As that board has an SD card connector populated, I was able to use an VFAT SD card for storing Python programs. For the FRDM-MCXN947 the situation is different. Although the MCXN947 micro-controller features an SD controller, the Freedom board is lacking the actual SD card connector as it is not populated, probably to save money. As I am a software guy, mounting this SMD connector is more difficult than looking for software alternatives, so let's find out if we can use the internal flash or the external QSPI as a file system instead. </p> <div style="text-align:center" class="imageblock" id="org8261cce"> <div id="org222e5b2" class="figure"> <p><img src="https://blog.lazy-evaluation.net/de/images/micropython-logo.jpeg" alt="micropython-logo.jpeg" title="Big lock" align="middle" width="150"> </p> </div> </div> <p><a href="https://blog.lazy-evaluation.net/de/posts/embedded/micropython-zephyr-mcxn947.html?pk_campaign=feed">Weiterlesen…</a> (7 min verbleiben zum Lesen)</p></div>https://blog.lazy-evaluation.net/de/posts/embedded/micropython-zephyr-mcxn947.htmlThu, 13 Feb 2025 21:24:15 GMThttps://blog.lazy-evaluation.net/de/posts/embedded/micropython-zephyr-imxrt1060.html?pk_campaign=feedDetlev Zundel<div><p> Not having looked at the <a href="https://docs.micropython.org/en/latest/zephyr/tutorial/intro.html">MicroPython "port" for the Zephyr operating system</a>, I decided to check the current state of it.
