I'm finding the FIQ handle method in i.MX257.
Please share the code if you have.
Actually I want to make the interrupt with around 100ms period.
The interrupt was not operated normally when I applied the GPT and EPIT.
So I want to use the FIQ in our product.
I know Linux might not satify the periodic Interrupt due to Linux Scheduler and Interrupt Handle Flow.
I could see the phenomenon in GPT and EPIT Timer, but I think FIQ has the better performance in Interrupt.
Could you give me how to apply FIQ in i.MX25?
