Hello There,
I'm trying to use the esp32 cam as in this link ESP32-CAM Video Streaming and Face Recognition with Arduino IDE | Random Nerd Tutorials. the code compiling is ok. my problem is in loading the code, I get this error:
Serial port COM14
Connecting......................................
A fatal error occurred: Failed to connect to ESP32: No serial data received.

Arduino: 1.8.19 (Windows 10), Board: "ESP32 Wrover Module, Huge APP (3MB No
OTA/1MB SPIFFS), QIO, 80MHz, 921600, None, Disabled"

keeping in mind I made a mistake in the connection at the beginning, that I connected the VCC pin of the FTDI programmers to the ESP32 VCC pin, not the 5v one (I hope it isn't dead), after connecting it to the 5v pin I still can't load the code.

Your advice is very appreciated.

Hello there,
At first use for my ESP32s-CAM, by mistake, I connected the VCC pin of the FTDI programmers to the ESP32 VCC pin, not the 5v one. Did that kill it?
from the first time I used it, I didn't see the built-in led on the board blanking, even when I tried to connect ESP32s-CAM to Arduino UNO it didn't blank.
Any advice please, I just want to know if is it still alive.

Most likely, if the VCC pin of the FTDI programmer carried 5 V.

ok thanks.

You might want to try to reseat the camera connector in the socket. If reseating does not work, your board is toasted.

The serial port is detected however same fatal error is seen. pls help.

Finally after hours of trying to connect and reading all thread here and elsewhere on the internet, I made it. Simply download CP210x Windows Drivers with Serial Enumerator (CP210x USB to UART Bridge VCP Drivers - Silicon Labs). That's it!!!!!!!!!!
