[U-Boot-Users] Don't understand the U-boot debug info

hi, all, I met some problem when I tried to boot my kernel via U-boot. I know something wrong with my kernel. But I don't understand what is the problem. I am using IXP425 processor. The following is printed by U-boot. Can anybody help me to check that?

[U-Boot-Users] Enabling watchdog for MPC850
by Shlomo_Kut＠mksinst.com 03 Mar '04

03 Mar '04

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? If so what can I about the Linux crashes? regards Shlomo Kut Software Engineer MKS Instruments Tenta Products Tel: 972-8-9181015 Fax: 972-8-9181020 www.mksinst.com

If so,pls check your boot command in YOUR_BOARD.h.U-Boot use "bootm" command RATHER THAN "go" command to boot LINUX kernel. > > Hit any key to stop autoboot: 0 > > ## Starting application at 0x01600000 ... > > undefined instruction Hope this hope.

[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

Dear Friends, Anyone has already worked with this device trying to use U-boot as bootloader? I have a board using this device (is an ARM720TDI) and I would like to use U-boot to load uClinux Image. Any suggestion would be apreciated, Thanks Gianfranco

[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
by Rune Torgersen 01 Mar '04

> 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 :)

Re: [U-Boot-Users] bootp

A bit more info -- it looks like the correct file name is sent in the dhcp request, but then u-boot switches to tftp mode with the incorrect file name in the request. I have placed the capture file here: http://www.lambdaaccess.com/u-boot.libpcap thanks again for your help. > I captured some packets using ethereal and I see the request to the > bootp server contains the wrong file name.
