Programming and Debugging

The rsk_rx130 board supports the runners and associated west commands listed below.

flash debug

Applications for the rsk_rx130@512kb board target configuration can be built, flashed, and debugged as below.

Currently, the Zephyr SDK hasn’t added support for RX builds yet, so the GCC for RX toolchain is required and build system need to be set to use “cross-compile”.

export ZEPHYR_TOOLCHAIN_VARIANT=cross-compile
export CROSS_COMPILE=<Path to your toolchain>/bin/rx-elf-

  • Build the Blinky Sample for RSK-RX130-512KB:

cd ~/zephyrproject/zephyr
west build -p always -b rsk_rx130@512kb samples/basic/blinky

Flashing

Program can be flashed to RSKRX130-512KB via Jlink with RX adapter boards.

To flash the program to board

  1. Connect from board’s debug connector port to host PC using Jlink debugger.

  2. Execute west command

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.
