LABGRID-DEVICE-CONFIG(5)

NAME
labgrid-device-config - labgrid test configuration files

SYNOPSIS

*.yaml

DESCRIPTION

To integrate a device into a labgrid test, labgrid needs to have a description of the device and how to access it.

This manual page is divided into section, each describing one top-level yaml key.

TARGETS

The targets: top key configures a target, it's drivers and resources.

The top level key is the name of the target, it needs both a resources and drivers subkey. The order of instantiated resources and drivers is important, since they are parsed as an ordered dictionary and may depend on a previous driver.

For a list of available resources and drivers refer to https://labgrid.readthedocs.io/en/latest/configuration.html.

OPTIONS

The options: top key configures various options such as the crossbar_url.

  OPTIONS KEYS

crossbar_url
    takes as parameter the URL of the crossbar (coordinator) to connect to. Defaults to 'ws://127.0.0.1:20408'.

crossbar_realm
    takes as parameter the realm of the crossbar (coordinator) to connect to. Defaults to 'realm1'.

IMAGES

The images: top key provides paths to access preconfigured images to flash onto the board. The image paths can be either relative to the YAML file or absolute.

  IMAGE KEYS

The subkeys consist of image names as keys and their paths as values. The corresponding name can than be used with the appropriate tool found under TOOLS.

  IMAGE EXAMPLE

Two configured images, one for the root filesystem, one for the bootloader:

images:
  root: "platform-v7a/images/root.img"
  boot: "platform-v7a/images/barebox.img"

TOOLS

The tools: top key provides paths to binaries such as fastboot.

  TOOLS KEYS

fastboot
    Path to the fastboot binary

mxs-usb-loader
    Path to the mxs-usb-loader binary

imx-usb-loader
    Path to the imx-usb-loader binary

  TOOLS EXAMPLE

Configure the tool path for imx-usb-loader:

tools:
  imx-usb-loader: "/opt/labgrid-helper/imx-usb-loader"

IMPORTS

The imports key is a list of files or python modules which are imported by the environment after loading the configuration. Paths relative to the configuration file are also supported. This is useful to load drivers and strategy which are contained in your testsuite, since the import is done before instantiating the targets.

  IMPORTS EXAMPLE

Import a local myfunctions.py file:

imports:
  - myfunctions.py

EXAMPLES

A sample configuration with one main target, accessible via SerialPort /dev/ttyUSB0, allowing usage of the ShellDriver:

targets:
  main:
    resources:
      RawSerialPort:
        port: "/dev/ttyUSB0"
    drivers:
      SerialDriver: {}
      ShellDriver:
        prompt: 'root@\w+:[^ ]+ '
        login_prompt: ' login: '
        username: 'root'

A sample configuration with RemotePlace, using the tools configuration and importing the local mystrategy.py file. The MyStrategy strategy is contained in the loaded local python file:

targets:
  main:
    resources:
      RemotePlace:
        name: test-place
    drivers:
      SerialDriver: {}
      ShellDriver:
        prompt: 'root@\w+:[^ ]+ '
        login_prompt: ' login: '
        username: 'root'
      MyStrategy: {}
      IMXUSBLoader: {}
tools:
  imx-usb-loader: "/opt/lg-tools/imx-usb-loader"
imports:
  - mystrategy.py
