I also had run ins with their Pine A64 LTS. You can buy eMMC cards that fit on the board. Their documents say you can boot from them. Like 10x performance of a mSD card and less wear-out. I use a USB device to make the drive mountable from a Linux box, and copy the firmware as prescribed. I then unmount and load in the A64, and.... NOTHING. Supposedly there's a uboot command that maybe enables it. Or maybe its autodetect. Or maybe (5 other ideas, that all fail). I returned that shit too because they make claims that it works these official ways, and it never does. Pine is a parasite. Always has been, but they make-pretend that they're some great FLOSS company.
