Hi,
I was trying to mount the filesystem from MMC card on OMAP3EVM.
Came across this oops.
However, when I boot via ramdisk/NFS and mount /dev/mmcblk0p2; there is no oops.
Anything missing in the configuration?
Here is my snapshot menuconfig:
--- MMC/SD/SDIO card support
*** MMC/SD/SDIO Card Drivers ***
<*> MMC block device driver
[*] Use bounce buffer for simple hosts
<*> TI OMAP High Speed Multimedia Card Interface support
Also:
# git-show --pretty=oneline
5019ed843f3208482c64043e4052e89b3d5462a0 sync isp1301_omap with mainlne
Best regards,
Sanjeev
