INTC with BIOS problem

Other Parts Discussed in Thread: SYSBIOS

Hi,

I am trying to use BIOS & INTC together .But it never works.If I use INTC in BIOS free environment,there is no problem.

Is there any way of using INTC & BIOS together ?

Bios version : 06_32_01_38.

Device : TCI6618

    Bharti,

    There is a module called ti.sysbios.family.c66.tci66xx.CpIntc which is used for programming the INTC.
    Unfortunately there is a bug in your BIOS version and you would have to upgrade to at least version:  06_32_04_49

    Judah,

    There is no problem with the CSL API - CPINTC(used to configure INTC)..Problem is occuring only with INTC API (used to configure HWIs).

    If I remove BIOS functions from the system ,it works fine,but I want to use INTC (CSL API) & BIOS together.

    Bharti,

    Yes, I understand that the issue isn't the CSL APIs, but rather getting those APIs to work with BOS.
    What interrupts are you trying to configure with CPINTC?

    I'm pretty sure that the CSL APIs for CPINTC and BIOS can work together.
    My other suggestion was that since BIOS has its own APIs to support CPINTC, it might be just as
    easy to use the BIOS CPINTC APIs.

    Judah,

    No matter what interrupts I want to configure with CPINTC & INTC.The thing is just that as I call the function CSL_intcInit(&Context),the system gives a run time error.

    I read somewhere that INTC is a different kind of CSL library unlike other CSL APIs & BIOS & INTC can be used together but with "CAUTION".

    so I wanted somebody to explain how can the problem be resolved & what caution one needs to take for same.

    Regards,
