I have built my own Arduino Due Circuit board. I am having issues with it randomly locking up. I have researched the libraries and have ruled out any issues with them such as the Wire library. I am wondering could an issue with the power supply cause a brown-out that would lock it up. The only way to recover is to unplug it and plug it back in. It can run for 1 hour 1 week or months before it locks up. Does anybody have any idea what could cause this issue and how I can resolve it? Could the fuse or lock bits being set wrong cause this type of issue?
