Hi,
ESP-CAM -> ESP-CAM
GPIO0 -> PULL DOWN to enter into download mode
GPIO1 -> RX
GPIO3 -> TX
GND -> GND
3.3V -> 3.3V (you can also power the ESP-CAM using the 5V pin)
I apply the necessary connections like you said, there is an issue with the pin layout you suggested. I think the correct layout should be like this:
ESP-PROG -> ESP-CAM
GPIO0 -> PULL DOWN
GPIO1 -> TX
GPIO3 -> RX
GND-> GND
3v3 -> 3v3
GPIO3 and GPIO1 should change their places. Apart from this, I got an error message while flashing my empty program into ESP-PROG and the message is:
Code: Select all
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
*** [upload] Error 2

The terminal process "C:\Users\omerf\.platformio\penv\Scripts\platformio.exe 'run', '--target', 'upload', '--environment', 'Release'" terminated with exit code: 1.
I connect GPIO0 to GND via a 10k resistor like this:

I tried holding RST down while flashing but it did not work.
This is my config file for vscode with platform io
Code: Select all
[common]
platform = https://github.com/platformio/platform-espressif32.git
board = esp32dev
framework = arduino
monitor_port = COM5

upload_speed = 921000
[env:Release]

Do you have any idea why this might occur?
My queries are:
