Hi,
I tried enabling MMC support in Android kernel menuconfig as shown below for camera application
SCSI Device Support → Proble all LUNS on each SCSI device
USB Support → USB Mass Storage Support
and more n’t exactly sure. For your reference i have attached my .config as ConfigMMC
after enabling i’m able to see MMC Card being detected which is connected to beagle board via USB Card Reader.
The kernel messges is see is listed below

after this i tried mounting this sd card “mount -o rw -t ext3 /dev/block/sdc2 sdcard/”, it mounted properly and i’m able to see all contents inside folder named “sdcard”. But the Android application is still asking me to connect sdcard when i try running camera application. This SD card is not even visible in Android settings too. Pls guide me to make camera app running properly on BeagleBoard.
Thanks,
Suresh Kalidasan.
