[U-Boot-Users] Command line parsing question
by Jeff Angielski 12 Mar '04

12 Mar '04

u-boot-1.0.0/MPC8260 custom board When I type in commands at the command prompt and hit enter, some of the commands are getting run twice. For instance, version gets run twice while an md runs only once. => version version U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) => U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) => md 0x0 1 md 0x0 1 00000000: ff000000 .... => One thing to note about my setup is that I am accessing the serial console using telnet over a remote serial devices server. So the whole telnet end-of-line issue and the processing of CR,LF, and NUL come into play. Snooping the network and watching the character counts on the seriver server's serial port, I can see that each time I hit <Enter> there are two characters going over the serial line (CR-LF or CR-NUL) to the target. My questions are: 1) Has anybody else encountered this problem? I already googled for an answer but came up with nothing. 2) Does anybody have any idea why some commands are working and others are not? I would expect that either all would be repeated or none of them would be repeated. Thanks, Jeff

If you want to use a SRAM based version, you will probably have to modify U-Boot for it (except your board has jumpers to swap SRAM and flash in the memory map).

I just had the same problem today. In our case, turning off CR/LF and only sending ^M helped. As to why only some commands get run twice: The longer commands stops the serial port polling long enough that uboot drops the the LF after getting the CR. The shorter ones finish faster, and the last character gets interpreted as a nev return. > -----Original Message----- > From: u-boot-users-admin(a)lists.sourceforge.net > [mailto:u-boot-users-admin@lists.sourceforge.net] On Behalf > Of Jeff Angielski > Sent: Thursday, March 11, 2004 17:41 > To: u-boot-users > Subject: [U-Boot-Users] Command line parsing question > > > > u-boot-1.0.0/MPC8260 custom board > > When I type in commands at the command prompt and hit enter, > some of the commands are getting run twice. > > For instance, version gets run twice while an md runs only once. > > => version > version > > U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) > => > > U-Boot 1.0.0 (Mar 11 2004 - 12:24:15) > => md 0x0 1 > md 0x0 1 > 00000000: ff000000 .... > => > > One thing to note about my setup is that I am accessing the > serial console using telnet over a remote serial devices > server.

RE: [U-Boot-Users] [PATCH] New ADS GraphicsClient+ board port
by Kerl, John 12 Mar '04

12 Mar '04

Our brand-new board has flash byte-swapped. When we respin (we only made 5 in the first batch) we'll fix it. But for now, it's backward. And it turns out (so far) that there are minimal changes in the CFI code, which could be #ifdef'ed. Actually I'm using a strataflash.c from another board, but I don't think that matters too much -- it's still CFI-driven. -----Original Message----- From: u-boot-users-admin(a)lists.sourceforge.net [mailto:u-boot-users-admin@lists.sourceforge.net] Sent: Thursday, March 11, 2004 5:01 PM To: George G.

I am using the CFI driver on a BE system but I have the LE option defined since my flash is byte swapped. So that works for me, but I have to override the _LITTLE_ENDIAN define in just that file. So I think it should somehow look for a different define to override how it works. IE something like CONFIG_FLASH_CFI_BYTE_SWAP or something. Comments?

George,Wolfgang, Well done. I modified my configuration file to enable CONFIG_CMDLINE_TAG and I can now pass command line arguments to the kernel. Yipee!! I also checked the location of the BOOT_PARAMS phys addr and they were the same at 0x30000100. I've also noticed that the error I was reporting earlier in the week : "Warning: bad configuration page, trying to continue" has DISAPPEARED. All this excitement in one day!! One thing (there's always one more) ... does U-boot support writing to Intel Strata Flash? Thanks again, Dave "George G.

[U-Boot-Users] Newbie needs help with RAMDISK
by Luke Fimmerzane 10 Mar '04

10 Mar '04

Hi, I'm new to u-boot and would like to mount my rootfile system on a RAM disk. Its an arm 9 target. I'm using a book from KARIM YAGHMOUR called Building Embedded Linux systems as a reference guide to help with creating the RAM disk and understand the features of u-boot. (There's a really good section on u-boot in this book). I've managed to create the ramdisk, download it to my target but when I boot I get this message (only relevant sections included): Kernel command line: root=/dev/ram ...... ...... RAMDISK driver initialized: 16 RAM disks of 4096K size 1024 blocksize ...... ..... cramfs: wrong magic FAT: bogus logical sector size 65535 Kernel panic: VFS: Unable to mount root fs on 01:00 AAgh!!! Where could I have gone wrong!! I know this is a voluntary site but if someone could give me some give me a few hints then thanks.

