Hi jigdo,

Please post the result of the imi command for your u-boot kernel image. E.g. if your compressed

kernel image is at address 0x00200000:

==> imi 200000

And post the result of a mkimage list. E.g. if your image file name is kernel.img:

$ mkimage -l kernel.img

It looks like an endian order problem. Did you build the mkimage utility yourself, or are you

using the pre-built version from psyent.com?
