Following your note to Daniel Gustafsson and the contents of <confdefs.h>, I
edited
 <RTEMS-srcdir>/c/src/tests/sptests/sp32/init.c to add the line:

"#define CONFIGURE_MICROSECONDS_PER_TICK
RTEMS_MILLISECONDS_PER_MICROSECOND(xx)"

before the line: "#include <confdefs.h>" 

I still fail 'sp32.exe' for values of xx between 1 and 5000.

Was this the correct way to configure my psim's reported speed? What test
would be more suitable for me to calibrate this constant?

Thanks.