[U-Boot-Users] Memory Caching in Interrupt mode
by Sharad Gupta 10 Mar '04

10 Mar '04

Hi All, I am using UBoot as a firmware and boot loader for a custom development board based on MPC7455. I understand UBoot is not intended for use in interrupt modes, but I thought it does no harm in outputting some text on serial console everytime an interrupt comes in, say a timer interrupt (every 1 sec). I am using BDI2000 to start debugging at 0x900. But my problem is that since address translation is turned off while processing interrupts, I am not able to write to the serial port address since processor caches it and does not really push it out to the serial port. I am using ns16550 driver and the serial port is at 0x60000000. Whats the work around for this problem ? 1. Shall I turn the address translation on, but I am not sure if its safe to do that, and even if I do that where exactly should I do that, in timer_interrupt routine or transfer_to_handler routine ? 2. Or shall i disable the data caches while processing interrupts ? Thanks Sharad.

Could you mask the following code in YOUR_BOARD.h? /* #define CONFIG_CLOCKS_IN_MHZ 1 ** clocks passsed to Linux in MHz */ For 2.4.x kernel,LINUX use Hz as the system frequency unit instead of MHz.

[U-Boot-Users] Problem booting MontaVista 3.0 Linux on IBM 405EP Bubinga board
by Andy Vo 09 Mar '04

09 Mar '04

Hello all, I am using U-boot with Linux version 2.4.18 but booting hung at = "Uncompressing Kernel Image...OK".=20 I modified the bd_info structure in the kernel (file = include/asm-ppc/ppcboot.h) to match the bd_info structure of U-boot = (file include/asm/uboot.h) as suggested in the U-boot manual.

[U-Boot-Users] u-boot on a quad processor board
by Frank 09 Mar '04

09 Mar '04

I have u-boot running concurrently on all 4 processors on our multi-processor board. Anyone interested in this. If so I will clean up my code and submit a patch. Also, my next task is to keep u-boot in flash (with a limited number of commands) if the sdram fails. This is will allow the user to peek and poke from the command line to configure the sdram controller or debug sdram so it (u-boot) can complete the booting process to sdram. This the only short coming I can see that u-boot has.:-) __________________________________ Do you Yahoo!? Yahoo! Search - Find what you�re looking for faster http://search.yahoo.com

[U-Boot-Users] Warning: bad configuration
by asnua＠eircom.net 08 Mar '04

08 Mar '04

Hi, I finally managed to boot my S3c2410 ARM board using u-boot. However, all is not plain sailing. Problem 1: I've noticed that whenever I set up the environment variable 'bootargs' its value is never passed to the kernel. I can now only change the kernel command line by using make menuconfig for the kernel and changing the default command line in the kernel but this means I have to keep re-compiling the kernel if I want to have a different kernel command line! Problem 2: I've also noticed that I get a 'Warning: bad configuration page, trying to continue' message which I've read is to do with the kernel expecting a tagged list of parameters from the bootloader but the bootloader is not setting it up where the kernel expects it. Can someone answer the following: (1) Does u-boot use param_struct or kernel tagged list. Or does it convert the old style param_struct to a tagged list? (2) What can I do to get the kernel to 'see' the 'bootargs' env variable. Many thanks for your help, Dave Attached : o/p from board on boot up SMDK2410 # bootm ## Booting image at 33000000 ...

[U-Boot-Users] IDE and SCSI devices in U-Boot
by sudhakar rajashekhara 08 Mar '04

Hi All, We have ported U-Boot and Linux-2.4.22 onto a custom powerpc board. We have a Serial ATA card (SATA150 Tx2plus) sitting on PCI, which supports 2 devices. A Hard Disk has been connected to one of the port of the Serial ATA card. Linux identifies this Hard Disk as a SCSI device and configures it properly. Now I want to boot Linux from the the Hard Disk using U-boot. Can I configure the Hard Disk as an IDE device from U-boot or do I have to configure it as a SCSI device?

