Using the uSD on BeagleBone Black as Aux Storage

I followed some instructions, that I have since lost track of, to enable the use of the uSD card on the BBB for auxilary storage when booting from the internal eMMC.   The below are my version of what was needed:

Format the drive

Add a partition and make it of type FAT, name it and size it however you want

After it has been formatted and partitioned mount the FAT 32 partition you just made

Create the document "uEnv.txt" in the root of the partition and add the following lines to it:

mmcdev=1

bootpart=1:2

mmcroot=/dev/mmcblk1p2 ro

optargs=quiet

This should do it.
