Zephyr RTOS explorations and building blocks

^ USART references

"Hello world" example build command: 

 west build -b circuitdojo_feather_nrf9160ns samples/hello_world -p

Programming command: 

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


^ LIS2DH example project build errors

Build errors when attempting to compile LIS2DH sensor example with circuitdojo board as target board:

^ Setting Up Revisit

This link from Zephyr's documentation home page / home site a good and detailed overview of the Zephyr RTOS project:

Detailed steps to install Zephyr's needed build tools and Zephyr SDK:

Board support for CircuitDojo nRF9160 Thing Plus is not available in either Nordic's ncs v1.4.1 SDK nor Zephyr's SDK which comes as part of Zephyr 2.6.0. Steps to locating an SDK which include board support and files for the Thing Plus include navigating the following URLs:

Link (3) Jared Wolff does not spell out nor provide a direct link to an SDK supporting the nRF9160 Thing Plus.
