Hi Nick,
Yes, I tried that after I posted. I get a bit further then, the debugging starts, it hits the breakpoint in main() and when I click run, or step, the session crashes with a lot of log msgs.
After that the communication is dead again and the only way (so far) to get it working again is to force the internal ST boot loader.
It complains about a communication failure but as far as I know nothing has changed in ST connections.
I wonder if something really died or some HW issue in either the GN or the ST.
openocd: Polling target stm32wlx.cpu failed, trying to reexamine
Here are some more log msgs.
