@janjongboom I apologize if this issue has been resolved and I just could not find a resolution. I uploaded static_buffer sketch to ESP32 Cam board and getting ‘panic’ exception. When I decoded the trace I found this
As per all the suggestion in this thread, I converted feature to RGB888 following your repo. I have tested basic web camera code with this board which is working. So my board and fine. I also uploaded the same sketch to Nano BLE sense and it worked. Just can’t get it working with ESP32 Cam. Here is my code.
