PSP lib builds for C6747

I am using version 01.30.00 PSP for the C6747 device.  I notice the lib folders already contain pre-built libraries with the .a674 extension.  I opened up the mcasp project in ccs4 and built the Debug and Release configurations but I do not get the same output.  The only thing I changed was the extension to a .lib file (so the new build wouldn't overwrite the old one).  For the Debug build, the pre-built lib file is 341,712 bytes while my build is 344,842 bytes.  For the Release build, the pre-built lib file is 170,954 bytes while my build is 92,392 bytes.

Why is there is difference and what do I need to change to get the same build(s) as what shipped with the TI PSP?  This also happens with SPI and probably other peripherals as well.

Also, I don't see any difference between the 'i' (e.g. instrumented) configurations and non-'i' configurations.  This might be related to the 'Mcasp_DEBUGPRINT_ENABLE' define symbol mentioned in mcasp.h but I could not find this symbol anywhere in the source code.  I've noticed a similar issue with the SPI peripheral and haven't checked the others.  Is the 'i' configurations just legacy stuff that hasn't been cleaned-up?

thanks,

Mike

    The size of the libraries/binaries generated depends on the versions of code generation tools, DSP/BIOSTM  and other dependencies.

    The support for instrumented libraries does not exist currently in the PSP drivers. This is just a place holder.
