ESP32-Cam No Response and Unable to Program - Timed out waiting for packet header I recently purchased an ESP32-CAM but have had no luck in programming the board or getting any response whatsoever. I first tried to program it using the an FTDI programmer and the Arduino IDE (following the steps from this tutorial: https://randomnerdtutorials.com/esp32-cam-video-streaming-face-recognition-arduino-ide/). 

I used this exact wiring diagram:  but got the Timed out waiting for packet header error message. This was with the jumper on the FTDI on the 3.3V section.

Other things I've tried: 
-Moving jumper to 5V, powering ESP from 5V pin
-Powering ESP from external 5V source (Arduino pin)
-Powering ESP from external 3.3V source
-Switching computers (Linux and Windows)
-Programming board directly from Arduino (bypassing FTDI)
-Various combinations of pressing/holding reset button during flash process

The other thing is that there is no LEDs that turn on when the board is powered. I couldn't find a concrete reference online that said an LED turns on when the device is on, but I assume the one LED would at least flash or something. Also monitoring the serial output with putty during boot did not yield any output. I'm all out of ideas and I am just starting to suspect that the board is completely dead. Any ideas would be appreciated, thank you.
You're right. There is no LED when you power up your ESP32 cam. So this is normal.

Try to power it with the 5V, so you can power it from your USB instead of the 3.3V regulator of your FTDI. The ESP just need 50mA when in programming mode, so it should not be a problem for your FTDI.

Do you see anything on your serial output? Once you connect it in this way, you should set the baudrate to 115200 on your serial terminal and see some characters. 

Then, try to program it.
Once you see the output "...___...", press the reset button! Since you are just connecting RDX and TDX, you have to manually press "RESET" on your ESP32 module.

At this point the ESP will reset and enter in the programming mode.
