Hello Bruce,

I used u-boot-1.1.1 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.Can you tell me what can i do?

Ps:my name is Bruce

Hm, I haven't worked with a NIOS system, but obviously the port forgot to include support in the mkimage tool. cmd_bootm.c tests for those values so that might be your problem. Try the attached patch and maybe some NIOS people on this mailing list can speak up.

Cheers Detlev
