timeout while detecting SD card

[Björn König]

Hello,

yet another problem. I can't access the SD card. I googled a bit and
noticed that I'm not the only one with this problem, but I haven't found a
solution yet. Here are some details:

Everything seems to work fine until sending the app command in
mmc_wait_for_app_cmd. The driver gets an interrupt with a "response
time-out error" set in status register. That's it.

I tried to find the problem and executed an Atmel MCI demo programm in
kernel shortly after mmc_scan. It does basically the same and detects the
card in the SD card bay properly. There is one obvious difference: the
demo doesn't use an interrupt service routine.

I hope someone has a hint for me, once again. ;-)

Björn
