I can't use the arduino IDE to burn the program to esp32 cam, and when I upload it, I get the following error message：

I updated esptool and the original error is gone, but there is still another error：

But I've already linked to the ESP32 cam

OK, I solved the problem. I updated esptool using this command.

pip install pyserial esptool

Also, I think the source code of this repository seems to have some problems.

I can't successfully burn it into the eap32 cam. Finally, I strongly recommend using the Arduino IDE2.0 version, which is very easy to use.
