Need help with warning in PlatformIO ESP-IDF for ESP32-S3 timer ISR
Hi guys I facing this issue with my esp32-s3 timer isr i am using platformio esp-idf any clue to solve this warning?

Solution
This represents memory regions inside the internal RAM (IRAM) of ESP32. I don't use PlatformIO but usually because of the deprecated
timer.h build failed. In your case, it seems like IDE couldn't locate the relevant libraries. Please try this example code to test and also follow instructions from the readme file https://github.com/espressif/esp-idf/blob/master/examples/system/esp_timer/main/esp_timer_example_main.cGitHub
