Re: [microblaze-uclinux] Ethernet update for David Banas' NuHorizons board project
FYI - I'm working on a board that's using a 44MHz system clock and
Ethernet is working at 10Mbps. To get it working ... I hacked up the
Ethernet driver to force 10Mbps-only mode and then triggered a
re-negotiation with its link partner. Worked OK after that.
Also had some problems with it auto-detecting the PHY address properly.
Sometimes would detect the PHY at 0x1, 0x2, or 0x3. Hard-coded the
address with the appropriate value for my board (0x3)
