@teastain2 I'll try this and will report back. Thank you.

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:

When I select "Board Info" in Arduino IDE, I receive this:

@teastain2 Unfortunately I'm receiving the same error:

@teastain2 I'll try this and will report back. Thank you.

Trying to run MinimalCameraExample.ino via Arduino IDE, but keep getting the following error. Any ideas on how I "set the partition"?
