How to Debug HardFaults on ARM Cortex-M MCUs

Jun 16, 2021 By Memfault In Memfault

No matter your use case or how sophisticated your hardware is, faults happen on embedded devices all the time for a variety of reasons. Maybe it’s something easy like a reproducible NULL pointer dereference you hit during development or maybe it’s something more subtle like memory corruption or divide by zero faults that only exhibits themselves in zero-g, high temperature, weak magnetic field, or noisy RF environments!