[U-Boot-Users] PPC405GPr reset troubles
by Stephen Williams 07 Mar '04

07 Mar '04

This may be slightly off-topic, but the hardware is as right as I can get it, so I'm looking for some sort of software problem. I am having trouble with the "reset" command, and the /SysReset in particular, in connection with the EBC clock settings. The PSR (Pin Strapping Register) is spontaneously changing values on the /SysReset. In particular, the external bus clock divisor is changing from /4 to /2. I've added a dump of the PSR right where U-Boot prints the CPU speeds, and I get the following: U-Boot 1.0.2 (Mar 5 2004 - 17:03:00) XXXX PSR=0xfdfc0ce0 CPU: IBM PowerPC 405GPr Rev. B at 266.500 MHz (PLB=133, OPB=33, EBC=33 MHz) PCI sync clock at 33 MHz, internal PCI arbiter enabled 16 kB I-Cache 16 kB D-Cache [...etc...] ñ> reset U-Boot 1.0.2 (Mar 5 2004 - 17:03:00) XXXX PSR=0xfdf80ce0 CPU: IBM PowerPC 405GPr Rev.

But the PSR is read-only?

Well gee, it seems like flash_print_info in particular should go into the cmd_flash.c file, *inside* the (CONFIG_COMMANDS & CFG_CMD_FLASH) section. The flinfo command is the only place it is used. There are a few other functions like that, but print_flash_info is the most glaring example. -- Steve Williams "The woods are lovely, dark and deep. steve at XXXXXXXXXX But I have promises to keep, http://www.XXXXXXXXXX and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep."

[U-Boot-Users] Proposal to add "ispeed" (I2C speed) command
by listmember＠orkun.us 04 Mar '04

04 Mar '04

We have some instrumentation hanging on I2C bus. I would like to introduce a new u-boot command ispeed to set the i2c speed so fast devices would not be constrained to the lowest denominator speed. If desired we can make be conditionally included if CONFIG_CMD_ISPEED (suggestions?) so it would not take space when it is not needed (or desired) on a particular board. The proposed syntax would be. ispeed {i2c bus speed} Since u-boot uses hex: 100kHz => 186A0, 400kHz => 61A80 I would also set an environment variable in ispeed command indicating current i2c speed ("i2cspeed") so it could be used in scripts. Looking for your comments? Best regards, Tolunay

[U-Boot-Users] Serial ATA driver problem
by sudhakar rajashekhara 04 Mar '04

04 Mar '04

Hi All, We have ported u-boot and linux-2.4.22 on to a custom POwerPC MPC8280 board. Everything is working fine except the Serial ATA driver. We are using SATA150 Tx2plus serial ata card which sits on PCI. We got the driver source code from the public domain. We have integrated the driver source code to the kernel and driver module loads itself when linux kernel is coming up. As soon the module is loaded we get a device information string as "aMtxro6 0Y080M". (We have tested the same driver on a x86 machine and there the driver works perfectly and the device identification string got there is "Maxtor 6Y080M0".) After this the board comes up correctly. When we try to partition the device using the fdisk command (fdisk /dev/sda), we get the following errors: ======================================================= # fdisk /dev/sda pdc-ultra:[warning] disk1 ATA timeoutat LBA 0x0 pdc-ultra:[warning] submit cam busy scsi : aborting command due to timeout : pid 10, scsi0, channel 0, id 0, lun 0 0x28 00 00 00 00 00 00 00 08 00 pdc-ultra:[info] scsi abort success pdc-ultra:[warning] disk1 ATA timeoutat LBA 0x0 pdc-ultra:[warning] submit cam busy scsi : aborting command due to timeout : pid 11, scsi0, channel 0, id 0, lun 0 0x28 00 00 00 00 00 00 00 08 00 pdc-ultra:[info] scsi abort success pdc-ultra:[warning] disk1 ATA timeoutat LBA 0x0 pdc-ultra:[warning] submit cam busy scsi : aborting command due to timeout : pid 12, scsi0, channel 0, id 0, lun 0 0x28 00 00 00 00 00 00 00 08 00 pdc-ultra:[info] scsi abort success scsi0 channel 0 : resetting for second half of retries.

[U-Boot-Users] Booting Linux stops at Starting Kernel, perhaps an endian problem
by Sonia Martinez 04 Mar '04

04 Mar '04

Hi all, We're trying to make Linux run on our DBPXA based platform. U-boot works fine, we can communicate through serial line with it, using Minicom or HyperTerminal. The kernel and file system image (u-boot multi image) is loaded into RAM with kermit at 0xa3100000. But, when we try to boot linux with the bootm command, it stops at "Starting Kernel" (We're working with Linux kernel 2.4.19 patched with -rmk7-pxa1 in eLinOS distribution). In order to see if something went wrong, we've compared vmlinux.bin before compression and the kernel decompressed in RAM, in position Load_address. We've found that the information is the same but one is in big endian (in RAM) and the other one in little endian (vmlinux.bin). The platform works in little endian, so this is probably the problem. How can we solve it?? Is it a gunzip problem?? Thanks in advance Best regards, Sonia

