kernel image in SDRAM but not booting?

Hi scott:

I use the u-boot-1.1.3 downloaded from www.souceforge.net

I see the readme the mkimag command used as fellow:

mkimage -A ppc -O linux -T kernel -C gzip

-a 0 -e 0 -n "Linux Kernel Image"

-d linux.bin.gz uImage

I think the uImage file also is .bin type file,so I use bin2flash comand convert the uImage to uImage.flash,then download to .flash file use nios2-flash-programmer .

I don't have the .img file.

>It looks like an endian order problem

I am sure the niosII is little endian,because in the vmlinux.lds file , "OUTPUT_FORMAT("elf32-littlenios2", "elf32-littlenios2", "elf32-littlenios2")"

Best Regards
