edge trigger interrupt not properly working on ESP32S2 using esp-idf 4.4

Postby Viper89 » Thu May 12, 2022 7:00 pm

Hi all,
Development Setup: ESP32S2,esp-idf version 4.4
I am trying to use interrupt on gpio pin.
Interrupt comes at every 10 msec, shown in attached image. I toggle one GPIO in ISR of gpio.
We are not able to see corresponding toggle pulse on each occurrence of ISR.
is there any issue of allocation flag used in gpio_install_isr_service() ?
One will get following info in attachment:
1. Sample code
2. Logic Analyser output
3. ESP IDF SDk configuration file
Please guide me to resolve the issue.
