Hi,
I try to connect sensors to esp32 board. when connecting a sensor, for example, DHT11, but it happens with others as well the board enter into a loop of boots with the following error
I get that a lot with several of my boards. Try going through various different ESP32 board types, and also try supplying it with more power (higher amps/additional power supply instead of USB).
You also want to stay away from GPIO12 and GPIO14 during boot time.
They control core voltage and SPI timing. Best advice is don't pull them up or down.
See ESP32 Data Sheet which discusses this.
