Hi Srikant,
In my system, i have something like this,
# ls -l /sys/class/mmc_host/mmc1/
lrwxrwxrwx 1 0 0 0 Jan 1 00:00 device ->
../../../MMC
drwxr-xr-x 4 0 0 0 Jan 1 00:00 mmc1:bf0a
drwxr-xr-x 2 0 0 0 Jan 1 00:00 power
lrwxrwxrwx 1 0 0 0 Jan 1 00:00 subsystem ->
../../../../class/mmc_host
-rw-r--r-- 1 0 0 4096 Jan 1 00:00 uevent
# ls -l /sys/class/mmc_host/mmc0
lrwxrwxrwx 1 0 0 0 Jan 1 00:00
/sys/class/mmc_host/mmc0 -> ../../devices/EMMC/mmc_host/mmc0
#
#ls /sys/devices/platform
it shows uevent and some other components specific to my platform and no MMC
components.
But i have something like this,
# ls /sys/devices/MMC
driver irq0 power subsystem
id mmc_host resource uevent
# ls /sys/devices/MMC/mmc_host
mmc1
# ls /sys/devices/MMC/mmc_host/mmc1
device mmc1:bf0a power subsystem uevent
That is why i have choosen the media path in vold.conf as below:
## vold configuration file for the emulator/SDK
volume_sdcard {
## This is the direct uevent device path to the SD slot on the device
media_path /devices/MMC/mmc_host/mmc1
media_type mmc
mount_point /sdcard
ums_path /devices/platform/usb_mass_storage/lun0
}
Please let me know if this is not fine.
Regards,
Sreedhar
