Arduino Giga R1 crashes with attach interrupt #789
Description
This Testsketch will cause a "crash" with the Giga Board just after upload ( Red LED blinking ).
According to the Documentation it should work.
but:
As soon as I remove the two lines marked with xyz the Sketch works fine.
crash occurs also:
- when using pin 52,53 instead of 40 / 42
- when using pin 40 or 42 exclusive
- seems independant from number of attached Interrupts/Pins
???
Thanks for any Hint.
