rtc_gpio_deinit(gpio_num) doesn't work

[Chandini]

Hi,

I am working on a project using ESP32 Wrover-B where I am using IO4 (RTC_GPIO10) and GPIO36 (RTC_GPIO0) for wake-up out of light sleep. esp_sleep_enable_ext1_wakeup() is used for wake-up detection. After wake-up, IO4 needs to be used as a digital GPIO. On https://docs.espressif.com/projects/esp ... pio_num_ti , it's mentioned as follows -

After wake up from sleep, IO pad(s) used for wakeup will be configured as RTC IO. Before using these pads as digital GPIOs, reconfigure them using rtc_gpio_deinit(gpio_num) function.

However, when I tried to reconfigure the RTC_GPIO10 as digital GPIO using rtc_gpio_deinit(GPIO_NUM_4) and then use it as an output pin and set it high, it doesn't seem to work. Any idea if this API works or has been deprecated?

Thanks!
