Well I stopped building and actively supporting the legacy image. The only missing thing is the NAND driver, for all other uses mainline kernel should be better.
when you run the multitool, did it prompt you a message mentioning that box your using is using NAND chip, if it does then you need to use legacy images which can be found here. You can only run later latest images via SD card or via USB with NAND bootloader upgrade.
and even if you try flashing non-legacy image on NAND system, it will just error out during early boot process mentioning it cant mount something.
to be honest if you have a NAND model, you might as well just use the SD card slot to run armbian.
