In this section we will explain the steps on how to setup the board in the Fastboot Mode. Fastbood Mode is used for recovering/flashing the board over USB, however, if the device fails to boot up after image flashing with Fastboot, try to flash the FlatBuild image.

Note

Please read every step before starting.

To enter Fastboot mode, follow the next steps related to the hardware pieces highlighted in Figure 1.

Via Buttons Combination

1. Power off the device.

2. Make sure there's no USB-C cable connected to the board.

3. Hold the Volume Down button and press the Power On button, then release the Volume Down button about 5 seconds later.

4. Plug a USB-C cable between your PC and the USB Type C port of the board.

Check that the device entered in Fastboot mode by running:
