Hi @zepjau. I am having ESP32-S CAM and I am having similar fatal error.
I have set to define the module as CAMERA_MODEL_WROVER_KIT in Arduino IDE. For the communication of the module with the PC, I am using an FTDI USB to TTL converter. I have setup "ESP32 Board" by Arduino Board Manager. I want to test the "CameraWebServer" example code (Arduino IDE->File->Examples->ESP32->Camera->CameraWebServer) with my ssid and password, but it is giving error while uploading after successful compilation. The error is as per following :
Code: Select all
Sketch uses 2594790 bytes (82%) of program storage space. Maximum is 3145728 bytes.
Global variables use 56256 bytes (17%) of dynamic memory, leaving 271424 bytes for local variables. Maximum is 327680 bytes.

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
I checked if there is anything coming on Arduino Serial Monitor. For that, I opened the Serial Monitor and reset the module. The output is as below :

PSRAM Initialization Failure
ESP32-CAM-MB
It shows the MicroSD Memory Card that I have inserted is detected and it is also able to decide how much memory the MicroSD memory card has which is 30543MB here. The PSRAM fails to initialiaze it says. This output I have checked many times.
Thanks
