How do we get the EMAC driver (or another ethernet driver) in the ucLinux build? I only see options for some of the drivers when we run menuconfig.
We are also going to try and connect the opencores.org ethernet mac.
Thanks, Tom

I have some problems to get the EMAC going. Just adding the EMAC to the project and assigning the parameters and the pin assignment I can access the EMAC with simple commands and read/write to the register. However, I never see the link LED come on when I connect the cable. I read the control regiser and the physical interface is supposed to be enabled.
At least for revision 1, the ethernet PHY on the P160 module behaves quite strangely. When I connect to a 10mbps link, I only get the link LED, never the activity LED, even when many packets are going. Then, when I connect to a 100mbps backbone, all 3 leds glow solid...
But anyway, returning to your question- yes the Link LED should glow.
What happens if you query the PHY MII registers via the EMAC? I forget the register offset, but it's in the EMAC datasheet. You pass in a 5 bit (0->31) MII register and a query command, and it returns PHY status info.
Do you plan to post the updated platform or could you sent it to the list?
Yes, I will post mbvanilla_net - I'm at home now, but will do so tomorrow when I return to work.
Regards,
John
