Here are some few steps you can try out (in no particular order):&nbsp;</p> <ul> <li>Verify that your J-Link version is compatible with the your SDK and nrfutil versions. If you have newer version than <em></em>the tested version<em>&nbsp;</em>it<em>&nbsp;may</em>&nbsp;work, but we have no guarantee. If you have an older version, please upgrade. For the newest nrfutil version v8.66 is tested.&nbsp;</li> <li>Restarting VS Code and plugging in the DKs again sometimes fixes these kinds of errors.</li> <li>Rebooting the computer sometimes fixes these kinds of errors.</li> </ul> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>