Re: [U-Boot-Users] Enabling watchdog for MPC850
by Shlomo_Kut＠mksinst.com 04 Mar '04

Hi, I enabled the watchdog both in u-boot and in Linux and it worked fine. Linux rebooted itself after printing a warning message on the console. Thanks. One thing I don't understand form the watchdog driver documentation. >In open-only mode, the watchdog will not expire if the device file is not opened by any process, while in >always mode the behavior is independent of the device file being opened. How can you set open only mode without opening /dev/watchdog? Could anybody direct me to an example of a simple watchdog application using the regular API? regards Shlomo Kut Software Engineer MKS Instruments Tenta Products Tel: 972-8-9181015 Fax: 972-8-9181020 www.mksinst.com Wolfgang Denk <wd(a)denx.de> Sent by: wd(a)denx.de 03/03/2004 01:54 AM To: Shlomo_Kut(a)mksinst.com cc: u-boot-users(a)lists.sourceforge.net Subject: Re: [U-Boot-Users] Enabling watchdog for MPC850 Hello, in message <OF711943DA.EE1C86A3-ON42256E4C.0033BE6B-08256E4C.0033E9D8(a)mksinternal.com> you wrote: > > >Please define "crash".

[U-Boot-Users] Compile error: # error The DS1307 is specified only up to 100kHz!
by listmember＠orkun.us 03 Mar '04

03 Mar '04

rtc/ds1307.c thas the following code fragment. #if CFG_I2C_SPEED > 100000 # error The DS1307 is specified only up to 100kHz! #endif Although, the datasheet says the part is 100kHz only, newer parts operates at 400kHz as well. I would like to eliminate this section of code (or at least change the #error to #warning). Leave the decision to use this part above 100kHz (and pros and cons) to the board designer! I will send a patch for this... Any comments? Best regards, Tolunay

[U-Boot-Users] bd->bi_opbfreq initialization lib_ppc/board.c
by listmember＠orkun.us 03 Mar '04

03 Mar '04

The following is the code fragment from lib_ppc/board.c. %%% begin fragment %%% #if defined(CONFIG_405GP) || defined(CONFIG_405EP) bd->bi_pci_busfreq = get_PCI_freq (); #ifdef CFG_OPB_FREQ bd->bi_opbfreq = CFG_OPB_FREQ; #else bd->bi_opbfreq = 50000000; #endif bd->bi_iic_fast[0] = 0; bd->bi_iic_fast[1] = 0; #endif #endif %%% end fragment %%% Why is bi_opbfreq not initialized as: bd->bi_opbfreq = get_OPB_freq(); get_OPB_freq() returns the actual OPB frequency based on PLB freq and PLB:OPB divisor (based on pllmr & strap read only registers in PPC405). This value is not used by u-boot but Linux uses it in I2C divisor initialization (linux/drivers/i2c/i2c-ibm_iic.c). On Cogent CSB272 board the OPB freq is set to 16.67Mhz so the effective I2C clock was much lower because wrong value was communicated to Linux. I patched my version of board.c to use get_OPB_freq() in the else case (replaced constant 50000000 with get_OPB_freq() call) and it worked well. I personally do not see why CFG_OPB_FREQ is needed at all (only one board is using it and set to 50Mhz). If nobody objects, I would like to send a patch for it. 2 choice for the patch: 1) I can send a patch so CFG_OPB_FREQ is removed and bi_opbfreq is always initialied to correct value via get_OPB_freq(). 2) I can keep CFG_OPB_FREQ override (for that one board) and change the default in else case to get_OPB_freq(). Which one would you favor? Regards, Tolunay

[U-Boot-Users] bd->bi_iic_fast initialization in lib_ppc/board.c
by listmember＠orkun.us 03 Mar '04

03 Mar '04

Speaking of the code fragment below (from lib_ppc/board.c), I would like to send a patch so that bi_iic_fast is initialized from "i2cfast" environment variable (if defined). This parameter is passed to Linux to set the i2c driver mode. Of course, this variable should be in the environment when system is booting and any change should be saved to environment first and board should be reset to take effect. There are other environment variables in the same file that behave this way. This is only going to be used when CONFIG_405GP and CONFIG_405EP is defined. What do you think? %%% begin fragment %%% #if defined(CONFIG_405GP) || defined(CONFIG_405EP) bd->bi_pci_busfreq = get_PCI_freq (); #ifdef CFG_OPB_FREQ bd->bi_opbfreq = CFG_OPB_FREQ; #else bd->bi_opbfreq = 50000000; #endif bd->bi_iic_fast[0] = 0; bd->bi_iic_fast[1] = 0; #endif #endif %%% end fragment %%% Regards, Tolunay

Hi, I am having a problem enabling the watchdog in u-boot. It causing the Linux load to crash. Do I have to enable watchdog support in u-boot for the mpc_8xx driver to run?

