Hi Joakim,

I have tried it but it doesn't work.

Just now found that with single ' quotes the entire sequence it works.

quoted

Setenv set_mac 'cp 0xffec0000 0x100000 1024;fdt addr 0xc00000 8192;fdt set /soc8272@f0000000/ethernet@24000 mac-address "[00 44 00 55 00 66]";erase 0xffec0000 0xffec4000;cp 0xc00000 0xffec0000 1024;bootm 0xfe060000 - 0xffec0000'

quoted

run set_mac

For the above command I want to replace the mac address with the ethaddr> How do I do that. I tried $ethaddr but I get extra : characters.

Of course you do, ethaddr has a different syntax and contains :

Anyway you should not have to set mac address manually like you do, u-boot will do it for you if you
have configured u-boot correctly and have a proper dtb tree. Check the u-boot code and the many dts files in linux
under arch/powerpc/boot/dts
