Recover on-board flash

  • Connect to the serial console
  • Install the SPI.1A module on the SPI header of the apu2 system board. Please watch the orientation (white stripe).

  • Then power on.
  • The SPI module will override the on-board flash, which could be blank or corrupted.
  • Boot tinyCore Linux from a USB stick.
  • Then remove the SPI module while power is on
  • Reboot
