BeagleBone Black using MicroSD for extended storage

Hi everyone,

I was wondering if there is a clear-cut way to make a microSD card extended storage for the BBB. I would like to boot from eMMC, if possible (for quicker boot up), and have a microSD setup for extra storage. The microSD card I have is 16GB and I am currently running the iot version of 9.5. Thanks in advance!

Mount it somewhere in the file system, format it (or does one have to format first – you’ll likely want it to be in ext3 or ext4 rather than native FAT32 so Linux protection and modes are active). Depending upon what you need storage for, you might move all of /home to the SD card, or partition it for /home and /var, and mount those partitions over the original.

You’d want to make the mounting operation automatic via lines added to the fstab file. Maybe need to set privileges so user accounts can access.

debian@beaglebone:~$ cat /etc/fstab

/etc/fstab: static file system information.
