Hi:

I used u-boot-1.0.2 to boot linux.My target board is ALTERA DK1C20 and cpu is nios.I used tools/mkimage to encapsulate a linux kernel image with header information.But it display some error messages,it like that:

 

[root@a901 u-boot-20040316cvs]# tools/mkimage -n 'linux kernel' \

> -A nios -O linux -T kernel -C none -a 1010000 -e 1010000 \

> -d /opt/cdk4nios/src/u-boot-20040316cvs/linux.bin uimage

 

Invalid CPU Type - valid names are: alpha, arm, x86, ia64, mips, mips64, ppc, s3 90, sh, sparc, sparc64, m68k

 

Because my cpu is nios,so my linux kernel can't boot.

 

 

I try follow patch.

When I boot linux image to my target board, it have error messages.

Like that:
