Trouble with ESP32-S3 and CameraWebServer

[istrian]

Hello,
Im working on my school project and i keep running into a problem with CameraWebServer and ESP32-S3. Im using ESP32-S3 N16R8 Development Board (https://www.aliexpress.com/item/1005006095863180.html?spm=a2g0o.order_list.order_list_main.35.6b7b1802oLfUvJ#nav-specification) with OV2640 camera.
I want to run the CameraWebServer code from arduino IDE.
This is how i have configured the board:

Here is the code:
`#include "esp_camera.h"
#include <WiFi.h>

//
// WARNING!!! PSRAM IC required for UXGA resolution and high JPEG quality
// Ensure ESP32 Wrover Module or other board with PSRAM is selected
// Partial images will be transmitted if image exceeds buffer size
//
// You must select partition scheme from the board menu that has at least 3MB APP space.
// Face Recognition is DISABLED for ESP32 and ESP32-S2, because it takes up from 15
// seconds to process single frame. Face Detection is ENABLED if PSRAM is enabled as well

// ===================
// Select camera model

Serial.print(WiFi.localIP());

}

void loop() {
// Do nothing. Everything is done in another task by the web server
delay(10000);
}`
The error that Im getting from serial monitor:

I have tried:
I have ESP-CAM, and Im able to get the code uploaded and the CameraWebServer working with the same OV2640 camera from ESP32-S3 but the problem is i cant get face recognition running as it has ESP32 inside it and it doesent support face recognition with it (that is why i switched to ESP32-S3)
Switching the USB port on my PC

Thank you for your help in advance.

[me-no-dev]

the error suggests that the driver can not find the sensor. That is usually due to bad pin config. make sure that your sccb pins are correct

[istrian]

Yea, thank you, that is true as when i select different board model it works, do you know where can i find the exact pin config for my board as i cant find the data sheet for it?

[Jason2866]

In the schematic diagram the are listed.

[istrian]

Yes, thank you, i replaced those pins with the right ones and it works, for anyone who might have the same problem here they are:

I just want to thank you for this post and the solution.

@istrian Hi,
I know it has been few months since the answer to this post but I was wondering if your code still works? I said this because I too has recently bought the same exact ESP32-S3 module on aliexpress and has configured everything including your camera pins and the same exact code as here but I still get the

E (571) esp_core_dump_flash: No core dump partition found!

Could this be related to the newest version of Arduino? Alternatively the board is seen by default as: 4d systems gen4-esp32 16MB Modules (ESP32-S3 r8n16) but I have changed to ESP32S3 Dev Board for the sake of trying out your code since you mentioned it worked last time. Any Clue?

Thanks heaps in advance

Hey, I cant upload the code as i have wiped my pc and no longer have access to it, please try viewing the forum: https://www.reddit.com/r/esp32/comments/1797tr4/esp_core_dump_flash_no_core_dump_partition_found/

Hi istrian, thanks heaps for getting back to my question. Really prob the most important reason I asked was because I was using the same module as you bought from AliExpress and it’s an N16R8 based whereas the link you suggested above is about the Wrover modules. Did you really get the web server to run? Because I have tested 4 modules already and while they work for light applications they all fail to use PSRAM when I attempt to use camera, the is also a malloc buffer error along with PSRAM ID check error is 0x0000000,

It seems the external 8MB PSRAM has to do with the error! It has been over 2 weeks and I would really like if someone can shed some light! Thanks in advance

[istrian]

Try making a new thread if you havent already so more people can see your issue.
