using quickstart I can't find the DK

[tldr]

There are two USB ports.  IMCU and nrf5340.  I had a lot of trouble with bad cables but i found one that works and I find that I have a jlink drive that pops up so I know there is a good connection.  However, when I run the quickstart, it does not find the DK.  vscode also does not find the DK.

It tells me to provied the log.  however there isn't much to the output.

Any suggestions?  I'm not sure what I've got wrong.

On another computer, I was able to find the board, the kit shows up and it says not supported yet and continues searching.

What firmware does the DK come preloaded with?  Is the quickstart not compatible with this DK?

[tldr]

I see the device in vscode - peripheral_lbs builds fine; I am getting the following when I try to program:

I found that the version of the jlink software that is installed does not work.

I found the latest jlink software does not work.

I used the above and I am programming.  The machine I had trouble with prior also programs successfully after rebooting.

Hi David

Sorry for the delay in response, its been national holidays here in Norway. I cannot say that I have seen this issue before but if I understand you correctly then changing Jlink version fixed the issue for you?

[tldr]

that's correct. it seems the one installed does not work out of the box.

i found a hint to downgrade jlink and that worked.
