Not all OSes you install to your eMMC allow you to easily boot a different OS from the sd card.
You should carefully read (and understand) the "boot order" part in the wiki.
From the factory installed OS your boot order is actually written on the eMMC, this tells your board to boot from the sd card first, "IF" one is in the slot.
But not all OSes you install will have this 'order' built into their software.
Can you point out the wiki page with that info?
I'm looking at https://wiki.pine64.org/index.php?title=...structions and the very last section ("Reuse SD card for data storage...") says "the Allwinner firmware in the PinePhone uses some (normally) unused space at the front of the SD card to store boot software". That implies that there's firmware (not on the eMMC?) that looks at the SD card first.
But that's not 100% clear, so I'm wondering if there's another wiki page that I missed.
