https://devzone.nordicsemi.com/f/nordic-q-a/4138/j-link-eduHi, Can I use the J-Link Edu programmer to flash the nrf51822? Right now I&#39;m using the J-Link LITE CortexM that I get from the development kit to flash the firmware into mu custom nrf51822 pcb but I need another programmer and I have access to a J-Linken-USTelligent Community 13Sat, 18 Oct 2014 00:17:37 GMThttps://devzone.nordicsemi.com/thread/14802?ContentTypeID=1Sat, 18 Oct 2014 00:17:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cbe04b36-0d61-484d-bdef-918454ff34b6Jose Xavier<p>Thank you both :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14801?ContentTypeID=1Fri, 17 Oct 2014 13:36:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8c777847-c84f-4c16-9c43-b6a9701780a5Vebj&#248;rn<p>I have used the J-Link EDU to program the beacon (nRF51822) so that is confirmed to work :) Keep in mind the nRF doesnt support JTAG, though, so you need to use the SWD signals. These signals have the same name as on the nRF51822 chip, but in the pinout TMS corresponds to SWDIO, and TCK to SWCLK so that looks correct!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14800?ContentTypeID=1Fri, 17 Oct 2014 13:35:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f2ff10d3-601d-44cf-a64f-3375e48d0a81testy<p>j-link <strong>EDU</strong> communicates with nRF51 successfully, even with <strong>lower Vcc</strong> benefit.</p> <p>Described wiring is OK, no need to connect RESET (15) of the standard 20-pin connector.</p><div style="clear:both;"></div>
