https://devzone.nordicsemi.com/f/nordic-q-a/82616/jlink-could-not-connect-to-the-target-nrf51422qfabb0Hello! I have an self developed hardware which has an NRF51422QFAB (the shematic writes 51822, but it is pin compatible). I would like to program it, but I can not. :( This is my HW layout: I think this is not so complicated and good, too. en-USTelligent Community 13Mon, 13 Dec 2021 09:47:36 GMThttps://devzone.nordicsemi.com/thread/343095?ContentTypeID=1Mon, 13 Dec 2021 09:47:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:227e69da-37bf-447a-8b35-b93b37b7b496ktbalazs<p><span>I have to solder out the capacitor on the SWDIO and it worked.</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/342999?ContentTypeID=1Fri, 10 Dec 2021 22:49:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f2743e9c-390a-443d-83aa-5e41492d9c00ktbalazs<p>I tried it with another Jlink.</p> <p>Here is what I get.</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1639174689817v1.png" alt=" " /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/342922?ContentTypeID=1Fri, 10 Dec 2021 13:15:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0483fbe5-707d-46e6-9582-f20071673b69Vidar Berg<p>Hello,</p> <p>Please try to connect with Jlink commander (executable is named JLinkExe on Linux/macOS and jlink.exe on Windows), then post the result here.</p> <p>Example:</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1639142097266v1.png" alt=" " /></p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
