https://devzone.nordicsemi.com/f/nordic-q-a/127483/fota-on-nrf54lm20a-dk-using-external-flash-sqspiHello, I am currently trying to make an application that can do FOTA and store the secondary firmware image on an external flash using sQSPI. The project I started is based on the smp_svr sample using v3.2.3 of the SDK and v0.3.4 of the nRF54LM20A.en-USTelligent Community 13Wed, 18 Mar 2026 15:31:16 GMThttps://devzone.nordicsemi.com/thread/563602?ContentTypeID=1Wed, 18 Mar 2026 15:31:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e014658b-2626-4d9b-9c1c-6417d63b409fduncmac<p>We currently don&#39;t have a v0.5.1, but we&#39;re interested in moving to using the engineering B SoC version of the LM20A. We will try again once we have a newer version of the board.</p> <p>Thanks for the info!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/563575?ContentTypeID=1Wed, 18 Mar 2026 13:30:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b85764c0-df25-4ae9-9d4b-964211bdb3e3AHaug<p>Hello,</p> <p>I believe the troubles you&#39;re seeing has to do with the version of the&nbsp;<span>nRF54LM20A that you&#39;re using. See&nbsp;</span>&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/127479/nrf54lm20-sqspi-lock-ups">nRF54LM20 sQSPI lock ups</a>&nbsp;&nbsp;for more details.</p> <p>Do you have a v0.5.1 version of the DK to verify this against? From what I can see, sqspi + external flash should work for the v0.5.1 version, but the behavior is unreliable/not workign for v0.3.4</p> <p>Kind regards,<br />Andreas</p><div style="clear:both;"></div>
