出现错误：

出现错误：

执行修复命令：

fsck.vfat -V /dev/mmcblk0p1

EMMC_S_FUNC_DD_RW_QUICK source "common.sh"; install_modules.sh "emmc"; do_cmd blk_device_dd_readwrite_test.sh -b "1M" -c "10" -d "emmc"

没有-f fstype选项，所以在blk_device_prepare_format.sh中，

if [ -n "$FS_TYPE" ]; then
    test_print_trc "Erasing/Formatting this partition and then mount it"
    do_cmd blk_device_erase_format_part.sh -d "$DEVICE_TYPE" -n "$DEV_NODE" -f "$FS_TYPE" -m "$MNT_POINT"
    do_cmd blk_device_do_mount.sh -n "$DEV_NODE" -f "$FS_TYPE" -d "$DEVICE_TYPE" -m "$MNT_POINT" -o "$MNT_MODE"
else
    test_print_trc "Mount the partition with the existing FS on device"
    do_cmd blk_device_do_mount.sh -n "$DEV_NODE" -d "$DEVICE_TYPE" -m "$MNT_POINT" -o "$MNT_MODE"
fi

 没有执行

EMMC_S_FUNC_DD_RW_QUICK pass

后面几个testcase就fail了。
