DFU

The dfu boot method flashes and boots devices using the USB DFU (Device Firmware Upgrade) protocol.

- boot:
    method: dfu
    timeout:
      minutes: 10

Note

Images should be deployed using the tmpfs deploy action before using this boot method. Each image entry in the deploy action should include an image_arg containing the DFU --alt and --download arguments.

Installation

The boot method invokes dfu-util on the worker to download images to the device over USB. The utility must be installed on the LAVA worker.

sudo apt-get install dfu-util

Configuration

To add a new device, see DFU.
