https://devzone.nordicsemi.com/f/nordic-q-a/61306/flashing-custom-board-with-nrf52840-chipHello, I am using nRF52840, SDK_16.0.0, SoftDevice S140 V7.0.1 and Segger for flashing the image. I am using ‘ble_app_blinky’. 1) Previously we had a custom board with nRF52832. To flash that we are using another nRF52832 Development kit.

(Use the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fpin.html">pin assignments</a> for the nRF52840 to figure out what exact pin is SWDIO, SWDCLK, etc.)</p> <p>Programming should work from any nRF5x DK debug out port. Please note that the on-board SEGGER programmer on our DKs is licensed for development usage only, and not for production.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
