https://wiki.t-firefly.com/en/ROC-RK3568-PC/01-bootmode.html
Есть 2 режима для записи eMMC - RockChip USB mode и Maskrom USB mode:
- RockChip USB mode
- работает, если работает bootloader и SARADC0 == 0 ????
- Maskrom USB mode.
- работает, если ничего не работает, и D0 (или Clock) bootmedia закорочен на землю
