while(1);
{
    something;
}

is exactly the same as:

while(1)
{
}
{
    something;
}

In other words, what you have there is an infinite loop followed by a scoped block of code (which will never be reached).

Get rid of the semicolon and it should fix that particular problem.

You must not end the while(1) with a semi-colon dude. Because that's a null statement you wrote in there.
