programming nRF5340 with nrfjproghttps://devzone.nordicsemi.com/f/nordic-q-a/110229/programming-nrf5340-with-nrfjprogI&#39;ve been working for a year now programming nRF5340 DKs using nrfjprog and I still can&#39;t seem to figure out what is the right way to program them. It is also very random. I tend to get error 90: ``` - Encountered error -90: Command read_device_infoen-USTelligent Community 13Mon, 24 Jun 2024 17:08:47 GMTRE: programming nRF5340 with nrfjproghttps://devzone.nordicsemi.com/thread/490413?ContentTypeID=1Mon, 24 Jun 2024 17:08:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ffe8c45e-3d50-4531-850c-d62c2110c429Nguyen Hoan Hoang<div class="content full threaded-reply-content user-defined-markup" data-replyid="490412" data-userid="3482" data-permalink="~/f/nordic-q-a/99326/nrf5340-production-programming-dfu/490412"> <div class="content"> <p>Low cost production programming of the nRF5340 is now available. &nbsp;It can parallel flash multiple boards at once.&nbsp;</p> <p>It is available at mouser&nbsp;<a href="https://www.mouser.com/ProductDetail/I-SYST/CS-BLYST-08?qs=T3oQrply3y%252BhSfpc3hK%2FLg%3D%3D">https://www.mouser.com/ProductDetail/I-SYST/CS-BLYST-08?qs=T3oQrply3y%252BhSfpc3hK%2FLg%3D%3D</a></p> <p>Parallel flashing software download here&nbsp;<a href="https://sourceforge.net/projects/idaplinkfirmware/files/">https://sourceforge.net/projects/idaplinkfirmware/files/</a></p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/Screenshot-2024_2D00_06_2D00_24-at-1.03.15_2F20_PM.png" /></p> <div></div> </div> </div> <div class="edit-form"></div> <div class="actions meta default"></div><div style="clear:both;"></div>RE: programming nRF5340 with nrfjproghttps://devzone.nordicsemi.com/thread/478785?ContentTypeID=1Mon, 15 Apr 2024 13:08:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d99a684c-b980-4046-baaa-b945cf24ecb0Einar Thorsrud<p>Hi,</p> <p>If you have updated nRF Command line tools, you should normally be able to recover from most states by first recovering the network core, then the application core. Like this:</p> <p><code>nrfjprog --recover --coprocessor CP_NETWORK &amp;&amp; nrfjprog --recover</code></p><div style="clear:both;"></div>
