Function esp_idf_svc::hal::sys::esp_wake_deep_sleep

pub unsafe extern "C" fn esp_wake_deep_sleep()

@brief Default stub to run on wake from deep sleep.

Allows for executing code immediately on wake from sleep, before the software bootloader or ESP-IDF app has started up.

This function is weak-linked, so you can implement your own version to run code immediately when the chip wakes from sleep.

See docs/deep-sleep-stub.rst for details.
