LABGRID-CLIENT(1) embedded testing LABGRID-CLIENT(1)

NAME

labgrid-client - labgrid-client interface to control boards

SYNOPSIS

labgrid-client --help

labgrid-client -p <place> <command>

labgrid-client places|resources

DESCRIPTION

Labgrid is a scalable infrastructure and test architecture for embedded (linux) systems.

This is the client to control a boards status and interface with it on remote machines.

OPTIONS

display command line help
specify the place to operate on
the crossbar url of the coordinator, defaults to ws://127.0.0.1:20408/ws
set the configuration file
set an initial state before executing a command, requires a configuration file and strategy
enable debugging
increase verbosity
proxy connections over ssh

CONFIGURATION FILE

The configuration file follows the description in labgrid-device-config(5).

ENVIRONMENT VARIABLES

Various labgrid-client commands use the following environment variable:

LG_PLACE

This variable can be used to specify a place without using the -p option, the -p option overrides it.

LG_TOKEN

This variable can be used to specify a reservation for the wait command and for the + place expansion.

LG_STATE

This variable can be used to specify a state which the device transitions into before executing a command. Requires a configuration file and a Strategy specified for the device.

LG_ENV

This variable can be used to specify the configuration file to use without using the --config option, the --config option overrides it.

LG_CROSSBAR

This variable can be used to set the default crossbar URL (instead of using the -x option).

LG_CROSSBAR_REALM

This variable can be used to set the default crossbar realm to use instead of realm1.

LG_PROXY

This variable can be used to specify a SSH proxy hostname which should be used to connect to the coordinator and any resources which are normally accessed directly.

LG_HOSTNAME

Override the hostname used when accessing a resource. Typically only useful for CI pipelines where the hostname may not be consistent between pipeline stages.

LG_USERNAME

Override the username used when accessing a resource. Typically only useful for CI pipelines where the username may not be consistent between pipeline stages.

MATCHES

Match patterns are used to assign a resource to a specific place. The format is: exporter/group/cls/name, exporter is the name of the exporting machine, group is a name defined within the exporter, cls is the class of the exported resource and name is its name. Wild cards in match patterns are explicitly allowed, * matches anything.

LABGRID-CLIENT COMMANDS

del-alias alias Delete an alias from a place

set-comment comment Update or set the place comment

set-tags comment Set place tags (key=value)

add-match match Add one (or multiple) match pattern(s) to a place, see MATCHES

del-match match Delete one (or multiple) match pattern(s) from a place, see MATCHES

add-named-match match name Add one match pattern with a name to a place

acquire (lock) Acquire a place

env Generate a labgrid environment file for a place

power (pw) action Change (or get) a place's power status, where action is one of get, on, off, status

io action Interact with GPIO (OneWire, relays, ...) devices, where action is one of high, low, get

console (con) Connect to the console

fastboot arg Run fastboot with argument

tmc command Control a USB TMC device

write-image Write images onto block devices (USBSDMux, USB Sticks, …)

reserve filter Create a reservation

cancel-reservation token Cancel a pending reservation

wait token Wait for a reservation to be allocated

reservations List current reservations

ADDING NAMED RESOURCES

If a target contains multiple Resources of the same type, named matches need to be used to address the individual resources. In addition to the match taken by add-match, add-named-match also takes a name for the resource. The other client commands support the name as an optional parameter and will inform the user that a name is required if multiple resources are found, but no name is given.

EXAMPLES

To retrieve a list of places run:

$ labgrid-client places


To access a place, it needs to be acquired first, this can be done by running the acquire command and passing the placename as a -p parameter:

$ labgrid-client -p <placename> acquire


Open a console to the acquired place:

$ labgrid-client -p <placename> console


Add all resources with the group "example-group" to the place example-place:

$ labgrid-client -p example-place add-match */example-group/*/*
