J-Link IDs were found in registry.

[Stayhungry]

I want to use nRF Connect v2.1.0 to debug. But i faild to connect the correct J-link because the nRF Connect choose the wrong J-Link IDs on the COM. So i can just change the COM to use. Is there a solution that i can clean the registry for the COM?? Thanks.

You can select the COM port when you click on "Select serial port" in nRF Connect

Hi,Sigurd.Thanks for your help.

it show me the log when i click on "Select serial port".

"Multiple J-Link IDs were found in registry for COM10:[J-link ID1, J-link ID2]"

I found ID2 is the J-link SN on DK . But the nRF Connect choose the ID1, as the result, the correct emulator cant be connected. Maybe i used the ID1 J-link before.

I've tried changing the COM port of J-LINK to COM24, it does work. But the UART terminal cannot monitor such a large number of ports.

I have no idea how to solve it.

What UART terminal are you using?

I recommend Termite.
