RIOT JLink helper

This tool was designed to simplify the handling of multiple, jlink-based development boards connected to your host machine when working with RIOT.

It simply maintains a mapping from user defined names to the tuple of (JLINK_SERIAL, BOARD, PORT) environment variables.

Usage

Short:

  1. run rjl-config.py [CONFIG_FILE]
  2. in your RIOT application, run e.g. rjl MY_TARGET_NAME make flash term

Long:

  1. Create a configuration file with all your nodes, their jlink serial numbers, and custom names. The default location for this file is ~/.rjl.yml. See also the config_example.yml file in this repository.

  2. Run jrl-config.py from anywhere on your system. This will iterate through all /dev/ttyACM* devices currently connected to the host system. All devices that have an entry in the selected configuration file will be put into a temporary mapping file.

  3. Go into any RIOT application folder and simply call rjl.py NAME make term or whatever RIOT make command you need. The NAME parameter will take care of automatically setting the the BOARD, JLINK_SERIAL, and PORT environment variables to the configuration tied to that target name.
