C5515 DSP LIB v2.40 question. How can I rebuild this library package for a newer CPU rev. 3.x and which options to choose? Using readme file do not solve the issue. Executing Blt55xx.bat file only delete the old *.lib file.

Hi John,

Here is how to rebuild the DSP library package for CPU rev. 3.3 with options to choose memory models

1)    Copy and rename Blt55xx.bat in the dsplib_2.40.00 folder. Open with a text editor.
2)    Comment out c:\ti\dosrun.bat (CCS3.3 relic). REM is the CMD line comment (remark)
3)    Specify the path to the most current Code Gen Tools (CGT)
       Download here:  https://www-a.ti.com/downloads/sds_support/CodeGenerationTools.htm#C5500
4)    Add OPTIONS for C5505/15 (cpu:3.3, 5505, 5515 are equivalent) and desired memory model (use --ptrdif_size=32 for huge mem model only)
5)    Change the name of the output library to represent memory model (DSPLIB=55xdsph)
6)    Either double click the batch file or run it from Windows CMD line to see the output...
7)    Include the newly created library file in your project and test it with the DSPLIB examples

Here is how the Blt55xh.bat (also attached

) file should look for C5505/15(cpu:3.3) & huge mem model:

    REM this file is for building DSPLIB in huge memory module on C5505/15

    REM call c:\ti\dosrun.bat

    set CGT_BIN=C:/Program Files/Texas Instruments/ccsv4/tools/compiler/C5500 Code Generation Tools 4.3.8/bin
    set PATH=%PATH%;%CGT_BIN%

    REM Equivalent OPTIONS for C5505/15, huge memory model:
    set OPTIONS= -g -vcpu:3.3 --memory_model=huge --ptrdiff_size=32
    REM set OPTIONS= -g -v5515 --memory_model=huge --ptrdiff_size=32
    REM set OPTIONS= -g -v5505 --memory_model=huge --ptrdiff_size=32

    REM Equivalent OPTIONS for C5505/15, large memory model:
    REM set OPTIONS= -g -vcpu:3.3 --memory_model=large
    REM set OPTIONS= -g -v5515 --memory_model=large
    REM set OPTIONS= -g -v5505 --memory_model=large
    REM set OPTIONS= -g -v5505 -ml

    set DSPLIB=55xdsph
    set SRC=55x_src
    set FILES= *.asm
    set EXT=asm

    REM built library in SRC dir  and then copy to root
    del %DSPLIB%.src
    del %DSPLIB%.lib
    cd %SRC%
    del *.obj

    cl55 %OPTIONS% %FILES%

    ar55 -r %DSPLIB%.src *.%EXT% ..\include\*.h
    ar55 -r %DSPLIB%.lib *.obj
    copy %DSPLIB%.src ..
    copy %DSPLIB%.lib ..
    del *.src
    del *.lib
    dir *.obj >> ..\junk.txt
    del *.obj

    cd ..

See the C55x Compiler's User's Guide for more info on the compiler options.C

Hope this helps,
Mark
