CCSv4 BIOS 6 Link Error

Eddie3909
Guru 10385 points

Other Parts Discussed in Thread: SYSBIOS

CCSv4.1.2.00027

BIOS 6.21.3.21

I'm merging my SRIO driver built from the DIO lib into a MessageQ IPC project and what built stand alone with DIO doesn't link in the IPC project (I copied the DIO driver into the IPC project).

I "think" the issue is the macros used in the cslUtils.c file (its been trimmed and renamed to HwMgr_srioUtils below). the cslUtils.c file uses several macros

Hwi_enable()

Hwi_disable()

Hwi_eventMap()

Hwi_clearInterrupt()

etc

that for some reason won't link to my project.

Any suggestions?

Cheers

    Hi

    I modified the DIO cslUtils.c includes to use BIOS 6 in hope that the compiler was getting confused and searching BIOS5 instead of BIOS 6.

    I removed the following includes

    //#include <hwi.h>
    //#include <swi.h> 
    //#include <sem.h>
    //#include <c64.h>

    and replaced them with

    #include <ti/sysbios/knl/Swi.h>
    //#include <ti/sysbios/hal/Hwi.h>
    #in    clude <ti/sysbios/family/c64p/Hwi.h>

    Doing so got rid of a couple more linker errors, but it still can't find these

     undefined                                     first referenced                                    
      symbol                                           in file

     _ti_sysbios_family_c64p_Hwi_eventMap__E       ./Common.cluster/HwMgr.module/src/HwMgr_srioUtils.obj

    Unfortunately I now get the dreaded redefined error I had in this thread.

    http://e2e.ti.com/support/embedded/f/355/p/52404/185974.aspx#185974

    Consequently, removing hwi.h was not the solution to getting rid of the error below.

    Update

    A solution has been found!

    The .cfg was missing the Hwi module. I got it from the "Available Packages" and selected "Target Specific Support"->C64P->Hwi, right clicked and selected "use module".

    Builds fine under RTSC Build-Profile = whole_program

    Even better, the IPC MessageQ now works.

    (Thanks Piyush)

    Cheers
