Firmware update

The following documentation describes the process of Dasharo open-source firmware update. If your device is currently flashed with the original PC Engines firmware firmware please refer to the Initial deployment documentation.

The update process may be different, depending on the currently installed Dasharo firmware version.

We recommend Dasharo Tools Suite, but if you really want to do this manually please follow guide below.

Before updating, ensure the SPI flash WP pin is not active - BIOS write protect pin jumper on J2 (apu2) or J3 (apu3/4/6).

Additionally, before starting the update procedure be sure to disable Secure Boot:

  1. Power on the device.
  2. While the device is booting, hold the DELETE key to enter the UEFI Setup Menu.
  3. Enter the Device Manager menu.
  4. Enter the Secure Boot Configuration submenu.
  5. Verify that the Current Secure Boot State field says Disabled - if not, unselect the Attempt Secure Boot option below then press F10 to save the changes.
  6. Reboot the device to properly apply the changes.

The settings of all the above options can be restored after a firmware update.
