2.6.18 Miscellaneous System APIs
Software reset
To perform software reset of the chip, esp_restart() function is provided. When the function is called, exe-
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() function is provided to register a routine which needs
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() function. See description of esp_reset_reason_t for the list of possible reset
reasons.
