Sure.   Attached are a makefile and a trivial C program that I was using 
yesterday to test the timekeeping stuff.

Just put them in a directory, run 'make timetest', then copy the 
timetest executable to somewhere that it can be accessed by your 
microblaze board (via an NFS mount or whatever).  Then you should be 
able to just run it with ./timetest or whatever.

You must ensure that the uClinux-dist that is pointed to by the 
makefile, has to be "current", and properly configured etc.  I think 
Yashi explains this in his instructions on the OutOfTree compile Wiki page.

Cheers,

John
