Hello, can someone tell me what I need to do, to use external 32KHz crystal in ESP32-S2 and Arduino IDE. The crystal is good, the code written in Visual Studio Code works fine on the external crystal after I selected it in the configuration.

How can I recreate this using Arduino IDE?

So far I've ...

Hello, anyone has an idea why the internal RTC with an 32kHz crystal is drifting constantly in the ESP32-S2?

I am using this code to run and calibrate an external crystal: (Arduino IDE)
rtc_clk_32k_bootstrap (512);
rtc_clk_32k_enable (true);
rtc_clk_slow_freq_set (RTC_SLOW_FREQ_32K_XTAL);
for ...
