfgang, I know you dislike large patches with many changes but I am hoping you will accept this. I've changed the register definitions to be in the style preferred by the armlinux folks. Unfortunately, I changed this locally before consolidating the board config includes and improving the SDRAM configuration handling. So I can't really submit the latter changes seperately without many small incremental patches and large headaches on my end. I will do it if you insist since these changes are quite an improvement for these boards...but it may take a while. CHANGELOG * Patch by Paul Ruhland, 29 August 2004 - change register definitions to use the __REG style preferred by the arm linux community - add targets to Makefile for all card engine SDRAM configurations - add support for all SDRAM configurations in board config includes, 'sdram_init', and board config.mk - add CONFIG_LPD7A404 to 'ARM base boards' in toplevel README - add CPLD revision detection to handle hardware variations between card-engine revisions - consolidate existing board config includes into generic 'lpd7a40x-10.h' and 'lpd7a40x.h'... differences between boards are small enough not to warrent seperate files

[U-Boot-Users] Generating b-records for DragonBall i.MX
by Steven Scholz 10 Oct '04

10 Oct '04

Hi there, I just hacked a simple script that converts u-boot.bin into a text file containg processor init code, SynchFlash programming code and U-Boot data in form of so called b-records. This can be used to programm U-Boot into (Synch)Flash using the Bootstrap Mode of the MC9328MX1/L 0AFE1F3410202E2E2E000000002073756363656564/ 0AFE1F44102E0A0000206661696C656420210A0000/ 0AFE100000 ... MX1ADS Sync-flash Programming Utility v0.5 2002/08/21 Source address (stored in 0x0AFE0000): 0x0A000000 Target address (stored in 0x0AFE0004): 0x0C000000 Size (stored in 0x0AFE0008): 0x0001A320 Press any key to start programming ... Erasing ... Blank checking ... Programming ... Verifying flash ... succeed. Programming finished. So no need for a BDI2000 anymore... ;-) This is working on my MX1ADS eval board. Hope this could be useful for someone. (Maybe we even want to include this into the tools directory.) Steven

[U-Boot-Users] [PATCH] Support for new boards MPC8541CDS and MPC8555CDS
by Jon Loeliger 10 Oct '04

10 Oct '04

Wolfgang, This patch adds support for two boards in the new CDS family. These boards already have CPU support in cpu/mpc85xx, so only the board directories are added with this patch. It should apply against current CVS with ``patch -p 2''. Thanks, jdl * Patch by Jon Loeliger, 24-Aug-2004 Add support for the MPC8541 and MPC8555 CDS boards.

[U-Boot-Users] [PATCH] CONFIG_ETHxADDR consolidation
by Jon Loeliger 10 Oct '04

10 Oct '04

Wolfgang, Here is a patch that basically converts a scattering of #if (defined CONFIG_PN62) || (defined CONFIG_PPCHAMELEONEVB) || \ (defined CONFIG_MPC8540ADS) || (defined CONFIG_MPC8560ADS) || \ (defined CONFIG_MPC8555CDS) areas into this: #if defined(CONFIG_ETH1ADDR) This affects the files: common/cmd_bdinfo.c include/asm-ppc/u-boot.h lib_ppc/board.c and the following boards: CFG_GT_6426x CONFIG_PN62 CONFIG_PPCHAMELEONEVB CONFIG_SXNI855T (Dave Ellis OK'ed) CONFIG_SVM_SC8xx CONFIG_MPC8540ADS (me) CONFIG_MPC8555CDS (me) CONFIG_MPC8560ADS (me) CONFIG_440_GX (Travis Sawyer OK'ed) I didn't address the "CONFIG_HAS_ETH1" concept at all here. I don't know the intent of the owner of the PN62, the PPCHAMELEONVB, nor the SC8xx boards, so they may want to either verify these changes or contact me as needed. Note that this patch affects CONFIG_ETH1ADDR, CONFIG_ETH2ADDR, and CONFIG_ETH3ADDR uniformly. Thanks, jdl * Patch by Jon Loeliger, 24-Aug-2004 Made the presence of ethXaddr be dependent on CONFIG_ETHxADDR rather than a collection of board CONFIG_ names. diff -ruN --exclude=CVS u-boot-public-cvs/u-boot-20040823/common/cmd_bdinfo.c internal-development/u-boot-pq3/common/cmd_bdinfo.c --- u-boot-public-cvs/u-boot-20040823/common/cmd_bdinfo.c 2004-06-08 19:34:47.000000000 -0500 +++ internal-development/u-boot-pq3/common/cmd_bdinfo.c 2004-08-19 14:22:18.000000000 -0500 @@ -79,24 +79,33 @@ #endif print_str ("busfreq", strmhz(buf, bd->bi_busfreq)); #endif /* CONFIG_405GP, CONFIG_405CR, CONFIG_405EP, CONFIG_XILINX_ML300 */ + puts ("ethaddr ="); for (i=0; i<6; ++i) { printf ("%c%02X", i ?

