Unable to connect to Power Profiler Kit PPK2 - faulty hw?

Sacha

Hello,

I purchased my first nordic semiconductors device, the PPKII, from Farnell.

I just received it today and installed the required software (nRF Connect on macOS, and the recommended SEGGER J-Link version).

But unfortunately I am unable to connect to my PPK2 device. The device simply does not show up at all.

When I connect to the “USB data / power” port and toggle the “power” switch to "ON", both LEDs slowly flash green (fade in / fade out effect).

However the device is nowhere to be seen in the Power Profiler app.

- I did install the recommended version of segger software (V9.24a)

- the device can not be seen in macOS system report / USB

- I also tried to connect it to a different computer, on a linux host, the device is not listed in lsusb and nothing appears in dmesg

- I tried with the switch in the "off" position, I tried the other "USB power only" port, I tried 3 different USB cables, same result

- I tried to make sure no other device of any kind is connected to the computer

- I tried changing my USB hub / trying without a hub on the linux computer

Should I simply return it and ask for a replacement or is there something I'm doing completely wrong?

Thanks!

    Hi Alexandre,

    Could you maybe try the following as well.?

    Disconnect all other nordic devices from the computer, turn off the kit and remove it from the plastic by removing the four screws. Insert USB to J2 (USB DATA/POWER). Short a connection between GND (e.g on the four pin power output header) to TP34 on the PPK2. While holding the jumper cable, turn the kit on and remove the jumper. Now the PPK2 should be in bootloader again.

    Open the PPK app, and select the device which is now just a serial number. When selecting it, the user will be prompted to program the application and it should now be working again.

    Best Regards,
