PPK: Unable to connect to the ppk, check debugger connection and make sure pynrfjprog is up to date

I'm trying to use the PPK with an nRF51 dev board, and I'm getting this output whenever I try to start the PPK Software:

Unable to connect to the PPK, check debugger connection and make sure pynrfjprog is up to date.

As far as I can tell, I have the PPK connected correctly. The PPK is on the NRF51 dev board, USB is connected to the NRF51 dev board, Power Select on the PPK is set to "DK", but the application won't start.

All switches are in 'DK' position as described here?

You are sure the PPK is correctly mounted on the DK (all pins align)?

You can check if you have connection to the PPK chip through the debugger by for example running the command nrfjprog -r -f nrf52. Make sure that SB9 is cut on the DK so that the chip you 'see' is not the one on the DK.

If the wrong firmware is running on the PPK chip (if you accidentally programmed it instead of the DK), you can reprogram the firmware by running the flash_ppk.py script inside the software folder.

All the switches are in the correct location. The PPK is mounted correctly on the DK. SB9 is cut on the DK. nrfjprog -r -f nrf52 results in "Applying system reset. Run." I also grabbed an nRF52 DK to try with the same results.

Then there is nothing wrong with the connection to the PPK device. Probably there is something wrong with the software on your computer. Can you try to use the versions specified, or try it on another computer?

Using nRF52 DK instead should not change anything.

Those are the packages that puthon_packages.bat installed. I'll try getting the packages specified.

I tested and it should work with these packages. You have followed the instructions here: infocenter.nordicsemi.com/.../PPK_user_guide_Installation.html ?
