Did you try to boot from sdcard ? I am not able to boot my board from
sd-card without this change. As I mentioned earlier in my email
to buildroot mailing list, with mmc debug enabled I see that mmc
tries to init sd-card when I remove it from the slot.

Maybe there is a minor differences between h/w versions or batches ?
What is you board version ? I tested on board v1.0.

Regards,
Sergey
