Subject: [U-Boot-Users] FEC problems on mpc852
Date: Tue, 12 Aug 2003 15:13:52 +0100	[thread overview]
Message-ID: <3F38F620.4060207@2net.co.uk> (raw)

Hi,

I am having some problems getting the FEC to work, perhaps someone on 
the list has seen something like it and can help me out?

The problem occurs in fec_send (in cpu/mpc8xx/fec.c): the 
BD_ENET_TX_READY bit is set but never cleared, indicating that the 
packet is ready to send but the hardware is not processing it. The 
receive side works fine: packets are received and processed as expected. 
So, I do not suspect the physical path to the outside world. Anybody any 
ideas what could cause this sort of behaviour? Any known problems with 
the 852T? What can I look at to find out what is going on? By the way, 
this is on u-boot 0.4.4.

Best regards,
Chris Simmonds
