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="orga310132"> <div id="org50ee260" class="figure"> <p><img src="https://blog.lazy-evaluation.net/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/posts/embedded/micropython-zephyr-mcxn947.html?pk_campaign=feed">Read more…</a> (7 min remaining to read)</p></div>imxrtmcxnmicropythonnxppythonzephyrhttps://blog.lazy-evaluation.net/posts/embedded/micropython-zephyr-mcxn947.htmlThu, 13 Feb 2025 21:24:15 GMThttps://blog.lazy-evaluation.net/posts/embedded/nxp-mcxn-zephyr.html?pk_campaign=feedDetlev Zundel<div><p> First announced in <a href="https://www.nxp.com/company/about-nxp/nxps-new-mcx-n-microcontrollers-usher-in-new-era-of-smart-efficient-edge-processing:NW-NXP-NEW-MCX-N-MICROCONTROLLERS-USHER-IN-NEW">2022</a>, I finally have an MCX-N evalboard fron <a href="https://www.nxp.com/">NXP</a> on my table. The <a href="https://www.nxp.com/design/design-center/development-boards-and-designs/general-purpose-mcus/frdm-development-board-for-mcx-n94-n54-mcus:FRDM-MCXN947">FRDM-MCXN947</a> eval board has a nice form factor and so I am eager to see if I can Zephyr to run on that board. The <a href="https://docs.zephyrproject.org/latest/boards/nxp/frdm_mcxn947/doc/index.html">Zephyr documentation</a> for the eval board seems to indicate that this should be easy to do. Let's find out. </p> <div style="text-align:center" class="imageblock" id="org446bcf8"> <div id="org6bf9a3e" class="figure"> <p><img src="https://blog.lazy-evaluation.net/images/FRDM-MCXN947-TOP.png" alt="FRDM-MCXN947-TOP.png" title="Photo of FRDM-MCXN947" align="middle" width="400"> </p> </div> </div> <p><a href="https://blog.lazy-evaluation.net/posts/embedded/nxp-mcxn-zephyr.html?pk_campaign=feed">Read more…</a> (11 min remaining to read)</p></div>linkservermcuxpressoidemcxmcxnnxpzephyrhttps://blog.lazy-evaluation.net/posts/embedded/nxp-mcxn-zephyr.htmlMon, 29 Apr 2024 15:05:41 GMT
