Why FEC and SCC1 can not work at the same time?

[Ricardo Scop]

Zhongqx,

Probably there some is initialization missing/misconfigured both in FEC
and SCC enet drivers for your board. Main candidates are I/O pins
configuration and/or clock selection.

HTH,

It might look like I'm doing nothing, but at the cellular level I'm
really quite busy.
