I have an arm-corex AM1808 (TI OMAPL-138/DAVINCI) cpu based board, using Micrel KSZ8031. .....

Sending discover... Sending discover... No lease, failing Adjusting output audio levels ... It says no lease. But i verified that even setting a fixed ip, board is not reachable. Tracing inside phy.c i don't see the link to come up. Nothing seen on WS. As far as you know, there can be some bug open for davinci-emac and micrel ?
