nRF Connect Error programming Power Profiler

[Mik]

Hi,

i would like to use the Power Profiler v2.0.0 from nRF Connect Software. The Power profiler is connected and it works with the Software 1.0.0. When i launch the power profiler app and select the serial port, which shows the right com port with the NRF52DK ID, a window pops up to program the required firmware

after confirming with yes, i alwas get the error message below:

I've just installed the latest nRF Command line tools and the problem still occurs.

What else can i do to get it work?

Kind regards

Michael

Can you try to erase the chip manuaaly before starting the power profiler.  Seems like it is not able to program the chip for some reason? Memory protected or something

I've erased the PPK by using the comand: "nrfjprog --family nrf52 --eraseall" and did a power on reset. The problem still occurs - no change in behavior. There is no Memory protection on the DK programming with other exampes works fine (e.g. blinky).

Can you please tell me which OS and version you are running this on? also the exact version of nRF52DK, I can ask some help from our app developer to look at this one, once you gave me your environment details.

I had the same issue after accidentally flashing our own memory protected firmware onto the device.
A "nrfjprog --family nrf52 --recover" fixed it for me.

As a note:
I did have to connect the board stack with com set to ext, then switching it to DK with the board stack still connected over USB.
If I didn't do this nrfjprog claimed "ERROR: There is no debugger connected to the PC."
