Hello all.
My Teensy 4.1 is sitting on the bench with only header pins attached.
I can load up serial monitor in the Arduino IDE and see that an old sketch is running and sending messages.
I can't upload, times out and usual program button push doesn't get things going. But more interestingly I can't wipe it by holding the program button for any amount of time. If i hold the button i get no flash from the LED at all.
If i hold the program button on bootup the teensy goes into a double flash (maybe 2hz) sequence that i haven't read about before but it does prove to me the button works.
edit: I have tried this with just usb power and no pc that could be feeding data and that doesn't get the wipe/blink process going either.
Any ideas what this is, or should i bin it.
Thanks.
Gavin.
