If you&#39;re going to develop using Nordic products, I would recommend you to use NCS (which includes a downstream version of Zephyr). Follow the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_assistant.html#getting-started-assistant">Getting Started Assistant</a> strictly and you should be able to build using west.</p> <p>If you intend to use upstream Zephyr, you may get some help in any of these Zephyr resources:&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_assistant.html#getting-started-assistant">https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_assistant.html#getting-started-assistant</a>.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
