[ECOS] Problem in FIQ with ecos for arm(at91sam7x)

[Mervin J]

Hi,
The main reason for using FIQ is that,
    In Hardware, The external interrupt pin is connected to FIQ pin and 
also we want to get the interrupt within few ms.
 I succeed by handling  as GPIO Interrupt. But, While handling as 
FIQ,there is some stack overwrite issue.
One more question is that, Whether I can redirect the FIQ to a simple C 
routine and return to the User mode without more complexity.

Thanks a lot for Your suggestion in handling FIQ.
