ROC-RK3399-PC Board Boot Media Detection Sequence

This is not the boot sequence of u-boot bootloader! This is the boot sequence of the board SoC.

  1. SPI
  2. eMMC
  3. MicroSD
  4. USB OTG

Please note that if you flash a partial or bad SPI image, the device might get bricked until the SPI is re-flashed. Since it is the first boot priority, you may have to short one of the SPI data pins with ground in order for the SoC bootloader to skip SPI.

Are there any plans to implement or assist with the tow-boot launcher? It is attempting to provide a BIOS like experience for SBC at the moment.

Link to the Mezzanine tow-boot for example.

u-boot 2023.01 will have lots of bootmenu changes. We will reimplement the bootloaders on that version and add the proper menus then.
