How to enter flash mode

Direct flashing over EDL is possible, but not very user friendly. It is recommended to plug the storage device into a PC or laptop and install with pmbootstrap install --disk=/dev/sda or similar and then simply power on the board with the storage attached.

Installing

  • Run pmbootstrap init and select vendor qcom, codename qcs6490.
  • Run pmbootstrap install --disk=… (pointing to e.g. the SD card)

Update SPI Boot Firmware

If postmarketOS fails to boot, you need to update the SPI Boot Firmware.
