Compute Module • Re: Using eMMC as MSD after booting from NVME

I was able to mount the eMMC disk after all.

I tried the "New Partition UUID" but the eMMC disk was not automatically mounted. I was hoping it would be automatically mounted the same way that the NVMe disk is automatically mounted when booting from eMMC.

So I cannot say the UUID mattered at all. However, I could manually mount the eMMC storage manually.

First, find the device for the partitions you want.

Code:

$ sudo fdisk -l (lowercase el)
The output should include the eMMC devices in a "df -H" style table. My CM5 listed a bunch of devices, but I looked for the listing for the eMMC disk. The table looked something like the following. Note the size of each partition to help find the right one.

Code:

/dev/mmcblk0p0 FAT32 512M/dev/mmcblk0p1 linux  28G
Then to mount the mmc partition you want in the same was as the automatic mount would, run these commands but insert the partition device on the mount command.

Code:

$ mkdir /media/emmc$ sudo mount /dev/mmcblkp1 /media/emmc
Last, when you want to unmount it, run these commands.

Code:

$ sudo umount /media/emmc$ sudo rmdif /media/emmc
