[U-Boot-Users] PATCH - Fix oob data copied into supplied buffer
by Troy Kisky 21 Apr '08

21 Apr '08

This patch correctly sets the oobavail variable and fixes a bug where the oob data was not valid when there where multiple groups in oobfree. It also defines a new variable so that you can tell which parts of a large page have ecc errors.

[U-Boot-Users] U-Boot WinCE booting support?
by Stefan Roese 19 Apr '08

19 Apr '08

Hi, I'm wondering what may be needed to boot WinCE (6.0) images from U-Boot. Searching the web leads to some pages that mention booting WinCE is possible. But my understanding is that some additional patches are necessary and the official U-Boot doesn't support this currently. Does anybody have experience with this? Any hints appreciated. Thanks.

[U-Boot-Users] [patch] disable caches before booting an app for Blackfin apps
by Mike Frysinger 14 Apr '08

14 Apr '08

It isn't generally save to execute applications outside of U-Boot with caches enabled due to the way the Blackfin processor handles caches (requires software assistance). This patch disables caches before booting an ELF or just booting raw code. The previous discussion on the patch was that we wanted to use weaks instead, but that proved to not be feasible when multiple symbols are involved, which puts us back at the ifdef solution. I've minimized the ugliness by moving the setup step outside of the main function.

[U-Boot-Users] [PATCH] add support for Toradex Colibri module
by Daniel Mack 14 Apr '08

14 Apr '08

Hi, this patch adds basic support for Toradex PXA27x based Colibri module. It cleanly applies on u-boot-1.1.6. However, I didn't manage to get the flash to work at all, at boot time, I always get the message "Flash: 0 kB". I'm new to the U-Boot environment, so maybe I missed same essentials here. Also, the DM9000 driver does not seem to be able to correctly read its MAC address on this platform. I've read some mails about similar behaviour. Is there any patch going upstream soon? For now, I helped myself by hacking a fake MAC to bd->bi_enetaddr right before initialization but that's of course not a solution. Thanks and best regards, Daniel

[U-Boot-Users] [Patch] Disable icache before call the first line of kernel in do_bootelf().

On some architecture, it is not save to call the first line of kernel without disable the instruction cache.
