sam4l xplained pro - security bit activated

Mon Jun 23, 2014 4:57 pm

Hello,

I have purchased a sam4l xplained pro board, I have loaded the example FLASHCALW1 and it had activated the security bit.

Now the flash is locked and I cannot load another program because the debugger does not recognize the board and says
"05 50 39 094:  Could not activate interface"

How can I reset the security bit ?

Found the solution.

Just press the erase button from the memory section.
