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.
