https://devzone.nordicsemi.com/f/nordic-q-a/92992/vscode-jlink-programming-hang-on-new-boardHi, I am using NCS v2 with VSCode on Windows 11. I am using the jlink programmer inside a nRF52840-DK to program a custom board. Actually, two different custom boards. My question is about a seeming change in behavior of jlink between the two customen-USTelligent Community 13Wed, 19 Oct 2022 16:00:07 GMThttps://devzone.nordicsemi.com/thread/391506?ContentTypeID=1Wed, 19 Oct 2022 16:00:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2334bb4d-61a0-4f06-88a0-8f4b8c39cca9tesc<p>Hi,</p> <p>What you describe are symptoms that may be seen if DC/DC is enabled without the proper inductor on the board. The module most likely has the components in place for using DCDC, and CONFIG_BOARD_ENABLE_DCDC is on by default in the SDK. See <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fref_circuitry.html&amp;anchor=unique_609532902">the reference circuitry for the nRF52840 QIAA</a> for the reference circuitry, and in particular inductor L4 and related circuitry. Either you need this circuitry on the board (for using DCDC) or you must disable DCDC for the project through the aforementioned setting.</p> <p>Regarding the jlink runner, thanks for the suggestion! I will forward your observations to the extension development team.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
