If you don&#39;t define that using --debug-mode wouldn&#39;t work.&nbsp;</p> <p>From what I can see in the code when you use&nbsp;<span>NRF_DFU_DEBUG,&nbsp;fw_version_ok() will be skipped and it&#39;s where the bootloader version is checked.&nbsp;</span></p> <p>&nbsp;<img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1668778042865v2.png" alt=" " /></p> <p></p> <p>If you already define&nbsp;<span>NRF_DFU_DEBUG, you may want to debug and check what caused the invalid parameter in the bootloader.&nbsp;</span></p><div style="clear:both;"></div>
