Thank you I will try that. But on the other hand: having a dedicated reset button that actually resets the MCU would be a cool feature ;-)

You could try calling nrfjprog --reset

Ok, but how should this help to generate a reset? Lets assume, my firmware is running in an endless loop, even if I have defined DEBUG somewhere, what will generate a reset inside the microcontroller. If it's the Jlink MCU, that is supposed to generate some kind of reset via JTAG, when I press the reset button, I wonder, how this is influenced by setting any preprocessor symbol in the targets firmware?

I just flash the firmware using JLink. Maybe I have to configure the interface MCU somehow to generate the debugger reset, when the reset button is pressed?

Hi,

I mean defined DEBUG like shown in this question.

Hi Øyvind, thank you for your answer! What Do you mean by "defined DEBUG"? Do you mean, that the software I write have to implement some kind of support for this?

Hi,

The reset on the DK is wired through the interface MCU, when pressing the reset button the interface MCU should perform a debugger reset. If you have defined DEBUG mode then the debugger reset might not propagate.

Best regards,
