https://devzone.nordicsemi.com/f/nordic-q-a/122539/nrf5340-based-debuggerHello, I’m wondering if there is already a project or if one is planned to create a debugger based on the nRF5340. Currently, we use the DK to flash and debug custom PCBs based on nRF chips, but it’s not always ideal, especially when we need to flashen-USTelligent Community 13Thu, 26 Jun 2025 11:46:08 GMThttps://devzone.nordicsemi.com/thread/540578?ContentTypeID=1Thu, 26 Jun 2025 11:46:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:99a5c32c-c175-48cd-a017-23e08cfb62e6Roman Veselskyi<p><span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f62d.svg" title="Sob">&#x1f62d;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/540564?ContentTypeID=1Thu, 26 Jun 2025 09:46:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ecf590f4-83c4-4293-a196-961af7cc5281Turbo J<p>Have a look at OpenOCD.

So it&#39;s not possible that we can provide the nRF53 firmware for you to create your own debugger unfortunately.&nbsp;<br />But the idea of having a smaller debugger made by Nordic is good. I will forward it internally.&nbsp;</p> <p><br />What you can do is to think of using OpenOCD instead of Jlink.&nbsp;It&#39;s&nbsp;free to use but you need to dig into it and do some big banging I assume.&nbsp;</p><div style="clear:both;"></div>
