Program branches to illegal ISR - naay...@gmail.com - May 29 14:54:36 2008

Hi all,

When i run my program in RAM or Flash memory, it branches to illegal ISR routine. compilation
and build is ok. No errors appeared. but if i run my program again, it shows the status as
running,but no output. what is the reason for it? 

Has anyone faced this thing before?

Please help

Thanks

Have you tried single stepping to see when it is happening. You can 
try disabling all interrupts first and then start enabling one by one 
to see with. In example projects provided by TI/Spectrum digital all 
the ISRs are initialized with default vector table. 
If you are running your own code on custom hardware then stop feeding 
input signals if any and start giving one by one.
