uboot + uclinux + nios2

I compiled uboot as well as uclinux for stratix board DK1S40 using standard hardware design for nios2 that comes with web addition software from altera. 

 

when I tried to create an uImage ...running this command. 

 

./mkimage -A nios2 -O linux -T kernel -C gzip -a 0x01000000 -e 0x01000000 "uclinux kernel Image" -d linux.bin.gz uImage 

 

I got an error message........ 

 

Invalid CPU Type - valid names are: alpha, arm, x86, ia64, m68k, microblaze, mips, mips64, ppc, s390, sh, sparc, sparc64 

Usage: ./mkimage -l image 

-l ==> list image header information 

./mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image 

-A ==> set architecture to 'arch' 

-O ==> set operating system to 'os' 

-T ==> set image type to 'type' 

-C ==> set compression type 'comp' 

-a ==> set load address to 'addr' (hex) 

-e ==> set entry point to 'ep' (hex) 

-n ==> set image name to 'name' 

-d ==> use image data from 'datafile' 

-x ==> set XIP (execute in place) 

 

 

when I looked at the mkimage source code file....I found the nios2 stuff is missing....... 

 

 

I would really appreciate if someone help me to resolve this issue. 

 

 

Is anyone knows ......what needs to be done in order to create an uImage for nios2 platform.

Hi haq,

You need to get the latest version of tools/mkimage.c (revision 1.15). 

You're probably using mkimage revision 1.14 (from the u-boot 1.1.2 tarball).  

Download this file from sourceforge & rebuild. 

 

Otherwise, you can get a pre-built version of mkimage from:
