Software reset
To perform software reset of the chip,
cution of the program will stop, both CPUs will be reset, application will be loaded by the bootloader and started
again.
Additionally, esp_register_shutdown_handler()
to be called prior to restart (when done by esp_restart()). This is similar to the functionality of atexit
POSIX function.
Reset reason
ESP-IDF application can be started or restarted due to a variety of reasons. To get the last reset reason, call
esp_reset_reason()
reasons.
