I have a brand new development board that is failing to flash the sample programs using nRF Connect Desktop quickstart (Linux/Ubuntu 24.04). Here are the logs:

I also tried a different computer (Windows 11) with the same result.
I found a couple of similar issues:
- RE: Bricked debugger on nRF54L15-DK
- nRF54L15-DK board Segger firmware issue.
I don't think it is a driver issues since I had the same problem on two different computers. I also doubt I am going to have the same luck letting the board sit for 12 hours and magically start working.
So I guess that leaves that my board is defective and needs to be replaced?
