I have a tinkerboard s, it was standing in a corner and according to who used it, it worked normally via sd card (note, they didn't know about the existence of emmc), when I tried to use it with a new sd card, in most of the OS I tested it crashed right on the first screen with the exception of an android system that turned on for a while but when restarting it would reach the start screen and keep flashing the screen without me being able to touch anything, on the emmc the computer I have recognizes TBS as unknown device.
I'm sorry if there are English errors because I'm using the google translator.
