RE: Programmer error

I believe I have solved my issue. I was using a USB hub to connect to the Segger J-Link. When I reconnected it directly to my "new" computer, the issue went away. I believe there must be a timing issue using the Hub that manifested itself exactly as shown above in Keven's information. Background: the problem occurred after changing computers, now running Windows-10, and then re-installing the nRf connect, python, programmer..etc. Needless to say, It took me a while to try changing USB ports!

Hi!
I wouldn't know, since Kevin never responded again. If you're having the same issue, make your own ticket on DevZone and link to this case to give more information.
Best regards,
Heidi

Thank you!
[quote user="Heidi"]Could you take a screenshot of what you see when clicking the "No devices available" drop-down menu? [/quote]
Could you do this as well, please? When your board is connected and powered on.

Hi!
Could you take a screenshot of what you see when clicking the "No devices available" drop-down menu?
And could you please provide me with the full log output by clicking this button.
Best regards,
Heidi
