PPK failing

Hi,

Thank you for clarifying.

You can erase the PPK with the command nrfjprog --eraseall in a terminal. The Power Profiler app will reprogram the PPK if it is not programmed with the correct firmware, so this should happen by itself when you open the device after erasing the PPK.

Best regards,

Marte

Sorry, while editing the post for an hour, I might have deleted the crucial parts :-)

When starting the Power Profiler App and selecting the DK in question, on the left side of the application, there is no start button, but the links to the help are still shown.

Could you provide me instructions, as to how to refresh the PPKs firmware?

Hi Torsten,

Can you clarify what the issue with the PPK is? You say that you are having problems getting it up and running. Is the issue with opening or starting the PPK, or does it fail when it is already running? Or is the problem something else?

Can you try erasing the firmware on the PPK and then programming it again?

Best regards,

Marte
