??? This is why I always like to review the scripts/makefiles ;-)

Time to go back to the basics ...

1. Please post an objdump of the elf headers. E.g.: $ nios2-elf-objdump -h vmlinux

2. Confirm that the elf image can be loaded and successfully run using nios2-download.

3. Use the elf image to create a binary (nios2-elf-objcopy -O binary). Load the

binary (via nios2-console) to the load address, set the pc to the load address,

then resume execution -- confirm operation.

4. Make the u-boot image with the binary (uncompressed) -- confirm operation.

5. Compress the binary, and make the u-boot image (compressed) -- confirm operation.
