hi ,

am using cyclone IV qsys "ip compiler for pci express" ,if we enable CRA avalon slave port in parameter setting, then if i export CRA am not seeing any cra_irq in instance generated , but cra_irq (output) is only visible in system inspector , how to access that cra_irq, it is output but u mentioned interrupt input to the pci core will available .

same happened when i used the single DW completer , rxm_irq (input) is visible in system inspector not visible in system content tab in qsys. how to use that rxm_irq

also help me where mailbox registers available, and how to use write to it, in user guide they had given a2p_mailbox and p2a_mailbox with some address ,where to write those addresses, help me . If any reference design for interrupt or tutorial help me.

thanks,
