Hello,
I faced a problem with Xenomai xntimer when using the
http://download.gna.org/adeos/patches/v2.6/nios2/adeos-ipipe-2.6.30-nios2-1.2-00.patch
patch.
xntimer uses the ipipe abstractions for hrclock and hrtimer and relies
on the constants
#define __ipipe_hrtimer_freq 1000000 /* 1 us */
#define __ipipe_hrclock_freq nasys_clock_freq
defined in include/asm-nios2/ipipe.h to do a final adjustment.
The two definitions above will fail, if either the hrtimer is not
clocked with 1Mhz, or
the hrclock is clocked with another frequency than nasys_clock_freq.
I am quite new to ADEOS, but guess that
#define __ipipe_hrtimer_freq na_hrtimer_clock_freq
#define __ipipe_hrclock_freq na_hrclock_clock_freq
is a better choice. At least for me this solves the problem.
