Question on compiler switch: Are "-mv6400+" and "-mv64+" identical?

Other Parts Discussed in Thread: TMS320DM6433

Hello,

I have a quick question with regard to "-mv" compiler switch to specify CPU model. Are "-mv6400+" and "-mv64+" identical? Some documents use "-mv6400+" and other "-mv64+", and there seems no clear description on "-mv64+".

Thanks.

They are the same. The option -mv6400+ is the standard documented option. The option -mv64+ is quietly accepted as the same, and that will not change.

Thanks and regards,

I am a little confused ont he same issue, is -mv64plus another synonym.

I have a dm6433 what should I use, the compiler is pretty relaxed about mv6433, mv6433+ or mv6499 for that matter?

The full name is TMS320DM6433. That is the number for the device you are using. This device contains a C64+ DSP core. The compiler does not target a device, it targets a CPU core. Thus, you use -mv6400+.

Thanks and regards,

HI George,

I did play around, using the information from spru198 I think, but I ended up calling the wrong irq disable amongst other things so I just went back to -mv64+.

It would be nice if the compiler could spit out a definitive list fromt eh cmd line.
