Tool/software: TI C/C++ Compiler

Hi everyone,

I am trying to program a CLA of a TMS320F2838x with tables loaded into the CLA ROM, but a lot of warnings appear due to the CLA Table symbols loaded into the ROM section:

If I have a look into the *.map file I can see that the CLA Table has loaded as it should be. Here you can see the symbols fitted to the address range of the CLA ROM (0x01001000 to 0x01001FFF):

page  address   name

abs   01001e50  CLAsincosTable_TwoPiDivTABLE_SIZE
...

I understand that the CLA data ROM address range (25 bits) exceeds the CPU address range (16 bits) but the compiler should be ready for this situation, isn't it?

For further understanding of the configuration I used, the compiler version used int his project is TI v20.2.2.LTS.

I also followed all the configuration steps in the file C2000Ware_3_02_00_00\libraries\math\CLAmath\c28\docs\CLA_MATH_LIB_UG.pdf and my project is configured this way:

  • CLAmath.h is included in the project
  • Correct CLA2 selected:
  • Libraries included to the Linker:
  • Predefined variables CLA_MATH_TABLES_IN_ROM=1 and CLA_C=1 activated in the Linker section.
  • *.CMD file without CLA1mathTables section.

Futhermore, I have tried to load the CLA math Table to RAM, without all the ROM configurations, and the error is gone, logically.

What should I do with that warning?

Thanks.

    Hello,

    The CLA Data ROM should be mapped at 0xF000-0xFFFF in order for the CLA to access it.   The locations you have mentioned is the memory mapping for the C28x CPU.  (Ref memory map page 240 of the data sheet).  

    Your screenshot of the libraries did not come through - are you using the ROM symbol library?  If so there may be an issue with it.  In the meantime I will check with a colleague to see if it uses the CLA mapping. 

    Regards

    Lori

    Jahel,

    My colleague confirmed that the revA CLA ROM symbol libraries are using the C28x address.  We will file a bug to get this fixed.

    Until that is done, you can use the rev0 CLA ROM symbol libraries. \libraries\boot_rom\f2838x\rev0\rom_symbol_libs\cpu1\claDataROM

    The CLA items didn’t move between the two revisions.

    Best Regards

    Lori

    Hi Lori,

    I tried the Rev0 CLA ROM symbols and worked perfecly. Thanks for opening a bug to get this solved!

    Kind regards,

    Jahel
