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)
