Programming and Debugging

Applications for the blueclover_plt_demo_v2_nrf52832 board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing

Flashing Zephyr onto the blueclover_plt_demo_v2_nrf52832 board requires an external programmer. The programmer is attached to the SWD header.

Build the Zephyr kernel and the APA102 Sample Application sample application.

west build -b blueclover_plt_demo_v2_nrf52832 samples/drivers/led_apa102

Flash the image.
