Bug CpIntc ROV View ?

Hi Clement,

We've reproduced your issues and confirmed that ROV is reading the wrong controller. We've opened up a bug:

SDOCM00112160: CpInt's ROV is always showing CIC0 

We'll address this is a future release.

I was able to get ROV working with a couple changes.

1. Add the following somewhere in your application (e.g. main). Have coreNum be an global Int.

Int coreNum;

Void main(Void)
{
    extern cregister volatileUInt DNUM;
    coreNum = DNUM;

2. In <bios_install_dir>\packages\ti\sysbios\family\c66\tci66xx\CpIntc.xs replace the following lines

    try {
        var controlReg = Program.fetchStruct(CpIntc.RegisterMap$fetchDesc,
                                             controller.elem,
                                             false);
    }

with 

         var coreNum = Program.getSymbolValue("coreNum");
    var coreNumValue = Program.fetchArray(
                {type: 'xdc.rov.support.ScalarStructs.S_Int', isScalar: true},
                coreNum, 1);

    try {
        if (coreNumValue < 4) {
            var controlReg = Program.fetchStruct(CpIntc.RegisterMap$fetchDesc,
                                                 controller.elem,
                                                 false);
        }
        else {
            var controlReg = Program.fetchStruct(CpIntc.RegisterMap$fetchDesc,
                                                  controller.elem + 0x4000,
                                                  false);
        }       
    }

So ROV looks at coreNum on the target and then decides which controller to use. Note the code I'm asking you to change in the CpIntc.xs file only impacts ROV. It does not impact any target code.

The fix in a future release will be along these lines.
