If it was ESD related, then it must have been caused by touching the DK, as the board only exposes the JTAG connector; which is very hard to touch unless it was done on purpose. However, all hardware related issues are on the table and have not been ruled out at all. The only reason that places these issues on the very unlikely side, is that we have more than 30 boards with the same hardware 12 of which have been under software development for at least 2 months now. The only board that encountered this issue, has been erased many times using the erase board in VScode.&nbsp;</p> <p>Kindest regards,</p> <p>Yasir</p><div style="clear:both;"></div>RE: Serial Wire Debug Clock (SWDCLK) stuck at 2V!https://devzone.nordicsemi.com/thread/353781?ContentTypeID=1Fri, 18 Feb 2022 08:56:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6b02a31a-5f79-453c-bc79-da060708d2e3&#216;yvind<p>Are you able to provide schematics and pictures of your setup?

Are there any configurations done to the DK? Solder bridges cut or soldered?[/quote] <p>Basically, the nrf5340 SoC on our custom board had a problem with the SWDCLK pin, by measuring resistance on that pin to GND (on the custom board), it was at around 270 ohms without connecting it to the DK. For a working device the SWDCLK pin is at around 12 mega ohms. So with one of our working custom boards the voltage at that pin with the DK connected is 3.3V but for that board (with the initial problem) before changing the SoC it was 2V as shown before (with it connected to the DK). By disconnecting the JTAG cable from our device the DK works just fine (nrfjprog --deviceversion ...etc.), we also tried with several DKs. Again the problem was solved by changing the SoC on our custom board. Since the board was not responding to any command from the DK, and because the SWDCLK goes directly from the JTAG connector to the SWDCLK pin on the SoC on our board, the only option for us was to change it. The nrf5340 SoCs we have are the D revision ones.</p> <p>Our custom board is enclosed in a cover with only the JTAG exposed for programing and debugging. It is power by a rechargeable battery.</p> [quote userid="77062" url="~/f/nordic-q-a/84711/serial-wire-debug-clock-swdclk-stuck-at-2v/353260#353260"]Are you measuring correct voltage on SWDCLK now?&nbsp;[/quote] <p>Yes with the DK connected its now at 3.3V before it was 2V.</p> <p><span>The problem occurred after using the erase board in the nrf connect extension for Vscode.</span></p> <p>Sincerely,</p> <p><span>Yasir</span></p> <p><span>&nbsp;&nbsp;&nbsp;</span></p><div style="clear:both;"></div>RE: Serial Wire Debug Clock (SWDCLK) stuck at 2V!https://devzone.nordicsemi.com/thread/353260?ContentTypeID=1Wed, 16 Feb 2022 08:12:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b3c85fc-fb40-47c9-a951-588a33e2611b&#216;yvind<p>Hi Yasir,</p> <p>The SWDCLK should be provided by the DK, have you measured directly on the DK?
