How to connecting the Power Profiler Kit to a computer and measuring current without an nRF5 DK?

[zhangchi]

In spec "PPK_User_Guide_v2.3.1" ,chapter " 6.6 Measuring current on custom hardware without an nRF5 DK "

I connect PPK to computer as the picture above, micro USB for power supply and J-Link for PPK connection. But the app "nRF connector-power profiler" can only find J-Link but can't find PPK device.

What may cause this problem? Is this connection method right? Or what kind of J-Link we should use?

How are you converting the 20-pin out from the J-Link the 10-pin Debug-in header? Do you have one of these? It is likely that the issue is that the J-Link and the PPK Debug-in is connected correctly.

Best regards,

Simon

The version of J-link is V6.0.

I don't have 10-pin Debug-in header. So I only connect SWDIO, SWDCLK, SWO, VDD and GND by jump wire from PPK to J-link.

I correct the connection from PPK to J-Link. But the nRFConnect still can't find PPK.
