ESP32-CAM PSRAM Initialization failure and Timed out waiting for packet header Error

If the waiting for upload message does not appear then no work. In other words the ESP32CAM must indicate it is ready for upload before selecting to upload the program in the IDE. I see that the flash LED is on in your photo. The default is off. Could you post an image of the pin side of the connection points? On another note, I have tried several FTDI modules to find they do not all work the same. I went through several FTDI's modules till I got one to work.
