Hello,

Hi

What debugger are you using, an nRF5 development kit or a J-Link debugger from SEGGER? How have you connected this debugger to your custom board? Please note that you also need to power the custom board when you want to flash an application onto it.

Best regards,

Simon

I'm using nrf52dk for flashing the code, the custom board is powered through the dk board, I'm able to flash hex file using nrf connect software but whenever i try flashing using segger I'm getting this error
