IRQ sender for my personal IP

Hi, I wrote a personal IP which will send IRQ to HPS(Liunx) in some situation. I'm planning to write the LKM to use that IRQ. But parameter setting confused me a lot. Could you guys ...

Hi Alex


The Interrupt sender setting is referring to the input signal that you have.

input: 16bit control register, 16bit timer flag register

The signals are associated to the interrupt.

Like it is required as part of the interrupt. E.g. after interrupt you would either get data or set data to the IP.

The clock are required to sink the communication between the HPS and IP.

You need to use the Avalon MM to communicate between HPS and IP.

Jingyang, Teh

    Hi,

    In that case, in the IP interrupt sender setting,

    my "Associated addressble interface" should be my IP master(which is a Avalon MM bridge),

    then what's the "offset" and "bridges to receiver" stands for?

    Reguards.
