Applications for the rsk_rx130@512kb board target can be built, flashed, and
debugged in the usual way. See Building an Application and
Run an Application for more details on building and running.
If you want to build Zephyr application for RSK-RX130 board using Renesas GCC RX toolchain follow the steps below:
Download and install GCC for RX toolchain:
Set env variable:
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 using Jlink with RX adapter boards, by connecting the board’s debug connector port 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 rsk_rx130@512kb 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.
