Depthcharge

The depthcharge boot method is used to boot a device using Depthcharge, the bootloader used by ChromeOS devices. LAVA waits for the Depthcharge command line interface, and then sends the configured boot commands.

- boot:
    method: depthcharge
    commands: nfs
    prompts:
    - 'root@debian:~#'
    timeout:
      minutes: 5

See Depthcharge for supported device configurations.

Note

A prior tftp deploy action is required.

commands

The boot method provides the following additional placeholders that can be used in the boot commands defined in the device type or job definition.

{DEPTHCHARGE_KERNEL}	TFTP path to the FIT image (if available) or kernel image
{CMDLINE}	TFTP path to the generated cmdline file
{DEPTHCHARGE_RAMDISK}	TFTP path to the ramdisk (empty when using a FIT image)

extra_kernel_args
