I can't test that at the moment as I can only boot from MMC as there's currently no support for MMC booting in the mainline kernel. So ... the code works for you, but not for me. I guess the other difference is that I'm not using the same PHY (we use a 10/100 SMSC 8710A, not the GbE Atheros part). Could that make any difference ? Markus, are you still seeing the same issue ? What PHY are you using ? Cheers Mark J.
