CCS/LAUNCHXL-F28069M: Warnings on Example_F2806xLaunchPad

Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hi! I'm developing an solution for the board LAUNCHXL-F28069M based on the examples found in the C2000Ware v2.00.00.03 folder.

Trying to build the solution Example_F2806xLaunchPad provided by the C2000, I get the following warnings:

remark: linking in "IQmath_fpu32_coff.lib" in place of index library
"IQmath_fpu32.lib"
warning: cannot resolve archive
C:/ti/C2000Ware_2_00_00_03_Software/libraries/math/FPUfastRTS/c28/lib/rts280
0_fpu32_fast_supplement.lib to a compatible library, as no input files have
been encountered; build attribute information from input files is needed to
determine library compatibility

I suppose this warnings are related to the fpu libraries, which I need to use in this project I'm currently working on.

I'd like to know what this errors mean and how could I solve it. Thanks!

    That's fine anyway the example doesn't use FPUFASTRTS or  IQMATH .

    The remark is to show that the example is that since the IQMATH now have 2 kinds of libs like eabi vs coff the library being mapped in the example is coff.

    Similarly , the rtslib is actually an indexed lib and the options for the lib are driven from the example which calls it.

    if there is a need to use the lib please change the linker options to use the _coff viant of the rts lib.

    Regards.
