xdc Reference Error in .tcf

Other Parts Discussed in Thread: SYSBIOS

Hi,

I am building a 6748 image with code composer 4 in Windows XP env, and also have xdctools installed.
now, I am trying to use the exception module, by adding it in .tcf via the following statement:

var Exception = xdc.useModule("ti.sysbios.family.c64p.Exception");

however when I opened tcf via configuration tool, I got an error: ReferenceError: "xdc" is not defined.

any tips? is there any config steps that should be done before using xdc?

(I see that the path to xdc was updated)

thank you

Hezi.

Hezi,
Are you using DSP/BIOS 5 or SYS/BIOS 6? TCF script are used in DSP/BIOS 5, while 'xdc' is a SYS/BIOS 6 object.

Exception support for C64+ is described in SPRU403, in Appendix C.

Sasha,

thank you very much. I have looked through this doc, and my only question now is whether there is a way to have EXC_internalHook point to my own function?
is there api or via TCF or other means to do this? or do I need to modify the relevant EXC src file?

Regards,

Hezi.

Hezi,

You cannot specify the EXC hooks thru graphical or textual configuration. You need to do it in your C code. And you don’t need to modify EXC sources to do this.

For example, define your handler:

Void myInternalHandler(Void)
{
/* handle internal exception… */
}

And then set the EXC_internalHook pointer in your C code, like this:

EXC_internalHook = myInternalHandler;

Now when an exception occurs, myInternalHandler() will get called at the end of the EXC_internal() function. The source for EXC is provided in the DSP/BIOS install, for example in:

bios_5_41_11_38\packages\ti\bios\src\exc

You can do something similar to configure the other EXC hooks too.
