Diagnostics for Cobra?

I am running a Cobra 1 board. Was testing program successfully for many hours and days without issue, then program suddenly stopped running. Have deployed new version of code that just blinks a light. But nothing. Can someone point me to any documentation on some more basic testing or board health indicators?

Thanks.

When you said there’s nothing, do you mean that only your code does not work? Do you succeed to see your board using Visual Studio?
