Flash page is locked

Official Hardware Mega Due
1

Hi,
I have Arduino Due and I have used it a couple of days but suddenly I see the following error:
"Flash page is locked An error occurred while uploading the sketch" when I upload a program.
I see some suggestion to press Erase and Reset knobs and release the after uploading starts.
I did this and I can get the Arduino work again. But the problem is I need to do this always when I want to run the program again. This is really frustrating and impossible in the real situation.
Anyone has any idea how can I resolve this issue?

Best,

Mahmood,

There are two different issues :

  • One is the error message "Flash page is locked" which should be solved via an erase and a reset BUT this doesn't work for some boards (see a recent thread about this issue). IMO uploading a sketch to clear GPNVM bit 0 via SAM BA should solve this issue if the security bit is set.

  • Another one is the DUE won't restart after a power off. See this thread reply #61 and #79:
    Due won't start after power off-on, have to reset - Arduino Due - Arduino Forum
    AFAIK this second issue seems resolved with the brand new version of the DUE you can see in the Product section of this web site:
