I think having read and tested a lot of discussed topics here, but still I can not make run the PPK on the DK52 board (PCA10040).
I have prepared the HW by cutting SB9, placing both switches to 'DK' at the PPK and set the COM switch to 'DK'.
When starting the application and connecting the DK52 with the installed PPK I see messages like 'Validating firmware for device with s/n ....', 'PPK closed', 'Opening device with s/n ...', 'PPK opened', 'Initializing the PPK', 'Segger serial: 68....', 'SEGGER speed: 2000 kHz', 'SEGGER version: J-Link OB-SAM3U128-V2-NordicSemi compiled Mar 17 2020 14:43:00' and 'PPK started'.
But when I press then the Start-Button, I get a 'PPK command failed' message and an 'Average started' message in the log, but nothing to see at the screen...
I saw that for ony topic in the forum the nRF Connect SW V2.70 helped, but not in my case.
What can I do next?
I'm literally having the same issue with the fresh installation of nRF Connect and Power Profiler. Could it be a general problem? I had to create my own post, with more detailed steps and screenshots.
Can you verify the state of the 3 switches on the PPK?DUT select: DKPower select: DKCOM: DKWhat reversion of the PPK do you have? (white label)
sorry for my late replay . I was off...
I have checked the switch settings; the DUT and the Power select switches are in DK position and the COM switch seems also to be at the DK position - at least I can measure a direct connection (0 Ohms) between the source of the switch and the contact on the left upper side near the marking DK at the PCB...
What could it be then?
