    We compiler experts are not familiar with the Halcogen tool.  I'll move this thread to the TMS570 forum.

    Thanks and regards,

    Hello,

    Based on the error messages I suspect you are using the wrong command line for the compiler.  The error message indicates you are trying to compile for Cortex M3 and without floating point support.  The command line for the compiler should respect both the proper Cortex R4 architecture (-mv7R4) and presence of FPU (-vfpv3D16).  

    Regards,

    Karl

    Silpa,

    The Intvecs.asm routine has to be compiled in ARM mode (32bit)
    Please check the option for this file.

    If your project is compiled for thumb2 mode (16 bit) you have to make an exception for this file.

    In CCS project, you can right click on this source code and specify this option. (see screen shot)

    Regards,

    Jean-Marc
