Hi Piyush,

An easy way to get the log file is to explicitly set a path for it, say, as follows:

It would also be great if you could attach a photo of your connections.

Hi ,

Yes, power to the external board is separate and works at 5V, my custom board has power management IC which supplies 3v to the nrf52832 SOC, the VTG pin connected to the 5v of external board, and SWD interfaces as followed in above connections. The SWDIO and SWDCLK pin on external board SOC is pulled high to 3v with 10K resistor.

P19 is not connected to anything, all the SWD conenction are made from P20.

when I use nrfjprog --recover --log, I get the below error on console. I'm using nrf connet SDK for VScode, not Segger Embedded IDE. Could you tell where do I find the .log files in the system?

Hi Piyush,

Just to make sure, did you power the external custom board separately from the DK, such that voltage on the external board matches that of the DK?

Do you have P19 connected to anything?

When you use nrfjprog --recover --log, you are getting the error, but do you not get any logs?
