ppk broken ?

[erltot]

Seems PPK is broken, it measures ~70mA no matter what I connect it to, even only measuring on a DK in shutdown.

I suspect this happend during measuring on a custom board, an j-link debugger was connected to the custom board and it may have caused a ground loop (?)

SW3 was set to DK as illustrated in Fig.11 in the user guide, but perhaps it should be set to EXT when connecting a debugger to the custom board ?

Or maybe it's not related and I just got a faulty board..?

Have you made sure that you set up the PPK like described in this link here?

Also, which version of the PPK are you currently using? Which version of the PPK software are you using?

[erltot]

1. Yes, exact like figure 1, but with debugger as well as illustrated in my second picture in the question

2. PCA63511 rev 1.1.0 2017.16 602F589E nRF6707 Power Profiler Kit - Software files 1_1_0

Note that it was working fine for a good while before it broke

Have you taken a look at this case?

[erltot]

Yes seems like he had a faulty board. Could my error be caused by a ground loop from having both debugger and PPK connected to USB on the same comupter though?

I guess it could have been a ground loop, yes. Can you think of any other errors you might have made that led to the ppk becoming faulty?
