Hi,

When I try compiling the motor module for vxWorks-mpc8548 I get an "unknown bit order" error (see below).

It looks like the CPU type for vxWorks-mpc8548 is PPC32 because if I add PPC32 to the motor.h file, it compiles ok.  
I set the bit fields to be packed MSB first.  Is this correct?

/* Define, from top to bottom, how bit fields are packed. */
/* This works for gnu, SunPro, MS Visual C. */
#if defined(_WIN32) || defined(_M_IX86) || defined(_X86_)
    #define LSB_First (TRUE)  /* LSB is packed first. */
#elif defined(__i386__) || defined(_armv4l_) || defined(_X86_64_) || defined(__APPLE__)
    #define LSB_First (TRUE)  /* LSB is packed first. */
#elif defined(i386)
    #define LSB_First (TRUE)  /* LSB is packed first. */    
#elif defined(sparc) || defined(m68k) || defined(powerpc)
    #define MSB_First (TRUE)  /* MSB is packed first. */
#elif (CPU == PPC604) || (CPU == PPC603) || (CPU==PPC85XX) || (CPU == MC68040) || (CPU == PPC32)   /***** I added PPC32 CPU type here *****/
    #define MSB_First (TRUE)  /* MSB is packed first. */
#else
    #error: unknown bit order!
#endif
