I'm trying to setup a new u-boot on an old STx AMC8548 board. I discovered the reason for instability I reported earlier, namely DDR's twoT_en option was not set. However, now I have a different problem.
Attempt to access the network always fails with "Got error 4" message. I can see ARP requests being broadcast to the network but nothing else happening.
The link speed is 100Mb.
