Hi
Im trying to get the libertas driver working for the sd8686 SDIO
module on MMC2 of the beagleboard. It fails with error -110 ( mmc1:
req done (CMD52): -110: 00000000 00000000 00000000 00000000 )
What could be causing this? I'm quite new to kernel/driver programming
so excuse me if my problem is silly.
Kernel: 2.6.35.5
Firmware: 9.70.3.p24
Below is the log with MMC debug enabled:
