hello ,everyone!
I`m trying to patch the 2.6.25 kernel with Adeos Ipipe.And the xenomai
version is xenomai-2.4.4.tar.gz.
But when I execute " ./latency -t0 -T60 -p100 -h " on the s3c2440 board,there
are some errors :
== Sampling period: 100 us
== Test mode: periodic user-mode task
== All results in microseconds
warming up...
latency: failed to set periodic, code -110
latency: failed to pend on semaphore, code -110
Any idea about that ?
Thank you!

The latencies on s3c24x will not allow you to run with a 100us period.
Also, you should use xenomai 2.5.6.

I`d tried to run with a 100000000us period or 10000000us ,that`s the same
problem.Actually,the error was thrown out by rt_task_set_periodic
().Especially,when I use rt_task_set_periodic() or rt_task_wait_period() in
my program,they can`t return 0.
But I`ll try to use xenomai.2.5.6.
Thank you!
