Programming and Debugging

The holyiot_25008 board supports the runners and associated west commands listed below.

	flash	debug	rtt	attach	debugserver
jlink	✅	✅ (default)	✅	✅	✅
nrfutil	✅ (default)

The board must be programmed using an external SWD probe connected to SWDIO, SWCLK, VDD, and GND.

Flashing

Here is an example for the Blinky application:

# From the root of the zephyr repository
west build -b holyiot_25008/nrf54l15/cpuapp samples/basic/blinky
west flash
