I am using the Jetson nano to catch a pulse as an interrupt and execute some functions. While testing with pulse generated from an ESP32 microcontroller everything was working fine. However, when I started testing using a 24V pulse and an isolator board to convert them to 3.3V pulses, the Jetson crashes as soon as the first pulse comes in; it freezes at first and then restarts. But because the signal was the same and the only new thing was its source, I removed the low pass RC filter on the isolator board and tried again. It was able to take the interrupts and didn’t crash. However, now the isolator is producing bouncing signals which is increasing the pulse count. Does anyone know why did the jetson crash with an external RC filtered pulse input?
I am using TI ISO1211 isolator chip.
