GPO34 was connected to a WS2812 by me, but it doesn't work properly. I moved the LED control pin to GPIO and it will work.
Thank you for your help.

当我重新添加IO21和IO34的定义及配置函数后，编译下载进板子。
似乎例程中有过程使用了IO34，导致程序超时了：
部分log：

[ 1891][V][esp32-hal-periman.c:160] perimanSetPinBus(): Pin 21 successfully set to type LEDC (9) with bus ...

thank! Your judgment is correct.
I just tried to comment out the code related to the functions of these two pins, and the image can now be set to the maximum screen.
It seems that the functions related to these two pins are affecting the operation of the board.
Sorry, due to company information ...
