if I use pinMode(), esp32 will keep rebooting, serial output like this:

if I comment pinMode(), everything goes well. But I need to asset it since without it, digitalWrite() will not work.

can anyone help? Thank you so much!

well, I solved it. It was because of that I use the wrong pin names. I should use "D2" but not "2". Thanks so much.
