u-boot on mbx860

[Rod Boyce]

My guess would be RAM unitisation is not correct in U-boot.  What
configuration is your MBX board?  If you transfer the kernel image into two
separate locations on your board and do a memory compare are both images the
same.  If you download the image back to the PC and do another memory
compare are the images still the same?

This is where I would start.

Regards,
Rod Boyce.
