[U-Boot-Users] FEC on MPC852T, TX problem, need help

[raymond yang]

Hello,
 
The issue I met is, FEC on MPC852T
 
- TX doesn't work. The TX_EN  is always low level, although data sent out from FEC to PHY
 
- RX could work, interrupt generated, package received, looks fine.
 
I have two board, both are the same cases. Can anybody give some hints? Thanks!
 
Generally speaking, RX might be harder to be debugged than TX,  but this time, things becom completely different. RX could work, but TX doesn't work.
 
Best Regards
Raymond
