Hi,

how can I read from FEC Receive FIFO Data Register (FECRFDR) without using DMA. Everytime I try to access this FIFO I get RFERR and my FEC stops. My DMA code (better the RTEMS code) crashes after a view minutes. So i will try to write a simple and stable polling driver.

 

I'm using a costum MCF5475 board.
