I have implemented Interrupt handling for Free RTOS running on ARM cortex A9 ( Zedboard). I am facing the following problem.
I am able to see that the interrupt line is being raised ( by checking spi_status register for the corresponding interrupt)
But the interrupt is not being caught by Free RTOS
I also see this condition, I can see that for my interrupt the set-enable ( ICDISER) bits are set, but when i raise the interrupt line for that corresponding interrupt, The set enable bits are getting reset. I raise my interrupt when a Free Rtos task is running. This is quite weird and I do not know why the Set-enable bits for that interrupt is being reset when I raise my interrupt line. Any ideas would be appreciated?
I know this question is quite specific to Free rtos, but i am actually un-aware why the set-enable bits for the interrupt is being reset ( quite weird in my opinion), so does not any one know why this happens?
