[U-Boot] mx7: ums command does not mount SD card partitions

[Ye Li]

Hi Fabio,

   I just tried 'ums' on mx7d sabresd with latest u-boot-imx codes. It works well on my board. I don't see your issue. My SD card has a FAT partition. I can access it from my host after running the "ums 0 mmc 0".

Best regards,
Ye Li

Hi Peng/Ye Li,

We are trying the 'ums' command on a mx7d sabresd board running the latest U-Boot code from u-boot-imx tree:

=> ums 0 mmc 0

This should make the content of the SD card to be mounted on the host PC and the two SD card partition should pop up in the screen.

We do see the two partitions icons to appear on the host, but the two SD card partitions are not mounted automatically.

We see this behavior on a mx7d sabresd and also mx7s warp boards.

In other mx6 boards the partitions are correctly mounted.

We also tested the following command in the kernel on a mx7d sabresd:

modprobe g_mass_storage file=/dev/mmcblk0

and the SD card partitions are always automatically mounted.

Any ideas as to why U-boot ums do not mount the SD card partitions automatically?

Thanks,

Fabio Estevam
