[U-Boot-Users] uImage wrapper removal?
by Tom Guilliams 15 Aug '03

15 Aug '03

Does anyone know if there's a utility to remove the U-Boot wrapper from a uImage (gzipped kernel, etc)? I'm creating a single uImage with kernel and ramdisk and I need to extract the kernel, replace the ramdisk and put it all back together after my Linux kernel has booted. I believe objcopy will allow me to extract the kernel from kernel/ramdisk ELF image but that's off-topic. Just checking to see if there's something already out there of if this has been discussed before. Thanks, Tom

[U-Boot-Users] Hardhat Linux over-riding u-boot IRQ/ PCI configuration mappings
by C Doyle 15 Aug '03

15 Aug '03

Hello all, I'm using u-boot4 to boot an MPC8266ADS-PCI board, which does so successfully. I have a 4-port USB2.0 hub in one of the pci slots. The problem is twofold. 1. When I download hardhat linux to the board using NFS it seems to override u-boots PCI memory map, and 2. doesn't seem to pick up the Interrupt controller properly as it cannot assign an IRQ to the devices (or I am not assigning the IRQ properly). Does anyone know what I have to do to change the hardhat settings to either - correctly mirror what has been setup in u-boot, or ignore its own settings and simpliy use the existing bootloader configuration. Thanks in advance for any correspondence.

[U-Boot-Users] [PATCH] changes to IDE driver for LSB machines
by Marc Singer 14 Aug '03

14 Aug '03

Aside from the ARM additions, there are changes to allow the IDE code to run on other little endian machines IA32, mips. BTW, the macro names, WORDS_BIGENDIAN and BYTES_BIGENDIAN come from autoconf. Also, the endianness of mips isn't clear. Like PPC, it can do either and as far as I can tell both are supported by Debian. Cheers.

[U-Boot-Users] standalone code
by Philippe Simal 14 Aug '03

14 Aug '03

Hello, I'm running u-boot-0.3.0 on an IBM PPC440GP EBONY board . The next stage is to port u-boot to our custom designed board. In the meanwhile I'm writing some hardware debug code that does not use any kernel. (1)First I tried to run it as a standalone program just like the 'hello world' example. The problem is that I do not have access to the drivers used by u-boot. I only can use some system calls like mon_printf()... So I tried to link my debug code directly to the u-boot code with an entry point just before the call main_loop() in board.c. This works fine except that I cannot use function pointers used in my debug menu . (2)I know this has something to do with the code relocation from flash to sdram so I tried to relocate all my pointers. Ok that didn't work. So my questions are, (1) is it possible to make a standalone pease of software that runs in sdram with the full use of the u-boot drivers? (2) What must I do to use my pointers whitout crashing the ppc. Best regards, Philippe Simal

[U-Boot-Users] IDE and x86 port
by Juergen Beisert 14 Aug '03

14 Aug '03

Hello all, is anybody out there who has a working IDE device on x86 port and u-boot? My u-boot prints: << Model: uSDnsi kDSFC-B 4 Firm: eR v.3010 Ser#: M 3T00580313 Type: Removable Hard Disk Capacitiy: 42188.8 MB = 41.2 GB (515899392 x 512) >> But the device is a "SunDisk SDCFB-4" and has a capacity of only 7872 sectors. 7872 = 0x0000'1EC0 -> 515899392 = 0x1EC0'0000 See: SunDisk SDCFB-4 uSDnsi kDSFC-B 4 It's confusing me, because long time ago I have written a small routine to read the hard disk device information. I read 256 words into a buffer, too. To get the right capacity value I have to swap the upper and lower word of the capacity long word. u-boot does the same, but after the swap capcity has the wrong value. I have compiled the cmd_ide.c with "gcc -E" to see, to what the macros get expanded and it seems ok. The swap seems the right way, but results into a wrong value (perhaps only on my port).

