Magesh,

This sounds like a crash in an interrupt handler.  The two 0's sent to
Control_SystemStart are actually function pointers the first called when quit
is invoked, the second function should be called every second.  I don't
understand why the board is crashing (it works find here, but maybe if you put
a function pointer (the function should return 1) in the second parameter you
will see if that function is called.  I hope this helps.
