[U-Boot-Users] SCC3 ethrnet port on PMC862
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 Somshekar

Then obviously your configuration in the Linux kernel is broken.
is it because in uboot i have enbaled scc1 and enabling scc3 in linux ke rnel so not working ?

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