Hi,
working without any problem. Please help to solve the problem.
We can't help you with so little information. Give us more information. Whats your system consist of, which eCos version do you use, which configuration (HAL only, Kernel etc.) Have you wrote the FIQ handler in assembler, how is the FIQ handeled (via the eCos interrupt system or dedicated?) What did you tried until yet to find the bug, post your code if it's not to big. (Or at least the important parts.) If in C - post also the initialization of the FIQ.
