I'm testing the camera on my T-SIM7080G S3. I'm running the standard CameraWebServer script (see below) and have added the necessary chip/camera attributes. I've had everything working just a week ago. Now suddenly the camera doesn't supply an image to the server.
The script complies and uploads correctly. The camera (OV2640) configures correctly too, and I receive no errors. However, all I see is the above broken image thumbnail.
Things I've Tried:
- Different usbc power cables
- Using battery power
- Bought new OV2640 cameras
- Different camera server scripts
- Multiple combinations of reset & boot buttons
- Cleaned ribbon cable connector
I'm stumped! Anyone have ideas?
Script I'm using. CameraWebServer.ino:

#include <WiFi.h>
#include <Arduino.h>
#define XPOWERS_CHIP_AXP2101
#include "XPowersLib.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
