How to enable FIQ on OMAP3430 Emulator device

Hi,

I am currently trying to trigger a FIQ and collect some info on its handler.  My device type is Emulator and based on OMAP3430.

I have already configured MPU_INTC.INTCPS_ILRm register FIQNIRQ bit for an FIQ interrupt, and updated vector_fiq for its handler. Just testing it. I see cpsp F bit is 0, but FIQ always can not be generated. Seems it need configure SCR or something else.

Anyone know how to enable FIQ and can give some clues?

 

Thanks

Andy
