I had a problem using timer interrupts in the past. I had the 
interrupt flag set of the timer but ARM core didn't see it! I tried 
resetting and everyting else but didn't work.......after 2 hours, I 
repowered the board and everything worked just fine!!! For some 
reason, reset != power cycleing

loading up the vectors correctly at program load or you are 
corrupting your program when loaded in RAM.
