Seems like that was the trick. After removing the breakout board it works much better.
I still got some problems which I don't know if its software related. Sometimes when I power on the board the ethernet LEDs does not turn green and the network does not work. If I power cycle the board a number of times the LEDs turn green I can can use the network. Do you know if that might be hw related or may it be something with the initialization? I'll try to test U-boot v2 as you are using and see if it works better. /Johan 2009/6/15 Eric Lammerts <u-b...@lists.lammerts.org>: > On 06/15/09 10:01, Johan wrote: >> I have trouble using your patch together with our LogicPD iMX27 >> Litekit.