[U-Boot-Users] about AdderII(MPC852T) board
by John Zhou 03 Mar '04

03 Mar '04

Hi, I want to design a board based on MPC852T like AdderII used in u-boot. For speeding our product time to market, I hope to have same hardware configuration as AdderII board as possible as we can. (1) Does anybody know which GPL configration for SDRAM? I mean which GPLx line are used for CAS or RAS or WE? (2) which two port pins are used for controlling MII? Thanks in advance! John

[U-Boot-Users] param_struct vs tagged list
by asnua＠eircom.net 02 Mar '04

02 Mar '04

Hi again, I took a break from trying to get u-boot up and running on my S3c24210 based board. I went back and looked at how the VIVI bootloader which comes with the board works. I should add that when I use VIVI I can boot the exact same kernel without any problems! The board is actually built by Meritech. Its called a S3C2410 Tk (training kit). I'm getting it to the point with u-boot that its uncompressing the Linux kernel and then dies. The actual message is : Uncompressing Linux................................................ done, booting the kernel. (1) Has anybody managed to get u-boot running on this particular board? (2) Looking at the VIVI bootloader it looks as if it uses 'param_struct' to pass parameters to the kernel. I think that u-boot uses a tagged list. Could this be the problem or can a kernel accept both types? (3) I've checked that BOOT_PARAMS(0x30000100) is the same as gd->bd->bi_boot_params = 0x30000100; (4) The param_struct in VIVI has the following 3 items set up: page_size = 0x1000; nr_pages=0x4000000>>12 commandline. Can't see corresponding U-boot versions? (5) Any other ideas? Thanks again, Dave

[U-Boot-Users] [PATCH] PCMCIA card support for PXA/WEPEP250
by Leon KUKOVEC 02 Mar '04

02 Mar '04

Hi everybody, New Feature: * support for PCMCIA card on WEPEP250 board. Notice: The default configuration of WEPEP250 board does not include PCMCIA support. To include PCMCIA and IDE support the WEPEP250 configuration has to be adjusted. Note that I have changed TEXT_ADDRESS for WEPEP250 board to start at 0xA1000000. If my understanding is correct, Linux kernel will use the memory that was occupied by U-Boot code while running in RAM. Tweaking can be done later. In case of any issues, let me know. -- Best Regards, Leon.

[U-Boot-Users] [PATCH] lba48 support & 64bit vsprintf
by Rune Torgersen 01 Mar '04

01 Mar '04

I tried to send this to the list Friday, but it apparently got lost on the way... In any case.. This adds some ifdefs around the code so it should not increase the memory footprint on any system not needing LBA48 support. LBA and vsprintf are completely separated into the two patches, and they should not be dependent on eachother. (eccept if some of the CFG_ variables are set -----Original Message----- From: Rune Torgersen Sent: Friday, February 27, 2004 13:56 To: u-boot-users(a)lists.sourceforge.net Subject: [PATCH] lba48 support & 64bit vsprintf Added some CONFIG and CFG variables to for LBA48 support and for 64bit printing. Now you can use LBA48 and not use 64bit in vsprintf. LBA48 now works without 64bit. Changelog Rune Torgersen - Added LBA48 support (CONFIG_LBA48 & CFG_64BIT_LBA) - Added support for 64bit printing in vsprintf (CFG_64BIT_VSPRINTF) - Added support for 64bit strtoul (CFG_64BIT_STRTOUL) README is also updated for these variables Remove the two last CHANGELOG lines if you do not want to mess with vsprintf Rune Torgersen System Developer Innovative Systems LLC 1000 Innovative Drive Mitchell, SD 57301 Ph: 605-995-6120 www.innovsys.com

RE: [U-Boot-Users] IDE LBA48 support and vsprintf 64bit support

> What do you think your "fix" to vsprintf will do? Enable me to print numbers in decimal that are longer than 32 bit. > Forget it. I will not add "long long" support to printf > without a really good reason. That's ok. That is the reason I split the patch into two parts. The IDE patch works without it, but will not be able to print sectors over 32bit. (That is a 2.1TB disk, so it wont be a problem for a few years :)
