I have two strange problems with uboot-1.1.1 on my AT91RM9200DK.

1) It will not pass the "uncompressing image" stage from power up, but if I remove the "Boot mode select link", press reset, replace the link, press reset, the system will begin to boot.
This is not necessarily an u-boot issue. To me it looks more likely to be that the loader.bin by atmel do not initialize the CPU properly before loading the zipped u-boot.
I compiled a new version of the boot.bin file provided by Atmel and it boots the old version of uboot (0.3.2) with no problems. i.e. I don't need to play with the "boot mode select link" to make it work like I do with uboot-1.1.1. There must be some changes between uboot-0.3.2 and uboot-1.1.1 that have caused this problem.
output:
<press reset>
boot 1.0 (Aug 2 2004 - 12:12:24)
Uncompressing image... done!
starting application
U-Boot 0.3.2 (Jun 24 2003 - 17:04:08)
