Hardware timer causes core dump in ESP32

  1. My goal is: To use hardware timer at frequency of 1000 Hz
  2. My actions are: Using hardware timer and use call back function to collect data from I2C.
  3. The result I see is: Core dump when I flash code
  4. My expectation & question is: Hardware timer should work

You might want to debug the core dump and see what error is crashing the device. Might not be the hardware timer
