esp32cam - Timeout waiting for VSYNC error 0x20003

[mit-vincode]

Hello! I'm doing the ESP32CAM firmware and trying to get the IP address via SerialPort further. I do the firmware through the programmer, grounded IO0, pressed RST at the time of filling. The sketch is filled in correctly on the board. Next, I open the SerialPort Arduino IDE, press RST and expect to get an IP.

1. If IO0 is connected to the ground, it hangs on the message:
   rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
   waiting for download

2. If IO0 is disconnected from the ground, it first passes normally to entry 0x400806b4, then the error crashes: Camera init failed with error 0x20003
   What am I doing wrong?

Error when IO0 is disconnected from the ground:
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

This question has already been asked here before, but I have not found an answer. Thank you in advance.

GPIO0 zero must be disconnected from any wire after programming because this pin drives the cam clock and does not tolerate any capacitive load

As @Jason2866 says, if you have an AI-THINKER board (or ArduCam) you must let GPIO 0 float after programming.
Most other boards avoid this mistake and assign a different pin, if in doubt look at the pin definitions in the code to see which number the camera xclk is assigned to.

I did it, the IO0 pin is disconnected. However, when you click the Reset button in the Serial Port, an error occurs

[E][camera.c:222] skip_frame(): ‘

Try this firmware it is verified working well and uses latest Arduino Core from here.
You can easily flash via Webbrowser (Chrome or Edge) from here https://tasmota.github.io/install/

Guys - it worked for me! Thank you guys! Thank you very much))

However, in continuation of the topic. I changed the camera to another one - after pressing RST an error occurred:
E (993) camera: JPEG format is not supported on this sensor
Camera init failed with error 0x106
How to fix it?

[Jason2866]

You have to use a different webcam sketch. Tasmota webcam does not support cameras without JPEG support.
