[Nucleo_F401RE] Serial conneciton freezing constantly

Post by AdamN » Tue May 05, 2020 9:06 pm


I am having trouble with the virtual serial port of the nucleo. It seems to either be crashing or freezing every 5 minutes or so. Requiring a full power cycle to get it working again. The reset button on the board doesn't work when it's in the frozen state.

I have written short programs in the REPL, which seem to work ok for the time they're running, but once I stop them the board freezes almost immediately. I haven't written any proper programs for it yet as I want to fix this issue before spending time with a longer task.

If the reset button doesn't work, then it sounds like you have a hardware issue. There isn't anything that the software can do to override the behaviour of the reset button.
