I have a headless Orange pi 3 and wanted to be able to test a new install.
Is it possible to issue a specific reboot command that will switch to boot from one storage to the other storage?
I have armbian bionic installed and running on the EMMC.
and
A new bionic build installed on a new SD card.
So, if i'm tinkering with the new build on the SD card, can i reboot to the EMMC without removing the SD card, and then similarly reboot from the EMMC into the SD card build??
