Hi there
I recently attempted to use my esp32 camera with the CameraWebServer code that the Arduino IDE offers in the sample menu. but I'm experiencing the following issues.
I ran into a problem using port com3:
An error with serial exception occurred: Put a timeout in writing.
Note: PySerial is the source of this error. Most likely, the hardware connection or drivers are the issue rather than esptool itself.
Upload failed: uploading error: status 1 exiting
Nevertheless, I ran into an issue when I switched to port com9:
A deadly mistake happened: The ESP32 could not be connected: No serial information was obtained.
Upload failed: upload error: exit status 2.
Is there someone who can assist me?

To identify the correct port for your ESP32-CAM board, follow these steps:

1. Disconnect the Arduino board's USB cable from your PC.
2. In the Arduino IDE, go to Tools > Port and note any listed ports.
3. Close the Tools menu (this refreshes the port list).
4. Reconnect the Arduino board to your PC using the USB cable.
5. Go to Tools > Port again. If a new port appears, it's the one for your Arduino board.
6. Select the new port and try uploading your code again.

If you saw a new port appear at the last step, select that port from the Tools > Port menu and try uploading again.

After trying the suggested steps,
1. Did you notice a new port in the Tools > Port menu at step (6) that wasn't there at step (3)?
2. If so, was the upload successful after selecting it?

Also, are you using the FTDI?
