Esp32cam Failed to connect to ESP32: Timed out waiting for packet header

Question

I've just recieved my very first esp32cam (AI THINKER) today and I was excited to test it, but I'm unable to upload any code to it. I'm always getting the following error:

Failed to connect to ESP32: Timed out waiting for packet header

So, the FTDI I'm using is the FT232r with the following wiring scheme

FTDI Wiring

How I reproduce this error:

• Plug everything
• Order IDE to upload the sketch
• Wait for the "connecting" text
• Press the RST button

Also:

• Plug everything
• Press the RST button
• Order IDE to upload the sketch

I've already tried:

• Switching to 3.3v (plugged on 3.3v pin)
• Using external 5v power supply (plugged on 5v pin)
• Using another computer
• Swapping RX TX
• Trying in different upload speeds
• Holding RST button
• Switching board between ESP32 Wrover Module and AI Thinker ESP32

I'm I doing something wrong or there's just something faulty?

Answer 1

This was solved by using other jumpers. It seems one of the jumpers used in the wiring was faulty.
