Hi guys,

I´m using nested interrupts and it is working fine when I run my code at RAM (MEMMAP = 2). 

When I try to run my code at FLASH I receive a data or prefetch abort exception.

I´m using IAR compiler and the keyword __nested to declare my interrupt function. 

If I declare my interrupt function without the __nested keyword everything runs ok.

Does anyone had any similiar problem ?

Thanks,

Did you look at the code ? Did you set a breakpoint in your interrupt 
routine
and look what's going on ?

Hi there,
The problem is solved, I needed to increase the size of the stack when 
running at Flash.
Thanks,
