I would like to ask what is the reason to NOT support to boot from NAND on cubietruck. Several years ago it worked out ok. I/O speed is not important for me, but i remember some armbian developers commented it is not supported anymore because it is too slow. I do not use my cb3 for speed, but for stableness.
When booting from NAND is not supported on modern u-boot/linux, why does it work on my NanoPI Neo Plus2?