Greetings, The attached trivial patch enables ramdisk/initrd tagged param support for OMAP1610 H2. I've also updated CONFIG_BOOTARGS definition to kill off the "mem=32m" substring since that is handled via CONFIG_SETUP_MEMORY_TAGS. -- Regards, George

[U-Boot-Users] [PATCH] Remove static network setup defaults from mx1ads_config
by George G. Davis 10 Oct '04

10 Oct '04

Greetings, I have this pet peeve about including local network setup details in target config files. These details should not be hard coded in target config files. They should either be manually enterred at the u-boot command line prompt or obtained via bootp/dhcp. This patch removes local network settings from the mx1ads config file. Also, N.B., that you need to provide your own target unique MAC address (setenv ethaddr) because the MX1ADS board vendor did not provide one for you (shame on them : ). Again, it's a bad idea to hard code ethaddr in the default board config for many reasons. Meanwhile it's trivial to do `setenv ethaddr` and shoot yourself in the foot but then at least you're pulling the trigger yourself. -- Regards, George

[U-Boot-Users] [PATCH] Use manifest constants from mach-types.h when setting bi_arch_number
by George G. Davis 10 Oct '04

10 Oct '04

Greetings, The attached patches update ARM boards to use manifest constants from mach-types.h when setting bi_arch_number. I've split this change into two patches. The first patch includes the bi_arch_number changes for all ARM boards which either have no disparity between machine numbers/names or I'm otherwise confident that the machine numbers/names are correct. The second patch includes updates for ARM boards which were either never registered or the machine number has changed since the board was first submitted. N.B. Some of the boards in the second patch have "hijacked" the numbers of other ARM machines. Owners of those boards should register their boards and obtain an official machine number here: http://www.arm.linux.org.uk/developer/machines/?action=new -- Regards, George

[U-Boot-Users] Is this a bug? /rtc/date.c
by Robin Getz 10 Oct '04

10 Oct '04

For architectures/boards which use the to_tm function in /rtc/date.c (which is alot) Dates up to 19Jan2038 03:14:08 work fine, but dates after don't: BOOT> date 011903142038 Date: 2038-01-19 (Tuesday) Time: 3:14:01 BOOT> date Date: 2038-01-19 (Tuesday) Time: 3:14:03 BOOT> date Date: 2038-01-19 (Tuesday) Time: 3:14:04 BOOT> date Date: 2038-01-19 (Tuesday) Time: 3:14:06 BOOT> date Date: 1970-01--24854 (Saturday) Time: -3:-14:-7 BOOT> date Date: 1970-01--24854 (Saturday) Time: -3:-14:-3 BOOT> date Date: 1970-01--24854 (Saturday) Time: -3:-13:-59 This is due to the file the function math, or definition, depending what/where you think the bug is. (or if you think it is a bug at all). void to_tm(int tim, struct rtc_time * tm) because tim is a signed int, dates past 19Jan2038 03:14:08 show up as 1970 with negative days/hours. (ie. the date of 01jan2039 shows up as 1970-01--24507 (Wednesday) Time: -5:-27:-15) Potential solutions: 1) fix math, so negative years show up as years : dates can be set from 1902 to 2038 : 102 years ago, to 34 years in the future). OR 2) change function to be defined as: void to_tm(unsigned int tim, struct rtc_time * tm) which allows things to work until 2106, with existing math. OR 3) leave it alone, by 2010 everyone will have moved to 64-bit time_t, and things will be OK. OR 4) error if someone tries to set the date past 19Jan2038 03:14:08 (this is what Suse 9.0 does). I never checked to see what happens if I let Linux roll over - I didn't feel like crashing my workstation for test purposes, however, then you still need to do #1 above. I will check it out on an embedded target tomorrow. Because this affects so many architectures/boards, I thought I would ask: a) Does anyone care? b) What is the preferred method to fix? (I tried option 2, because it is the most trivial, and it seems to work fine for me). Thoughts? Opinions? -Robin

[U-Boot-Users] Simple JTAG programming tools
by Ing.Gianfranco Morandi 10 Oct '04

10 Oct '04

Dear collegues, forgive me if this subject, is not properly addressed into this list, but I think that almost all of us have been working with Flash. I'm currently working on ixp425 and by searching on the net I found a source code named JflashMM. This code seems to work in conjuction with a .dat (or .txt) file which contains the board configuration (only for pxa250). Anybody has already use this program over the ixp425 development platform? If yes, may I have the configuration file which has been used for? Many thanks Gianfranco

[U-Boot-Users] How to disable serial console completely?

Hi, I'd like to mask serial console totally for system deployment. When I set the console output by '#define CONFIG_8xx_CONS_NONE 1' and made a LCD image, I got the following compiling errors. What should I do next to disable serial console completely? Yeah, README mentions it a little but not enough, I am afraid. I think there should be a switch in <board.h> to disable the serial console simply.

