Cannot identify SD card partition! (mmcblk0: unknown partition table )

Situation :

When I  plug-in my SD card into some EVB board.

SD driver can detect mmcblk0, but cannot detect SD partition.

like below:

# mmc0: new high speed SDHC card at address f7c1

mmcblk0: mmc0:f7c1 SD08G 3.50 GiB

mmcblk0: unknown partition table

 

But if I want to mount SD card to some folder,

I'll need to identify partition of SD card file system.

 

Solution :

After tracing...

Only need to enable CONFIG_MSDOS_PARTITION of kernel config.

then, the partition will be identify!!

# mmc0: new high speed SDHC card at address f7c1

mmcblk0: mmc0:f7c1 SD08G 3.50 GiB

mmcblk0: p1
