jlink_dock

jlink_dock

This is a framework for serving connected JLink board as service. (Currently only designed for Linux platform)

When a USB device is plugged in, jlink_dock automatically starts a Docker container and initiates a service inside the container. This service enables the user to flash the connected JLink board by uploading an ELF file and a script to a REST API. jlink_dock then flashes the board with the ELF file and runs the uploaded script after flashing.

Usage:

To use this tool there are some preparation needed:

1. Run udevadm monitor -p on host, and connect jlink board to it, and note down the ID_SERIAL_SHORT and the type of the board.

2. Create a sqlite database using the following command, then update /path/to/jlink\_dock.sh:6 for correct path to database:

   sqlite3 /path/to/board.db  "create table stm32(serial NCHAR(12) primary key, type NCHAR(11));"
   

3. Insert the SERIAL and Type mapping to the database created in prior step.

4. Put 51-jlink_dock.rules into /etc/udev/rules.d, and update /path/to/jlink_dock.sh to the correct value.

5. Make the udev rules to take effort, for example using the following command.

   udevadm control --reload   # Reload udev rules
   udevadm trigger            # Re-trigger the udev events

Now for each of jlink board connected to the host, there will be a container started to it.
