Parallella Community

I had written a code for the epihpany device few days ago. It was running fine, but since few hours whenever i run the code,it freezes and a blank screen appears. Is there a problem with my code? Here is the github link...

Please Help!

I did not spend too much time reading your code, but noticed that in file e_task1.c, function getmat(), you return a pointer to a variable allocated on the stack within function getmat(). That is not going to be reliable 'C' code. While you could return a pointer to a "static" variable allocated within your function, that is only because "static" variables are not allocated on the stack. With the variable declared "static" all invocations of the function would share a single allocated variable. This is really not so much an issue with the Parallella, but rather an issue with the 'C' programming language.

Since the screen goes blank instead of locking up that leads me to believe that the board does not freeze, but is shutdown to protect itself from overheating.
Does the board get sufficient cooling, do you have a fan?

I am using a fan and have no problems as of now, thank you
