Hello,

Is FIQ supported with DM37x ?

How can I generate FIQ interrupt ?

When I register interrupts on timer, dma, gpio, I always get IRQ interrupt, not FIQ.

Thank you,

Hi Ranchu,

The Interrupt controller is able to steering each interrupt to FIQ or IRQ. The type of interrupt request is determined by the MPU_INTC.INTCPS_ILRm[0] FIQNIRQ bit (m= [0,95]).
You can find more details about interrupt type in the AM/DM3730 TRM section 12.4.1 Interrupt Processing.
