Thanks awneil. Yes I realize that, I've found a solution in SEGGER Foruns. I'll leave it here for further reference if another comes by looking for it:

"in Embedded Studio project options which J-Link to use for which instance under Project-> Edit Options->Debug->J-Link->Host Connections
Change that value to USB S/N where S/N is your serial number e.g. USB 12345678"

in - https://forum.segger.com/index.php/Thread/5217-SOLVED-Linux-JLink-How-to-use-multiple-JLink-under-Linux/?postID=19309&highlight=debug%2Brtt%2Binstances#post19309

I just haven't been able to do it simultaneously with JLinkExe and JLinkRTTClient in the command line. But I'll look for a solution and will post it if I find anything useful...

Again, the process for debugging multiple targets would not be specific to nRF52 - as far as SES and the JLink stuff are concerned, it's just another Cortex-M4.

Hopefully the Segger forum is a bigger pool to draw from - plus Segger staff do engage there ...

I guess your suspicion would be correct =P

I suspect that Linux is a minority interest here ?

Thank you Simonr . I asked here because I'm debugging a nordic device and I would think that someone would already have done this before me. So there should be knowledge in this dev. community about how one could debug multiple devices in the same computer. It surprises me no one has manifested knowledge of how to do this in Linux. Thank you.

As Andrew says, if you are able to see this list in SEGGER, but not able to choose a device from it, you should contact the SEGGER support team, as there is nothing we can do about this.

Best regards,

Simon

If it can show you the list, but not let you choose one, then that's a Segger issue.

Thank you awneil. I rarelly use Windows, althought I have a dual boot machine. Most of the development is done on Linux. In Linux I can also see a list of the serial numbers. But I can't choose or pick one in the applications I mentioned in my original post.

Regards

On Windows, when there's more than 1 JLink connected, it shows you a list of their serial numbers and you have to pick one.

This is a Segger thing - not specific to Nordic - so you may be better asking on the Segger forum.

If you do cross-post, be sure to give links in both places.
