Since the TOD sdk software seems to depend on timer support in addition to the TOD hardware, you may have to put the following line in your appconfig.h file:
 
#define INCLUDE_TIMER
 
Apparently both const.c and config.c are declaring the same variables.

Subject: [motoroladsp] Quadtimer and TOD combined usage giving linker error.

Hi,
      I am using codewarrior for firmware development of 56F827. I
want to use Quad timers and TOD so for that I have modifed appconfig.h
file.

#define  INCLUDE_QUAD_TIMER    /* Quadrature timer support */
#define  INCLUDE_TIME_OF_DAY

      After including both I am getting linker error      

"Warning : Illegal immediate operand format.
Immediate operands must be prepended with #.
vector.c line 634   30u

Link Error   : Multiply-defined: "FqtExtAMode" in const.c
Previously defined in config.c

Link Error   : Multiply-defined: "FqtExtAMask" in const.c
Previously defined in config.c

Link Error   : Multiply-defined: "FqtDeviceMap" in const.c
Previously defined in config.c

Link Error   : Multiply-defined: "FqtNumberOfDevices" in const.c
Previously defined in config.c
"

I have gone through const.c and config.c and came to conclusion that I
will have to comment QUAD_TIMER declaration.

Could anybody tell me what is the reason I am getting Linker errors?

My analysis for the above problem:

I found following declaration in config.c

#ifdef INCLUDE_TIME_OF_DAY
      #include "timerdrv.h"
     
      posix_tTod POSIXTodStaticContext[1];
      posix_tTod * POSIXTodContext;

      #ifndef INCLUDE_TIMER
            posix_tDevice * POSIXTimerContext;
            const char * POSIXDeviceList[1];
            const int    qtNumberOfDevices;
            const qt_tQTConfig qtDeviceMap[1];
            const UWord16      qtExtAMode[1];
            const UWord16      qtExtAMask[1];
      #endif

#endif

Doea it means that I will have undef QUAD_TIMER declaration.

Thanks and Regards,
Nitin
