## Example of a standard sdcard mount for the emulator / Dream
# Mounts the first usable partition of the specified device

#dev_mount sdcard /mnt/sdcard auto /devices/platform/sdhci-pxav3.0/mmc_host/mmc1

#modify by wangxianshan for mount sdcard 2013.3.6

dev_mount internal_sdcard /mnt/sdcard 19 /devices/platform/sdhci-pxav3.2/mmc_host/mmc0 ums_file_path /sys/devices/platform/mv-udc/gadget/lun0/file nonremovable|asecinternal

# dev_mount right_sdcard /sdcard2  auto /devices/platform/goldfish_mmc.1 /devices/platform/msm_sdcc.3/mmc_host/mmc1

## Example of specifying a specific partition for mounts
# dev_mount sdcard /sdcard 2 /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1

#dev_mount internal_sdcard /mnt/sdcard 24 /devices/platform/msm_sdcc.1/mmc_host/mmc0 ums_file_path /sys/devices/platform/msm_hsusb/gadget/lun0/file nonremovable
#dev_mount        external_sdcard        /mnt/sdcard/external_sd auto /devices/platform/msm_sdcc.3/mmc_host ums_file_path /sys/devices/platform/msm_hsusb/gadget/lun1/file asecallowable
