Barebox¶

The barebox boot method boots the downloaded files using barebox bootloader commands.

- boot:
    method: barebox
    commands: nfs
    auto_login:
      login_prompt: 'login:'
      username: root
    prompts:
    - 'root@debian:'
    timeout:
      minutes: 3

LAVA resets the device, interrupts barebox when the interrupt_prompt is printed, then sends the commands one by one, waiting for the bootloader_prompt after each command.

commands¶

Either the name of a set of commands defined in the device-type template, or a list of commands.

The base-barebox.jinja2 template defines:

Command	Description
`tftp`	Boot using `boot net`
`nfs`	Boot kernel and dtb via TFTP, mount the root filesystem via NFS
`ramdisk`	Boot kernel, ramdisk and dtb via TFTP

Custom commands

- boot:
    method: barebox
    commands:
    - bootm -v -o /mnt/tftp/{DTB} /mnt/tftp/{KERNEL}
    prompts:
    - 'root@debian:'

Placeholders like {KERNEL}, {DTB}, {RAMDISK}, {SERVER_IP} or {NFSROOTFS} are replaced by LAVA. See placeholder substitution.

auto_login¶

See auto_login.

prompts¶

See prompts.

transfer_overlay¶

See transfer_overlay.

Device configuration¶

The device-type template must extend base-barebox.jinja2. The following variables can be set in the device dictionary:

Variable	Default	Description
`bootloader_prompt`	`barebox`	Prompt printed by barebox
`interrupt_prompt`	`stop autoboot`	Message printed by barebox before booting
`load_addr`		Kernel load address used by `bootm`
`initrd_load_addr`		Ramdisk load address used by `bootm`
