We faced the issue that some of our NRF52832 Raytac modules (MDBT42Q-512KV2) don't respond over the SWD interface. But all of these modules were working previously and we were able to flash them.
Is there a possibility to check the SWDIO / SWDCLK pins? E.g. measure the pull-up / pull-down resistance to check if there is an ESD problem?
