https://devzone.nordicsemi.com/f/nordic-q-a/119384/eui64-value-on-nrf54l15Hi, It seems that CONFIG_IEEE802154_NRF5_UICR_EUI64_ENABLE is not supported on NRF54l15. Where should be the custom vendor EUI64 value stored? Only the FICR? Thanks in advance.

This result in that there is no place to store the <span>EUI64&nbsp;in the UICR. You would need to either use the default one in FICR or you store your custom address in the main flash.&nbsp;</span></p><div style="clear:both;"></div>
