(check you prj.conf file and overlay file).&nbsp;</p> <p>Also, I noticed that in your code snippet, it says &quot;m_spi_master_0&quot;, but I don&#39;t see where that instance is set, so it could be just the name. But is it really using SPI instance 1 or 0?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