[U-Boot-Users] Serial console for Linux at SCC1?
by Steven Scholz 13 Aug '03

13 Aug '03

Hi there, on my MPC8xx board I use SMC1 as serial console for U-Boot and Linux. I start linux using these bootargs setenv bootargs root=/dev/mtdblock0 rw console=ttyS0 Linux tells me ... CPM UART driver version 0.04 ttyS0 on SMC1 at 0x0280, BRG1 ttyS1 on SMC2 at 0x0380, BRG2 ttyS2 on SCC1 at 0x0000, BRG3 ... Everything is fine. BUT: Now I just wanted to set bootargs to "root=/dev/mtdblock0 rw console=ttyS2" in order to get a Linux console at a different Port. But it's not working, i.e. I can't see any messages at ttyS2. Could it be that since I configured U-Boot to use SMC for console, it's not going work with SCC anyway? Thanks, Steven

[U-Boot-Users] FEC problems on mpc852
by Chris Simmonds 12 Aug '03

12 Aug '03

Hi, I am having some problems getting the FEC to work, perhaps someone on the list has seen something like it and can help me out? The problem occurs in fec_send (in cpu/mpc8xx/fec.c): the BD_ENET_TX_READY bit is set but never cleared, indicating that the packet is ready to send but the hardware is not processing it. The receive side works fine: packets are received and processed as expected. So, I do not suspect the physical path to the outside world. Anybody any ideas what could cause this sort of behaviour? Any known problems with the 852T? What can I look at to find out what is going on? By the way, this is on u-boot 0.4.4. Best regards, Chris Simmonds

[U-Boot-Users] u-boot in debug mode
by Eli Brin 12 Aug '03

12 Aug '03

Hello, I would like to debug u-boot (0.4.2), on TQM860L, with the BDI2000. Reading the DULG 12.1.2: For parts of U-Boot that run from RAM, i. e. after relocation, use "powerpc-linux-gdb" without arguments, and use the add-symbol-file command in GDB to load the symbol table at the relocation address in RAM. The only problem is that you need to know that address, which depends on RAM size, length reserved for U-Boot, size of "protected RAM" area, etc. If in doubt, enable DEBUG mode when building U-Boot so it prints the address to the console. Hint: I use definitions like these in my .gdbinit file: define rom symbol-file file u-boot end define ram symbol-file add-symbol-file u-boot 0x01fe0000 end My problem is that the system doesn't stop at breakpoints. For example: I have put a breakpoint on do_run and do_printenv functions, but the ppc_8xx-gdb won't stop when I execute the commands on the target. I suspect that the 0x1fe0000 is wrong for me. If I break the program with ctrl^C, and add a breakpoint at the current position (Breakpoint 3 at 0xfdf3f8), then is stops each time I do continue. Adding - #define DEBUG to TQM860L.h, gives me errors on flash.c 1. So, how can I get the correct relocation address? 2. Trying to stop at _start (in start.S) before relocation, also doest not work. The BDI2000 config file is taken from Denx web site. Thank you, Eli Brin

[U-Boot-Users] Port for EP860 board
by chris＠nanometrics.ca 11 Aug '03

11 Aug '03

Hello, I'm new to U-Boot, but have been monitoring this list for a while in anticipation that I'll be using it. I've seen several questions about the EP860 board but it has not yet been added to the valid board types. I'd rather use a working port to the EP860 than redo it myself. I've seen comments that U-Boot expects and requires a "virgin" CPU, fresh out of reset. But until I get a BDI emulator, I don't want to overwrite the original PlanetCore bootloader installed on the board. However it has a RestoreCE configuration parameter which seems to simulate a "virgin" CPU. If I jump to U-Boot in Flash using this option will it work? RestoreCE description from the PlanetCore Bootloader manual: When transferring control to the application, first change the chip enables to map all of memory (other than the internal memory) to the FLASH. The IMMR register is reset to the initial value. The processor looks like it was just reset (more or less). However, chip enables for the rest of memory are left as mapped by the boot loader. An application can examine these chip enables and determine which memory exists and where. The UPM is still programmed for RAM. Control can only jump to FLASH when this option is used. Finally is anyone else using Windows for their development PC? I had a few problems with the CYGWIN defines when I tried building RPXClassic board which is the obsolete version of the EP860. Chris

