In order to use SEGGER and OpenOCD debug probes within the container, some udev rules need to be installed on the host machine. A setup script has been provided to aid with installation.
-
Run
setup-devcontainerinside the container -
Close the container, and re-open the work directory on your host
-
Run the
install-rulesscript inside.vscode/setup/on your host machinecd .vscode/setup sudo ./install-rules
To access a serial port inside the devcontainer, use the cu command as shown below:
cu -l <serial port device> -s <baudrate>
e.g. "cu -l /dev/ttyACM0 -s 115200".
To close the connection, press RETURN/ESC/Ctrl-C, type "~." (tilde, dot) and wait for 3 seconds.
