Unable to mount eMMC on T1024RDB.

Hello Team,

I am using a T1024RDB processor for our project. I can create partitions on eMMC successfully, but I am unable to mount them to the user space.

The partition table looks as,

*********************************************************************

Disk /dev/mmcblk0: 13.8 GiB, 14763950080 bytes, 28835840 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x17be4acf

Device Boot Start End Sectors Size Id Type
/dev/mmcblk0p1 2048 3048 1001 500.5K c W95 FAT32 (LBA)
/dev/mmcblk0p2 4096 5098 1003 501.5K 83 Linux

Command (m for help):

*********************************************************************

Below is the error observed when trying to mount.

**********************************************************************

root@t1024rdb:~# mount /dev/mmcblk0p1 /mnt/temp
mount: wrong fs type, bad option, bad superblock on /dev/mmcblk0p1,
missing codepage or helper program, or other error

In some cases useful info is found in Syslog - try
dmesg | tail or so.

**********************************************************************

Request your support at the earliest.

Thanks in advance,

Kasturi.

Please try command

# mount -t vfat /dev/mmcblk0p1 /mnt/temp

If it still doesn't work, please try the following command.

# mkfs.vfat /dev/mmcblk0p1

# mount -t vfat /dev/mmcblk0p1 /mnt/temp

Thank you for the reply yipingwang,

I tried the commands you suggested, but still, it did not work for me.

Below is the log for your reference.

--------------------------------------------------------------------

root@t1024rdb:~# mkfs.vfat /dev/mmcblk0p1
root@t1024rdb:~# mount -t vfat /dev/mmcblk0p1 /mnt/
[ 116.031339] FAT-fs (mmcblk0p1): codepage cp437 not found
mount: wrong fs type, bad option, bad superblock on /dev/mmcblk0p1,
missing codepage or helper program, or other error

In some cases useful info is found in Syslog - try
dmesg | tail or so.
root@t1024rdb:~#

It says codepage not found, But it is enabled in the kernel menuconfig, attached is the screenshot for your reference.

Thank you,

Kasturi.
