Programming external board with nRF52 DK

[Marshed]

Hi, 

I am trying to program nRF52832 custom circuit with nRF52 DK, I have connected debug out from the nRF52 DK to the custom circuit containing nRF52832 debug in. When I try to load the program to the custom board using SEGGER Embedded Studio I get the following error.  Can anyone tell me how to fix this problem?

Hi, 

Have you tried recovering the board using 'nrfjprog --recover' command? 

Please upload the log that is generated, when you run

nrfjprog --recover

You need to install the nRF-Command-Line-Tools, and either add the directory to your PATH, or run the command from a command line inside the directory.

The DK should be connected to the chip that you want to recover. If this is on the custom PCB, you will have to connect it to this.
