IRQ and Generic tristate controller

Hello, I have a Cyclone 10 project that includes a Nios2 processor implemented in Platform Designer. One of the components in the design is a LAN91C1111 interface implemented through a Generic Tri-State Controller and connected to IRQ 1.

When I "Generate HDL" in Platform Designer and then "Generate BSP" in eclipse, the resulting line in system.h for the IRQ is incorrect (#define LAN91C111_IRQ -1).

If I manually edit the line is system.h (#define LAN91C111_IRQ 1) the lan controller functions properly.

What step am I missing to get the correct IRQ passed from the Generic Tri-State Controller into the Nios2 environment (system.h)?

    Hi Michael,

    I see that you filed two similar cases on this topic, which is 05831210 and this one(05831221). Since it is a duplicated case, may I request to close this case and support you with case number 05831210 as it may cause confusion?


    Thank you and hope to hear a reply from you.


    Kind Regards,

    Kelly

      Yes, that would be great. I was not sure which group was appropriate.
