Reprogram Firmware on Power Profiler Kit II

[mujeeb]

Hi,

I accidentally opened and subsequently programmed the PPK-II in Bluetooth Low Energy module startup. The programming didn't complete but resulted in an error. Now the PPKII is totally off and the LEDs are not turning on at all when I connect it to USB. I think I need to reprogram it. I tried to load the hex file from Git Hub via the Programmer application on nRF Connect but that didn't work. I will appreciate it if anyone can point me in the right direction to do this.

Thank you.

Hi, can you try what Øyvind suggests here: https://devzone.nordicsemi.com/f/nordic-q-a/75163/ppk2-not-turning-on/309793

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.

After running through these procedures, the PPK will begin a slow red LED "breathing" sequence.  However, no serial device is available in the PP software v3.5.5

In device manager, I do see "nRF52 SDFU USB (Com21)"
