I am having a similar issue. I am flashing two dev boards with an identical sketch. One shows expected behavior, and the other shows the behavior indicated above.

You might want to try erasing all the flash memory in the failing devices and then flashing your application again. Stories I have seen before where the identical program runs fine in one device and fails in another have occasionally been resolved by a full flash erase.

Thank you for the info.
Tried erasing the flash. Flashed again after erasing. Still same issue. Changed the USB cable still same issue.

Hello,
Did you manage to solve the issue? Mine is facing the same problem.
In addition is getting hotter if I use the RF peripheral.
If I only blink an led , I have no problem.
I also checked the wiring. No short and all the voltages are in the expected range.
Good luck !
