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.
yaml
- 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¶
See 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.
| Placeholder | Description |
|---|---|
{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¶
Extra kernel command line arguments to append to the kernel cmdline defined
in the device type.
yaml
- boot:
method: depthcharge
commands: nfs
extra_kernel_args: "debug loglevel=7"
