Trying to Understand Blinking LED (Pin 13) Crash 4.1

[banans]

Hello,

I'm writing a program on Teensy 4.1 that will crash and go into a state where the pin 13 LED blinks steadily (~1Hz).

When the crash happens, I don't get any report or disconnect on the serial monitor. The behavior seems like something that's entered an endless loop, but I wouldn't expect to see the LED blinking if that were the case.

Does the blinking have any specific meaning? I've tried Googling but I'm having trouble making a specific enough query.

Libraries I'm using in my code: ChRt, NativeEthernet (UDP), and ArduinoJson. Again, not looking for a specific reason why the crash is happening, just what the steady LED blinking implies.

Thanks!

There is no 'inherent reason' for the LED to blink at 1Hz.

That is only controlled by the sketch uploaded to the Teensy.

Something interesting is happening - but code loaded on the Teensy is causing that behavior ... and the code hasn't been presented ... but somewhere it has code performing that blink action.