[U-Boot-Users] Problems with serial output on custom MPC8280 board
by Georg Klug 09 Aug '03

09 Aug '03

Hi all, we developed a custom board with a MPC8280 PowerQuiccII. It has the serial console on SCC3. We already ported the U-boot 0.4.5 (based on the MPC8266 board) to it and it works fine after a Power-on-Reset. The trouble begins when we issue a HRESET. (We usually do this with the BDI2000 box). After this HRESET the serial console occurs to hang randomly. This mean that the U-Boot code hangs in the while loop of serial_putc() function where it waits for the first character to be sent to the console. But unfortunately the BD_SC_READY gets never deasserted. In this situation we tried to reset the CPM manually (with BDI box) once again with the following sequence: - Issue the RESET Command to the CPM - Set register sccm, scce, gsmrh, gsmrl, and psmr for SCC3 according to the settings in serial_init. - Issue the TRX_INIT command to the SCC3. The command was accepted by the CPM (The CPM_CR_FLAG was reset when we re-read the cpcr) We also verified the the dpram parameter portion had the same contents as in the "good working case". - Enable the transmitter and receiver via gsmrl register. But the serial console did not react and the BD_SC_READY was not cleared. No further HRESET could then solve the problem. Only after POR the console showed some output again. This leads us to the impression that somehow the CPM/SCC3 could not properly communicate with the CoreCPU. Does anybody experienced a similar problem? Any hints would be very much appreciated. Kind regards, Georg

[U-Boot-Users] Preparing a KEV7a400 patch
by Marc Singer 07 Aug '03

07 Aug '03

I've successfully ported u-boot to the Sharp KEV7A400 board. It can program flash, boot from the network, and it runs from flash. Before I submit a patch, I believe there are a couple of outstanding issues that you, Wolfgang, want resolved. 1) Dependency on Perl Are you OK with an initial patch that checks for the presence of a Perl interpreter? Since this is the only board using the mkocnfigx script, such a method will be backward compatible. I agree that a shell script of the Perl script must be written. 2) #undef arm It looks like the arm macro may be defined by the compiler. The GCC info pages suggest that this macro may be defined unless -ansi is passed to the compiler. There are a few of ways to resolve this problem. I could change the structure that is broken by the #define. I could leave the #undef intact. I could find a way to remove the #define by passing an switch to the compiler. My preference, of course, is to leave the #undef intact. 3) Trailing whitespace You found some lines in a previous patch to have trailing whitespace. What do you use to detect this?

[U-Boot-Users] 857T scc init
by Brian Rasmussen 07 Aug '03

07 Aug '03

Hi, I�m almost done porting U-boot to a custom HW platform but I have a problem getting the Ethernet port to work correctly. I�m using a 857T with a Realtek 8201BL transceiver. If I run U-boot and press a key so I get to the prompt and then type tftp I see the following behavior. 5 ARP requests are sent but no response is received and it times out and tries again. An ARP response is never received. If I stop U-boot with the BDM and changes RINV in GSMR_L and start again I receive an ARP request and tftp gets called but the transfer stops. To get the tftp transfer to continue I need to change RINV back to normal and run again. The tftp transfer then completes. I can now issue a tftp transfer over and over without making any changes through the BDM. Even the ARP request works every time. This behavior is consistent every time I reboot the system. The only modifications made to the code are the pin-configurations. Has anybody seen this behavior before or have any ideas. Thanks, Brian Rasmussen

If I run U-boot and press a key so I get to the prompt and then type tftp I see the following behavior. 5 ARP requests are sent but no response is received and it times out and tries again. An ARP response is never received. If I stop U-boot with the BDM and changes RINV in GSMR_L and start again I receive an ARP request and tftp gets called but the transfer stops. To get the tftp transfer to continue I need to change RINV back to normal and run again. The tftp transfer then completes. I can now issue a tftp transfer over and over without making any changes through the BDM. Even the ARP request works every time. This behavior is consistent every time I reboot the system. The only modifications made to the code are the pin-configurations. Has anybody seen this behavior before or have any ideas. Thanks, Brian Rasmussen

