Hi, I got this error in MotionDetectionRGBExample sketch. I'm using CAMERA_MODEL_AI_THINKER

I think I fixed it by adding esp_camera_fb_return(frame); in loop after delay(30);
Did you find the esp_camera_fb_return(frame); fix in the comments of the post?
Did you find the esp_camera_fb_return(frame); fix in the comments of the post?
no, I just tried because the error LoadProhibited was pointing to EXCVADDR: 0x00000000 so a NULL pointer, so I tried to "release" the camera buffer and it works
Ok, I need to update the post to include this. You're not the first to encounter this error.
Hello, I have just started using this code - https://github.com/eloquentarduino/EloquentArduino/blob/master/examples/CameraMotionDetection/CameraMotionCaptureExample/CameraMotionCaptureExample.ino with an aithinker board and ov7725 camera. I am getting a very similar printout from the board after uploading:

What is the best way to resolve this?
Thanks,

Motion detection moved to my new blog. You should really refer to that post --> https://eloquentarduino.com/projects/esp32-arduino-motion-detection
Thanks @eloquentarduino that's useful to see. Do you have an idea why I might be having that issue?
I can run the first example in your blog fine, it captures images. The second example which involves the saving the image to SD card is not working. I am using the following board settings in the Arduino IDE 
Your blog is really useful, thanks for the code :)
Strangely, it just worked and now outputs the following
Camera init OK
Best quality jpeg file size in bytes: 7428. It took 125684 micros to encode
However I am not finding any images on the SD card.
The example on the blog saves the images to SPIFFS filesystem, not an external SD card. It should work by replacing
auto file = filesystem.writeBinary("/capture_best.jpg");with
File file = SD.open("/capture_best.jpg", "wb");Not tested yet.
Of course, you have to initialize the SD card as always in the setup method.
