Have I damaged my nRF52832 Dev Kit?

Rick

I have been analyzing the current consumption of my nRF52832 dev kit today using both a multi meter and an oscilloscope with a resistor. I'm not sure what I exactly did that lead to this, but now my board constantly uses 80mA. It can still be programmed and it does seem to run. Did my board get damaged somehow? If so, can it still be fixed?

Edit: What could have happened is that the dev kit was powered for a short time without a jumper on P22 (also no short on SB9 nor resistor on R6). Not sure what this could do to the board.

Edit2: The issue was temporarily fixed by replace the nRF52832 chip on the dev board but now it's back again. Not sure what I'm doing wrong.

    My colleague helped me replace the chip on the dev board which fixed the issue. We didn't figure out what caused the damage in the first place. I power the board through the P21 header at 3V but also tried using the battery. I used both a 10 and 100 ohm resistor. My only guess what could have happened is that the power supply I'm using spiked above 3.6V for a short moment.

    Edit: It just happened again :( Any idea what I'm doing wrong?