[U-Boot-Users] Announcement of new DENX U-Boot and Linux Guide
by Detlev Zundel 07 Aug '03

07 Aug '03

Hi, as the URL has leaked onto this list by now anyway, I am somewhat late to officially announce the all-new, ultra-shiny and wonderfully interactive "DENX U-Boot and Linux Guide"[1] (DULG for short). The DULG is the successor of the DPLG previously available in different formats and specialized for different boards from the DENX website[2]. The new DULG in contrast is a Wiki collaboration area (TWiki to be precise) allowing direct editing of its contents. If you never heard of "Wikis" before, [3] should be a good starting point for finding out. In addition to the advantages inherent in a Wiki based site, the DULG web is designed to provide board-specific documentation through the ease of a webform for choosing the target board[4]. Right now there are only two boards to choose from, _but_ one is PowerPC based (TQM8xxL), while the other is MIPS based (INCA-IP). The ELDK[5] sections will of course show the correct information for the selected platform... Disclaimer: If things don't work as you expect them to, remember that this baby is _very_ young, but don't hesitate to ask. There's even a place in the Wiki itself for discussing it[6]. Ok, now its official, so all thats left for me to say is: Browse, enjoy and last but not least _improve_ it by contributing! Cheers Detlev PS: Before making major changes, it is a good idea to get familiar with the peculiarities of the DULG web explained in links from the main web[1]. [1] http://www.denx.de/twiki/bin/view/DULG [2] http://www.denx.de/ [3] http://www.denx.de/twiki/bin/view/TWiki/TWikiSite [4] http://www.denx.de/twiki/bin/view/DULG/BoardSelect [5] http://www.denx.de/twiki/bin/view/DULG/ELDK [6] http://www.denx.de/twiki/bin/view/DULG/DULGFaq -- 14474011154664524427946373126085988481573677491474835889066354349131199152128 If you know why this number is perfect - you're probably a mathematician...

Hello Detlev, Wolfgang, Thanks for your replies, you are completely correct, I should have realised! I had some problems compiling with -O0, however building with -O1 was just as good. Now I have another problem, one which I hope you may have come across before, my debugger is failing to keep track of the updated addresses of static variables after relocation, which makes displaying variables kinda hard :) Any ideas? Mark.

I was responsible for the gdb directory being there - long time ago early in the ppcboot days - when the board I was using had no ethernet and no flash (really!). I would burn ppcboot into an EPROM, then use gdb to download a linux kernel over the serial line and debug it the same way if it crashed (with kgdb). Wasn't too bad at 230400 baud.

[U-Boot-Users] Using the abatron to debug an image in flash
by Mark Doherty 07 Aug '03

07 Aug '03

Hi, Apologies for asking what I suspect is a very simple problem, I am attempting to debug u-boot after relocation and have followed the simple instructions previously posted on this mailing-list, however I am having difficulty in getting the abatron to do as it is told! First up is the target section of the bdi2000 config file : [TARGET] CPUTYPE 8260 BDIMODE AGENT STARTUP RESET JTAGCLOCK 0 BOOTADDR 0x00000100 ;WORKSPACE 0x00000000 BREAKMODE HARD STEPMODE HWBP ;VECTOR CATCH ;DCACHE NOFLUSH ;MMU XLAT 0xC0000000 ;PTBASE 0x000000F0 I'd like to be able to step through the eth_init routine and I am invoking it through a tftpboot command on the console. A trace from gdb illustrates my problem, (note that I have some shortcuts programmed into my .gdbinit routine to set the $pc and to load the symbol file). When the program has loaded into RAM I stop the debugger (hence the SIGSTOP) to insert my breakpoint, for some reason I have problems if I attempt to insert the breakpoint before the code is in RAM (?). $ ppc-linux-gdb GNU gdb 5.1.1 Copyright 2002 Free Software Foundation, Inc.

