The reason for using ZMS on the nRF54 Series Seises is that it is optimized for the RRAM memory technology used in these devices.</p> <p>For more information, see <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf54l/zms.html">nRF54L Device Guide</a> and <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_guide_2.8.html#nrf54l_series">Migration Guide 2.8</a>.</p> <p>Best regards,<br />Marte</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/529034?ContentTypeID=1Wed, 26 Mar 2025 11:45:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f480a78-826b-400b-a71f-a4e9a33d1152md9981<p>I found the issue. The CONFIG_NVS was set to n in another board.conf file. The reason being a workaround required as Zephyr L2 implies usage of NVS backend for settings.<br />How can I still use NVS for user specific data storage? Is a separate instance or partition required?</p><div style="clear:both;"></div>
