Building and Running a first example¶

This section details how to build and run the simple Blinky example.

Before you start building, remember to set up the nRF5 SDK development environment first:

Setup the nRF5 SDK

Building the example¶

Now it's ready to build the first example. Will use the Blinky example here to keep it simple.

The Blinky example shows how to blink the LEDs. The source code is located in nrf52840-m2-devkit/examples/nrf5-sdk/blinky.

Open terminal and navigate to the directory with the example Makefile:

cd ./nrf52840-m2-devkit/examples/nrf5-sdk/blinky/armgcc

Run make to build the example:

make

Running the example¶

After compiled, the firmware is located in blinky/armgcc/_build with the name nrf52840_xxaa.hex.

Connect the debugger USB port to your PC using the provided USB-C Cable. A disk drive called M2-DOCK will be automatically detected by the computer.

Run the following command in blinky/armgcc to program the board:

make flash_all

After programmed, the application will run automatically. Observe that the LEDs will start to blink as shown in this figure:
