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

[U-Boot-Users] Hush 'elif' operation?
by Robin Gilks 12 Apr '04

12 Apr '04

Greetings I'm trying to get as close to a switch statement in hush shell language as possible and thought that a set of if/then/elif/else would be tidier than nested if/then/else. It doesn't work how I expected however. The example below illustrates the problem - I was expecting execution after a true test (in the first 'if' in this case) to continue after the 'fi' but instead it ploughs through all the other executable (echo) statements having skipped the elif statements. It does correctly skip the else clause however :-)) Could someone assist in the navigation of this module to point out where would be a good place to start (i.e. some basic principles and assumptions of how the parser works).

[U-Boot-Users] Patch: Support for PQ27e (8247/48/71/72) chips and MPC8272ADS board
by Yuli Barcohen 23 Mar '04

23 Mar '04

Hi, This patch adds support for the newest additions to Motorola PQII family (MPC8247/8248/8271/8272) known also as PQ27e. They've got different DPRAM layout (as was discussed on the list) so common files were changed. I tested the code on several boards I've got (using both old and new chips). Motorola released new derivative of MPC8260ADS evaluation board supporting these chips: MPC8272ADS. This patch adds support for the new board. -- ======================================================================== Yuli Barcohen | Phone +972-9-765-1788 | Software Project Leader yuli(a)arabellasw.com | Fax +972-9-765-7494 | Arabella Software, Israel ========================================================================

[U-Boot-Users] small AT91RM9200 patch

Hi there, to make porting U-Boot to new AT91RM9200 based boards easier I suggest the small attached patch. * Patch by Steven Scholz, 20 Feb 2004: - some cleanup in AT91RM9200 related code PS: a) The patch adds the configuration setting "CFG_AT91C_BRGR_DIVISOR" which is only AT91RM9200 specific. Should I provide a patch for README or rather create a doc/README.at91rm9200? b) Should we do some white space cleanings REDAME's "Directory Hierarchy" section?

[U-Boot-Users] get_ticks() for AT91RM9200
by Steven Scholz 15 Mar '04

15 Mar '04

Hi there, as mentioned before the AT91RM9200 port was missing a get_ticks() function. I made a lot of white space fixes as well because now the similarities _and_ differences with other ARM implementations are more obvious when doing a "diff". I added get_ticks() because it was needed by the NFS implementation. However it looks like get_ticks() is hardly use in U-Boot. I think get_timer() is used in most cases... CHANGELOG: * Patch by Steven Scholz, 27 Feb 2004: - Adding get_ticks() and get_tbclk() for AT91RM9200 - Many white space fixes in cpu/at91rm9200/interrupts.c Thanks, -- Steven Scholz imc Measurement & Control imc Meßsysteme GmbH Voltastr. 5 Voltastr. 5 13355 Berlin 13355 Berlin Germany Deutschland
