I was able to mount the card without knowing the type, apparently mount is smart enough to determine on its own.

Not arguing, as you certainly are correct. Can a system running an older version from eMMC be used to boot from the SD card, requiring a read of the older format uEnv.txt?

It required that I do some research to fully understand your response, so I learned even more. I had assumed it was a separate partition on the SD card, exposed by the USB client. Now I see that there is only one partition on the SD card, and these "file systems" presented by the USB interface are just image files, which themselves can be mounted (if you know the magic, i.e. starting sector). I never tried to modify this content when accessed through USB - I didn't realize it is read-only.
