Yes I have, GPIO(12-25 to alternative 1 INs and OOUTs). I also have set up SDR0_CUST0[MEN]. But I'll look over it again.
Thanks for the tip.

Do you have the pins setup properly. They default to tri-state gpio and need to be setup as ethernet pins.

Hello!
I've managed to port U-boot for our board with a 440EP processor. But I have problem to get the ethernet working. We use a Altima AC104Z PHY. I can read out all PHY register and they seem to be correct. I have tried both RMII mode with the 405gp_enet.c and SMII mode with the 440gx_enet.c implementation.
The PHY initiation looks fine. But when trying to ping or tftp I get no connection.
I can see that I enter the eneInt interrupt handler.
If anyone has a hint or tips on any diffrences on the 440EP regarding ethernet please let me know.
Below I send the serial output from a SMII run.
Best regards,
Jacob.
