Hello ,
I am trying to program external custom board through another nrf52dk via SWD interface to check if external programming method works. The connections between two devices are below.
when using nrf connect SDK for VS code(Zephyr) the error screenshot is below. I checked the custom board is powered on at 5v operating voltage but failed to detect through main nrf52dk. I checked the voltages on SWDIO is around 3v and SWDCLK is at 0v pulled down internally based on the data sheet.
I get this error when recovering the device using nrfjprog --recover --log. Aditionally, please guide where to find the .log file in nrf connect for vs code IDE.
