Applications for the mcb_rx14t board can be built, flashed, and debugged using standard
Zephyr workflows. Refer to Building an Application and Run an Application for more details.
Flashing
The program can be flashed to MCB-RX14T using the E2 Lite debugger by connecting the board’s 14-pin debug connector to the host PC. Here’s an example for building and flashing the Hello World application.
# From the root of the zephyr repository
west build -b mcb_rx14t samples/hello_world
west flash
Debugging
You can use Renesas Debug extension on Visual Studio Code for a visual debug interface. The configuration for launch.json is as below.
