long shot really, but does anyone have a working executable mkimage for DOS or a dos window in windows (don't flame me for using windows !!)

[U-Boot-Users] Binary file cat
by Adam Bezanson 03 Aug '04

03 Aug '04

Hi, I have ported u-boot to my arm920t based system. I have a unique situation in that my processor requires a binary header to be placed In front of u-boot.bin before it is burnt into flash. If the processor doesn't find this header in flash it will not boot out of flash. Currently I have the header file as a separate file in the root directory and when I finish a new compile I have a shell script which Simply does a 'cat header.bin u-boot.bin > out.bin'. I'd like to get away from this and add it to the Makefiles so for my board I don't have to run this script every time. Before I go editing a top-level Makefile, I wanted to ask for advice on how I should go About doing this? Anything I can do in my board-specific directory would make me feel better. Suggestions? Thanks, Adam

I was trying to load linux-2.4.4 in FADS860T board using u-boot-1.0.0. I have settted environment variables like ipaddr,serverip,ethaddr,bootargs bootfile and saved the environment. Then,i typed tftpboot to download image from server. Then,i typed bootm to start the booting process. System is stucked by showing "Uncompressing Kernel Image ... OK" sequence of these events r given below.can u please suggest, what i need to do to come out from this. Thank you.

[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] fix the ARM memory layout
by Anders Larsen 08 Feb '04

08 Feb '04

Hi, here's a fresh version of my rather intrusive patch from the 17.th sept. to rearrange the ARM memory layout to bring it in line with the README. This has the positive side-effect of actually allow U-Boot to run on PXA- and IXP-based targets; the current implementation sets up the heap using bogus addresses causing u-boot to crash (this even applies to the recently added board "ixdp425"). This patch doesn't go all the way, though, since doing away with the board-specific setting of TEXT_BASE would require the code to be position-independent, which at least the cpu initialization code in cpu/*/start.S is _not_. CHANGELOG: Bring the ARM memory layout in line with the documentation. Cheers Anders

[U-Boot-Users] [PATCH] pass custom data to Linux
by Anders Larsen 02 Jan '04

02 Jan '04

Hi, the attached patch defines a new config option CONFIG_CUSTOM_TAGS for ARM targets. Defining this option causes do_bootm_linux() to call the function setup_custom_tags(), which should be supplied from the board-specific stuff. Specifically, I need to pass the board revision and serial number to the Linux kernel, and I'd like to use the standard method of passing tagged parameters. For my purpose, ATAG_SERIAL and ATAG_REVISION are already defined (and supported by the kernel). CHANGELOG: add config option CONFIG_CUSTOM_TAGS Cheers Anders

[U-Boot-Users] IDE patch
by Pierre AUBERT 08 Dec '03

08 Dec '03

Hi everybody, The attached patch makes the IDE and FAT commands working on our custom board. CHANGELOG: * adds a return value for the fpga command * fixes an endianess problem in fat.h * adds an ide_preinit function called in ide_init if CONFIG_IDE_PREINIT is defined. If the ide_preinit fails, the ide_init is aborted. * adds the CFG_ATA_STRIDE configuration variable, which defines the spacing between ATA registers. The default value is 1, but it can be modified in the board configuration file.
