Bootloader¶

The bootloader boot method is used to power-on the DUT, interrupt the bootloader, and wait for the bootloader prompt.

- boot:
    method: bootloader
    bootloader: u-boot
    commands: []

bootloader¶

In order to interrupt the bootloader, the bootloader type should be specified in the bootloader parameter.

Note

The bootloader method type should match a boot method supported by the given device type. For example fastboot, minimal, pyocd, u-boot, etc.

commands¶

The commands parameter is required but can be kept empty. If some commands should be sent to the bootloader before the end of the action, provide them as a list in the commands parameter.

use_bootscript¶

When set to true, the boot commands are written to an iPXE script (script.ipxe) stored in the TFTP directory. The bootloader then executes a chainload command to run this script (e.g., dhcp net0; chain tftp://<worker_ip>/<path>/script.ipxe).

- boot:
    method: ipxe
    commands: ramdisk
    use_bootscript: true

Note

A prior tftp deploy action is required.

reset_connection¶

By default, LAVA will reset the previous connection when executing this action. You can skip this step by setting reset_connection: false.

- boot:
    method: bootloader
    bootloader: u-boot
    reset_connection: false

reset_device¶

By default, LAVA will reset the board power when executing this action. You can skip this step by setting reset_device: false.

- boot:
    method: bootloader
    bootloader: u-boot
    reset_device: false
