ESP32-C3 GPIO interrupt is not triggered during light sleep enabled

Postby ermacv » Thu Apr 28, 2022 8:12 pm

Hello guys. Did somebody try the following setup for ESP32-C3 with esp-idf (tried 4.4v and the latest master):
* FreeRTOS in tickless mode
* DFS with enabled light sleep
* GPIO input interrupt

I have a custom board with external 32 khz quartz for light sleep support, the pin that is used for interrupt handling has a pull down resistor.

So the problem is that GPIO interrupt and ISR function is not triggered with enabled light sleep but the same code works without DFS light sleep.
Also tested manually calling light sleep start function and the result is the same.
