Boot Management

LAVA offers many facilities to control the boot process of a DUT. This enables users to configure the boot process to support custom software images.

Boot Commands Stanzas

Boot command stanzas are predefined Boot Commands which are included in the device_configuration or in the device_type_configuration.

Boot Commands

The following example demonstrates how to define a boot command stanza.

Example:

boot_cmds =
    setenv initrd_high "'0xffffffff'",
    setenv fdt_high "'0xffffffff'",
    setenv bootcmd "'fatload mmc 0:3 0x80200000 uImage; fatload mmc 0:3 0x81600000 uInitrd; fatload mmc 0:3 0x815f0000 board.dtb; bootm 0x80200000 0x81600000 0x815f0000'",
    setenv bootargs "'console=ttyO0,115200n8 root=LABEL=testrootfs rootwait ro'",
    boot

In the above example “boot_cmds” is the name of the stanza.

Boot Options

Boot options are predefined Boot Commands which are included in the device_configuration or in the device_type_configuration.

Configuration

The following example demonstrates how to enable, define, and set the default boot_options in either the device_configuration or in the device_type_configuration.

Example:

boot_options =
    boot_cmds

[boot_cmds]
default = boot_cmds

The “boot_cmds” stanza defines
