So far I have created a blinky application and run it successfully on the devkit for the nrf5340, even changeden-USTelligent Community 13Wed, 09 Mar 2022 02:42:18 GMThttps://devzone.nordicsemi.com/thread/357012?ContentTypeID=1Wed, 09 Mar 2022 02:42:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bdd6dc3e-1533-45b9-b87b-107818956c16Luis Alberto<p>Well... got a segger EDU mini with which we could program it, thanks!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/356986?ContentTypeID=1Tue, 08 Mar 2022 19:46:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8083508b-1206-4166-beba-e074356e40ffLuis Alberto<p>Hi Haakonsh,</p> <p></p> <p>I did try 3V on Vdd with the J-Link Lite, so now the J-link recognices the device, but...</p> <p></p> <p><img height="96" src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1646768601645v1.png" width="415" alt=" " /></p> <p>Do I need to upgrade J-Link software or does this means that it just cant program it?</p> <p>How can I use the 5340DK to program my unit?</p> <p>Thanks!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/356810?ContentTypeID=1Tue, 08 Mar 2022 09:53:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f1bc5a3b-13a7-4305-87ae-ff84d30e636ehaakonsh<p>I suggest you get your hands on an nRF5340DK. J-link Lite only supports 3.3V logic. If you are powering the nRF5340 through VDD at 3.3V you will have no issue, but if you&#39;re powering the nRF5340 through VDDH its default output will be 1.8V and you wont be able to use the J-Link Lite.&nbsp;<br /><br /><br /></p><div style="clear:both;"></div>
