Migrating Example projects from dsplib to ccsv4

Other Parts Discussed in Thread: TMS320VC5505, SPRC100

HI,

I have recently got hold of a TMS320vC5505 ezdsp usb and am having problems importing legacy projects from dsplib, after importing the legacy project from the dsp lib when I try to buil it I get the following error:

>> ERROR: Only --ptrdiff_size=16 is allowed for small memory model
C:\Program Files\Texas Instruments\ccsv4\utils\gmake\gmake: *** [C:/TiDoc/c55dsplib/dsplib/EXAMPLES/sqrtv/Debug/TEST.obj] Error 1
C:\Program Files\Texas Instruments\ccsv4\utils\gmake\gmake: Target `all' not remade because of errors.

this happens for all examples any solutions for this issue?

If I change the memory model to large I get the following error:

fatal error: file
   "C:/Users/aimtias/Documents/workspace/sprc100/dsplib_2.40.00/EXAMPLES/sqrtv/
   ../../55xdsp.lib<sqrtv.obj>" specifies small memory model, which is not
   compatible with large memory model specified in a previous file or on the
   command line

Thanks in advance.

    Hi Ali,

    Please see this article:

    http://processors.wiki.ti.com/index.php/DSPLIB#Q:_How_can_I_rebuild_the_DSPLIB_v2.40.00_library_for_a_newer_CPU_rev._3.x.3F

    Using these instructions, make sure to use --memory_model=large

    You could also compile your project for the small memory model, and in the Build Properties, change ptrdiff_size to 16:

    Hope this helps,
    Mark

    any idea what causes this.

    This warning usually means the library is empty.  It could also mean that it is corrupted.
