TMS320F28379D: Issue related to linking IQ math lib (F28379D)

Siddharth Iyer

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi, 

I am trying to use the IQ math library with the TMS320F28379D controller. Initially, I was getting an 'unresolved symbols remain' error whenever I called any of the IQ functions. To resolve this, I tried to add IQmath.lib under Project > Properties > C2000 Linker > Filer Search Path. A screenshot of this window is included below:

After this, I was getting the following warnings when I built the main file through the FLASH:

I then tried debugging and when I hit run in the debug window, the code stopped executing and this is what I see on my screen:

I am attaching the full linker cmd file below. If I am not mistaken, some lines pertaining to the IQ math library need to be added to the cmd file. I want to run this in the FLASH and not in the RAM, and I have no idea where to find the appropriate code lines. Please advise.

    Hi Siddarth,

    Can you try the following

      1. Linker Command File Configuration: Add these sections to your linker command file: 
        • /* IQ Math Tables in Boot ROM */
IQTABLES  : origin = 0x3F0C30, length = 0x0B5  
IQTABLES2 : origin = 0x3FE78,  length = 0x08C  
IQTABLES3 : origin = 0x3FE8C,  length = 0x0AA  

SECTIONS
{
    /* Allocate IQ math areas: */
    IQmath           : > FLASH      PAGE = 0        /* Math Code */
    IQmathTables    : > IQTABLES,  PAGE = 0, TYPE = NOLOAD
    IQmathTables2   : > IQTABLES2, PAGE = 0, TYPE = NOLOAD
    IQmathTables3   : > IQTABLES3, PAGE = 0, TYPE = NOLOAD
}
      2. Project Configuration:

        • Add IQmath library to project

        • Ensure correct library version (FPU32 if using floating-point)

        • Add proper include paths

      3. Common Issues and Solutions:

    • Unresolved symbols: Check library path in linker settings
    • Memory allocation: Verify IQ tables are properly mapped
    • Runtime errors: Ensure proper initialization

    Hi Siddharth,
    That was just an example. 

    Please replace the memory regions that you have available on the device and you can update the linker command file. Essentially just was trying to show that you'll have to add the IQ math tables to your flash linker file.

    Best,

    Hi Ryan,

    Where can I find a sample FLASH linker cmd file? I looked in the IQ match directory of the C2000ware folder, but I could only find a sample RAM cmd file. Thanks in advance.

    Hi Siddharth,

    We have a sample FLASH linker cmd file in C2000Ware regarding F2837xD. See C2000Ware/device_support/f2837xd/common/cmd/2837xD_FLASH_IQMATH_lnk_cpu1.cmd:

       /* Allocate IQ math areas: */
   IQmath			: > FLASHB, PAGE = 0, ALIGN(8)            /* Math Code */
   IQmathTables		: > FLASHC, PAGE = 0, ALIGN(8)

    You currently had no output section assignments for IQmath and IQmathTables, which I believe would direct linker to use an default address in RAM and therefore invalid code access to that section.You can double-check this by looking into the generate .map file and see if the IQmath variables and functions got placed in a RAM address specified in the linker.

    But just try inserting the above output sections into your linker and see if the problem still persists.

    Best,

    Hi Sen,

    Thank you very much! I wasn't aware of this directory in C2000Ware, everything works now.
