Because GPIO0 is a strapping pin for entering UART flashing mode on reset, care must be taken when also using this pin as EMAC_TX_CLK. If the clock output from the PHY is oscillating during reset, the ESP32 may randomly enter UART flashing mode. One solution is to use an additional GP...

The ledcAttach function sets up an LEDC pin with a given frequency and resolution. The LEDC channel will be selected automatically.bool ledcAttach(uint8_t pin, uint32_t freq, uint8_t resolution);This function will return true if the configuration is successful. If false is returned, an ...
Pin configuration and the number of pins.To properly use the ESP32 in your projects, you need to have access to the board pinout (like a map that shows which pin corresponds to which GPIO and its features). So make sure you have access to the pinout of the board you’re getting. Oth...

target/esp32: Fixed incorrect sampling of the ESP32 bootstrap pin GPIO12. When the flash is empty, the TDI pin remains floating and may be sampled at an incorrect level by the bootstrap circuit, which can cause the flash to operate at an unexpected voltage. ...
