Calling gpio_config() with intr_type = GPIO_INTR_HIGH/LOW_LEVEL causes reboot
ESP32S3, esp-idf-v5.0.1 - GPIO inputs with interrupts Calling gpio_config() with intr_type of GPIO_INTR_XXXEDGE or GFLAG_INPUT_CHANGING has worked fine for me, and the interrupt functions work as expected. However, after reading the ESP32 Errata section "The ESP32 GPIO peripheral may not trigger int...

I've been struggling with this for the past week (ESP IDF 5.0.1, ESP32-S3-WROOM-1-N8R2) and my conclusion is - When the i2c hardware transmit fifo (32 bytes) is empty the ESP32 transmits random(ish) garbage - ...
