Re: [ts-7000] Problem with RTAI user test

My guess is that one of the libraries
isn't being loaded.  There are different modules used for kernel and
user space -- and order matters.

I have not had much luck with the rtai-load
script, which is supposed to load libraries automatically based on a .runinfo
file.

Try loading the libraries manually:
        /sbin/insmod
/usr/realtime/modules/rtai_hal.o
        /sbin/insmod
/usr/realtime/modules/rtai_ksched.o
        /sbin/insmod
/usr/realtime/modules/rtai_lxrt.o
        /sbin/insmod
/usr/realtime/modules/rtai_sem.o
        /sbin/insmod
/usr/realtime/modules/rtai_mbx.o
        /sbin/insmod
/usr/realtime/modules/rtai_msg.o

and then load the latency tests manually:
        ./latency
&
        ./display

BTW... the contents of the .runinfo
file in user/latency are
        latency:lxrt+sem+mbx+msg:!./latency
&;sleep 1;./display;popall:control_c

which is where I got the manual order.

I don't know if manually this cleans
up everything nicely... so you might have to kill the latency app manually.
