Compiler/TMS320DM8127: FIQ and IRQ Interrupt vectors

John W71

Part Number: TMS320DM8127

Tool/software: TI C/C++ Compiler

I am trying to program the TMS320DM8127 interrupt controller INTC using the Table 14-3 of the SPRUGZ8G–14 Technical Reference document which lists the various registers within the INTC.

Please could you tell the physical memory location of the INTC base address(or point me to where it is declared in the documentation)?

Also please could you tell me the memory address location of the FIQ and IRQ vectors so that I can load these locations with my interrupt handling routines.

Thanks

    Hi John,

    INTC start address is 0x48200000, this is documented in DM812x DM, SPRS712C, Table 3-6. L4 Slow Peripheral Memory Map

    There are no fixed addresses for the interrupt vectors. There are exceptions and trace vectors at fixed addresses, documented in TRM, chapter 4 ROM Code

    Regards,
    Pavel
