Howdy forum,
I'm using T4.0 with StepStick DRV8825 stepper drivers for a while without issue. All of the sudden, I am unable to program my T4.0. I get the following fault:
Interestingly, the T4.0 shows up in Device Manager on the expected port, and runs the last program as expected (minus being able to interface with the serial COM). This is the second T4.0 that this has happened to!
I have verified that the rest of the cable/tool are fine by programming an alternative T4.1 without issue. I can see 3.3V on the power pin as expected (although I haven't scoped it).
Any thoughts on what I can do to debug/recover these would be much appreciated!
Thanks,
Jim

Teensy did not respond to a USB-based request to enter program mode.
