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

Hi again Paul

How exactly is the board powered through the DK? What pins on the DK are you using to power it? The debug pins are not sufficient, but since it's working using nRFConnect I assume you're good in that regard.

A few things you can check on your side: How does the folder where your .emProject file is located look. If you have more than the .emProject, .emSession and flash_placement.xml file there it might corrupt the SES project, so you can try to "clean the build folder" by deleting any excess files. Another thing is that you can check the path to the SoftDevice your application is using (if any).

Best regards,

Simon
