Hi
I post Adeos+xenomai to S3C6410 SOC with Linux-2.6.35.9, and the Linux
kernel and Xenomai are ok when system boot(according the printed
information when system boot)
when I input "xeno latency", the information in screen is
== Sampling period: 1000 us
== Test mode: periodic user-mode task
== All results in microseconds
Xenomai: registered exported object dispsem-832 (semaphores)
warming up...
Then the system is hang (ctrl + C does not work). Through print debug
information in code ,I guess the problem is in "display(in
latency.c)->rt_sem_p"
Can somebody help me to analyse the problem? Thanks

If you are porting xenomai to S3C6410, you should have a look at the
I-pipe porting guide:
http://xenomai.org/index.php/I-pipe-core:ArmPorting
the fact that the display task waits for the semaphore is probably not
the problem at all.
