https://devzone.nordicsemi.com/f/nordic-q-a/81208/zephyr-master-branch-check-outHi, I noticed that in the main / master repository of Zephyr there are features that are not yet available to the version coming with NCS (for example the State Machine Engine in zephyr / lib /smf/ ). Is there a way the master branch can be retrieveden-USTelligent Community 13Fri, 29 Oct 2021 12:38:42 GMThttps://devzone.nordicsemi.com/thread/336681?ContentTypeID=1Fri, 29 Oct 2021 12:38:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d0c8dc38-f393-4e8a-8015-9451fbf2b8e8&#216;ivind<p>Hi,</p> <p>I would not recommend adding the zephyrproject-rtos/zephyr main branch to the nRF Connect SDK. This&nbsp;will&nbsp;cause a lot of issues. You can instead try to port the libraries you want to the version used in the SDK.<br />zephyr/lib/smf seems to just be a handful of files, so it may not be too difficult to add. If you have difficulties porting it to 1.7.0/1.7.1, you can try to use the main branches of nrfconnect/sdk-nrf and nrfconnect/sdk-zephyr.</p> <p>But, if you are willing to deal with any incompatibilities or other issues, you should be able to make &#39;west update&#39; retrieve the zephyrproject-rtos/zephyr main branch by editing the nrf/west.yml file.</p><div style="clear:both;"></div>