[U-Boot-Users] [PATCH] common framebuffer for PXA and MPC8xx
by himba 10 Oct '04

Hi, I reworked my previous proposal for common framebuffer interface on PXA and MPC8xx (other platforms should find it usefull too). There are some differences in contrast to patch I posted on 08.08.2004. They are: o got rid of two extra header files (pxafb.h and mpc823fb.h) introduced earlier o all common stuff is in include/lcd.h and common/lcd.c o CPU dependent stuff remains in cpu/mpc8xx/lcd.c and cpu/pxa/pxafb.c See my previous post for more details. I tested that patch does not break pxa and 8xx boards with ./MAKEALL [pxa|8xx]. CHANGELOG: Patch by Hinko Kocevar, 21 Aug 2004: Group common framebuffer functions in common/lcd.c Group common framebuffer macros and #defines in include/lcd.h Provide calc_fbsize() for video ATAG regards, himba

[U-Boot-Users] Proposed change; What do you think?
by Jon Loeliger 10 Oct '04

10 Oct '04

Guys, I'd like to get your opinion on a proposed change to a few files that handle some aspects of the various enetaddr fields as found in asm-ppc/u-boot.h, common/cmd_bdinfo.c and lib_ppc/board.c. In particular, I'd like to propose a shift from having these fields be present when certain boards are #defined to having these fields be present when CONFIG_ETH1ADDR symbols are defined. So, don't take the following as a literal patch. It is just some cut-n-paste diffs to show what I mean. There are only a few boards for which this might make a difference. I'm the bit swizzler for most of them (MPC85xxXDS), but the others include the PN62, the PPCCHAMEONEVB, the 440GX, the GT_6426x. SXNI855T, SVM_SC8xx and possibly the DB64360, DB64460, CATcenter, and OCOTEA boards. The latter define CONFIG_ETH1ADDR but don't have their cases include in places like the coomon/cmd_bdinfo.c. I think this sorr of change would make the handling of the ETH1ADDR, ETH2ADDR and ETH3ADDR more consistent across any platform that defines these fields. Opinions? If you buy this, I'll submit a proper patch, of course.

[U-Boot-Users] [patch] trivial parameter type fix for NetSetTimeout
by Andreas Engel 09 Oct '04

09 Oct '04

Attached is a trivial patch not worth mentioning in the ChangeLog. As NetSetTimeout just stores the timeout value in an ulong variable, the value itself should be ulong too. Regards, Andreas

The only think I don't see (and have been looking for a standalone app that I am writing, is the difference between load address and entry address. In the hello_world.c application, it's configured to run at address 0x00040004, but the load address is 0x00040000 - why in this case is there a 4 byte difference. => tftp 40000 /tftpboot/hello_world.bin ... => go 40004 This is another test. I assume that this is a toolchain issue, and may be offtopic for this list. A slightly different issue - I know that you can load up an elf image as a standalone app as well, but I don't seem to be able to pass it any command line args. => tftp 1000000 /tftpboot/hello_world => bootelf this is another test fails, becuase U-boot trys to pass "this is another test" to bootelf, and it doesn't like it. -Robin

[U-Boot-Users] problem about pci target mode
by liuyong 09 Oct '04

09 Oct '04

my cpu is 440gx, and my board is like ocotea. the u-boot version is 1.1.1. I want to configure the board works at the target mode. I check the register sdr0_sdstp1 is 0x80010980, so i am sure that PAE and PHCE is disabled, and only PISE is enabled. But the register sdr0_xcr, sdr0_xpllc and sdr0_xplld is 0, which is initialized with sdr0_sdstp1. the host cannot recognsie the board as a PCI device. Maybe i forget to configure some registers, somebody help me. 　　　　　　　　liuyong 　　　　　　　　ly(a)ncic.ac.cn 　　　　　　　　　　2004-10-09

Wolfgang Denk wrote: >How could you fix this? As you suggested - just a simple offset (exactly the same will need to go into the Linux kernel). If the overflow occurs - (if you see a date less then 18Sept1974, assume roll over has occurred, add 4 years, 9 months, and 17 days). This will set things to the same day of the week structure as the roll over date (19Sep2058 is a Thursday, and so is 19Sept1974). This also should handle the leap years calculations properly. After this it is a simple matter of just adding 84 years to the return value or display of the function. >U-Boot will probably not even be running when the rollover happens, so it >has zero chance to notice. U-boot may not have to be alive when rollover occurs to have an issue - for a contrived example that has less chance of actually happening than me willing the lotto, if you set U-Boot up to check a network connection monthly for updates, after 2058 it stops checking, because U-boot believes that Oct2058 never occurs. However, by doing the above, all than happens is delaying things until 2087, and then you run into the same problem. But since I plan on being dead by then, I am OK with that. (I'd like to be around in 50 years, but not 80). -Robin
