Hi,
I am new to U-boot, please say if i am wrong ,
on my custom board i am using mpc862 and using scc1 as my ethrnet port its works fine,
i have scc3 for ethernet also, in linux kernel i changed the configuraton file to change to use scc3 , i see nothing happening,
is it because in uboot i have enbaled scc1 and enabling scc3 in linux kernel so not working ?
i dont think this should be the problem as linux kernel resets the CPM,
i am must be able to use scc3 on linux,
any ideas please throw some light .
anyone has enabled scc3 on uboot for mpc862 , i dont find any code reference , what things i need to change , ?
Thanks IN Advance

Then obviously your configuration in the Linux kernel is broken.

inux,
If you configure the correct values in the Linux kernel (port pin assignments, clock routing, eventually setting of BCR's etc.) it should work.
