If not, did you specify in the board files/overlay files that it doesn&#39;t have that?</p> <p></p> <p>Regarding the lack of nRF54L05 from the list in J-Link Commander, you need to update the version of J-Link. Try installing J-Link v8.58, I see that the nRF54L10 and nRF54L05 are selectable in that version.</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
