Im using arduino due for my current project. Initially i didnt have problem in uploading my sketch it works fine. But after few times now im having "flash page locked" issue in my due. I have 3 dues all has same issue now. I cant upload any of my sketches. What is the problem and how i can i upload a sketch now??

Try if you can unlock Flash regions this way:

Hi Ykciv,

There are several ways to address this issue. On first instance I'd try the following:

Keep pressed the erase button. After 1 second, press the reset button while keeping the erased button also pressed, wait 1 more second. Then, release both buttons. Finally, try to program Due again.
