Blinky Sample

Change directories to ncs/zephyr/samples/basic/blinky. Then compile as shown before in the compiling section of this guide.

Before you do compile make sure that the following lines are added to the prj.conf:

# Enable Zephyr application to be booted by MCUboot

This will enable support for the bootloader. Then, build using the build command:

west build -b circuitdojo_feather_nrf9160ns

You can see towards the end of this output that both the application and the bootloader have been built and merged.

Programming can be completed with newtmgr:

newtmgr -c serial image upload build/zephyr/app_update.bin
newtmgr -c serial reset

Note: pre-built binary can be downloaded here: blinky-v1.3.2.bin