Just to finish off I am able to configure the ram such that I can debug the application in ram up to the point where relocation occurs so I am fairly confident in my SDRAM setup. Any thoughts or comments welcome, thanks Mark.

[U-Boot-Users] SED13806 and MPC866
by Marco Schramel 06 Aug '03

06 Aug '03

Hi, First i have to say "i am new in embedded Linux". I am very interested in the new 866 of Motorola. For a graphical output the EPSON SED13806 is planned. I've found in the archive that this chip is supported from U-Boot ;-) !! My question is, how to setup and to tell the kernel that the EPSON is its graphical output. The start address in SED13806 is defined by my board with its CSx base address, i think. Is there more to tell as its start address ? How i setup my kernel that a SED13806 exists or has my device driver to do this ?? If you know more useful things about the SED-chip, please let me know.

The boot flash on the KEV7A400 has two sizes of blocks. The first 64KiB is in 8KiB blocks. The rest (63 blocks) are each 64KiB. Will u-boot write memory correctly if I put these blocks into two banks?

Hi, I am new to Linux and U-Boot. I am using the MPC8266 BSP for MPC8266ADS reference board from Metrowerks as my base point to start my project specific board BSP. I am wondering if someone can help with telling me what sets of files I would have to modify in U-Boot to input my board specific details so that the U-Boot will work on my board. Also any other pointers would be really appcreciated. Regards, Divyesh Patel

> needed fixed for the PCI features of the 8266. I have tried > 0.3 and 0.4 but > cannot get it to work. I have u-boot 0.3.0 working with full PCI support, (have not gotten around to try 0.4.x yet) BTW.... Just figured out why it hangs right at FLASH:.... This is when it moves u-boot to SDRAM... If you use the standard 16-MB SDRAM stick that comes with the ADS board, it WILL NOT work with Page Based ingerleave mode. I have only gotten that to work with 64MB and bigger SDRAMs Change CONFIG_PBI in board/mpc8266ads/mpc826ads.c to 0 to use Bank Based Interleave. > First of all I am using ELDK to cross compile the > u-boot source > which seems to work fine.

Both work great. The one for starting at 0xFE000000 gives you the most amount of continous free FLASH, as it puts the boot image at the beginning of the FLASH. The one that starts at 0xFFF00000 puts the mage in the last megabyte of the flash. Flash starts at 0xFF800000. > 2.) Also the settings for the CFG_FLASH_BASE default to > 0xFE000000.

No. For the HRCW setting that the U-Boot 0.3.0 version for the 8266 defaults to, it has to be at 0xFE000000. The flash WILL start here. (and continue 8MB from there). > If someone out there has managed to get this working it would > be great if > you could either explain everything I need to do to get it > blown to the > flash on this type of board.

Try the following: (I don't know if this will work with 0.4.x, it will work with 0.3.0) 1) Leave the jumper (JP3) in position 2-3. 2) use default setting for the MPC8266ADS_config. 3) compile 4) make an image that whatever JTAG/COP thing you use can write to flash. 5) write image to address 0xff800000 (which becomes 0xfe000000 when the jumper is changed) 6) place jumper in position 1-2 (HRCW in FLASH). 7) Reset board. This should work. (console on RS232-1 (top port) at 115200-8n1) The other option is (if you would like the flash at the default place) 1) Leave the jumper (JP3) in position 2-3. 2) Change CFG_HRCW_MASTER in include/configs/MPC8266ADS.h to #define CFG_HRCW_MASTER 0x0cb23645 3) Change TEXT_BASE in board/mpc8266ads/config.mk to 0xfff00000 4) compile 5) write to flash at position 0xfff00000 (start of flash is at 0xff800000) 6) reset.

Ciaran, The stock u-boot-0.4.0 release tarball works just fine for me with the following changes. Mileage may vary based on your configuration ... but here's the only changes I made for mine: In include/configs/MPC8266ADS.h: Change CFG_FLASH_BASE to 0xFF800000 Change FLASH_BASE to 0xFF800000 In board/mpc8266ads/config.mk: Change TEXT_BASE to 0xFFF00000 If SDRAM initialization gives you trouble ... In board/mpc8266ads/mpc8266ads.c: Change CONFIG_PBI to 0 Set your switches to: SW1: All on SW2: All on SW3: 1-on 2-on 3-off 4-off SW4: 1-on 2-off 3-on 4-off 5-on 6-on 7-on 8-off You'll have to rtfm if you don't want to use the BCSR as the HRCW source or if you want to monkey with the PCI clocking options ;-) BTW: PCI worked just fine with several different NICs.

by C Doyle 05 Aug '03

05 Aug '03

Hello all, I am a newbie to u-boot and I am trying to get u-boot0.4.0 to download to the flash on an MPC8266ADS-PCI development board. I managed to get u-boot0.2 on the flash and working as it should but unfortunately it needed fixed for the PCI features of the 8266. I have tried 0.3 and 0.4 but cannot get it to work. Both myself and some guys at Motorola have been trying for 4-6 weeks now to get u-boot & PCI up and running. Has anyone managed to get u-boot to work on this platform with PCI support enabled? If so, I would be greatful if could you mail the .srec to cd7(a)hw.ac.uk First of all I am using ELDK to cross compile the u-boot source which seems to work fine. The problem is that it doesn't seem to like the Flash very much. I am using the Sharp type flash. I have tried the both the default configurations, with no success and also modified the following settings, also without much success. 1.) Within {u-boot}/include/configs/MPC8266ADS.h there are two choices for CFG_HRCW_MASTER depending on which JP setting you want to use - does anyone know which one is best to choose here? 2.) Also the settings for the CFG_FLASH_BASE default to 0xFE000000. From the MPC8266 user manual I noticed that the memory location this relates to is for a 32M SIMM whereas I have 8M which starts at FF800000. I changed this to mirror the user manual and update also the CFG_BR0_PRELIM accordingly (0xFF801801). 3.) I have also played around with the {u-boot_dir}/board/mpc8266ads/config.mk file to no avail. If someone out there has managed to get this working it would be great if you could either explain everything I need to do to get it blown to the flash on this type of board. Like I say I am a newbie to this and probably need to plead ignorance, or b) have a working copy for an MPC8266ADS-PCI that you could send to me as I can't proceed past this point. Any help is very much appreciated. Thanks Ciaran Doyle _________________________________________________________________ Tired of spam?

[U-Boot-Users] Using tools/mkimage
by Marc Singer 05 Aug '03

05 Aug '03

I'm having trouble understanding how an image should be created. It was my intention to use the zImage file already compressed with a loader. RAM starts at 0xc0000000, the kernel wants to load, after decompression, to 0xc00c8000. Normally, compressed kernel images are loaded at 0xc0008000. tools/mkimage -A arm -C none -a 0xc0008000 -d zImage image >From the boot loader, rarp 0xc0008000 bootm The trouble is that it starts executing at 0xc0008000 which is the image header. Based on reading the README, I'm suspicious that I've misconstrued the load addresses and that the loader doesn't support uncompressed images. Any tips?

[U-Boot-Users] Are there any users of tools/gdb/astest.c?
by Detlev Zundel 05 Aug '03

05 Aug '03

Hi, looking through the mailing list archive, it becomes clear that the mentioned "tools/gdb/astest.c" posed (in my view unnecessary) problems for some U-Boot newcomers that stopped them from compiling the main U-Boot code. My question therefore is, does anyone still use this code or has it been obsoleted by binutils? Looking through the code it seems like it dumps ELF file infos for the hard-coded "elf32-powerpc" BFD target so it is of limited use only to the newly supported architectures anyway. If anyone wants to keep the file then please speak up, otherwise I'd like to ask Wolfgang to remove it so there is one less obstacle for new users of U-Boot. Thanks Detlev -- You get 3 opportunities to advertise your Rock band, no more. -- Proposed Symbolics guidelines for mail messages (1984)
