Programming and debugging
Building & Flashing
You can build and flash an application in the usual way (See Building an Application and Run an Application for more details).
Here is an example for building and flashing the Blinky application.
# From the root of the zephyr repository
west build -b mikroe_clicker_ra4m1 samples/basic/blinky
west flash
Debugging
Debugging also can be done in the usual way. The following command is debugging the Blinky application. Also, see the instructions specific to the debug server that you use.
# From the root of the zephyr repository
west build -b mikroe_clicker_ra4m1 samples/basic/blinky
west debug
