CCSv3 & DSP/BIOS V5 or CCSv4 & DSP/BIOS V6?

I'm a bit confused about which tool versions I can and/or should be using!

We are developing a device that includes both an OMAPL-137 and a C6455.

We don't have any existing investment in TI software and therefore if feels like a bad idea to start using old tools i.e. CCSv3 and DSP/BIOS V5, but AFAICT it's not that simple!

Is it correct to think that we shouldn't start using the new tools for these devices?

There appears to be an OMAPL-137 PSP for BIOS V5 but not V6. DSP LINK appears to only support BIOS V5 on the OMAPL-137.

Although there's no PSP for C6455 there are other tools i.e. NDK or RapidIO MSGQ that we might want to use.

I think it makes sense to use the same tools on both platforms.

    Matt,

    CCSv4 actually includes two versions of DSP/BIOS.  5.40 which is binary compatible with the BIOS 5.33 that the OMAPL137 PSP is built for and BIOS 6 which is a brand new version of BIOS.  The easiest thing for you to do will likely be to use CCSv4 + BIOS 5.40.  If you import projects from the OMAPL137 kit it should automatically convert them to BIOS 5.40.

    Regards,

    Hi John,

    Sorry, I did know that CCSv4 & BIOS 5.4 was an option and (without knocking CCSv3 too much) it is probably better than CCSv3 & BIOS 5.3.

    But, just to be clear, BIOS *6* is *not* an option for OMAPL-137(?).

    I feeling a little disappointed because I read the stuff about BIOS 6 and thought it looked much better (I was particularly interested in the native execution).

    Thanks,

    Matt

    Matt,

    CCSv4 + BIOS 5.40 is the easiest option.  BIOS6 definitely has some nice features (native execution, better support in debug displays...) however by default it uses a new API so you would need to run it in backward compatibility mode to attempt to use PSP.  We have done some migration exercises in moving OMAPL137 projects to CCSv4/BIOS5.40 and it is pretty smooth.  Moving to BIOS6 would be a lot more involved.  I don't have much experience with doing that.

    Regards,

    John
