Hi everyone,
First of all, I would like to thanks everyone who have helped me!
I finally could make RTAI works! The problem: I used a wrong gcc version to
compile the kernel. I was using gcc-3.4.4 but the TS 2.4 kernel must be
compiled with gcc-3.3. After this, everything works fine.
Now I'm testing RTAI.
I'm beginner in kernel modules programing so I need some help.
I realized that I couldn't use the functions open, mmap and so that TS uses in
examples to access the registers. Than I found that I can do this using the
function outb(value, address). Everything works fine, but is this the right
thing to do?
I could construct the wave form that I want, but I'm seeing on oscilloscope
some oscillation of about 20us that happen randomly. I can't really say if it
is because RTAI or the oscilloscope problem. I'm investigating and when I have
a conclusion I'll post here.
Some interesting point: to test RTAI, I maid a square wave by software (a
kernel module). I saw that if the period of this wave is less than 50us,
approximately, than the system locks :D The wave continues to be executing, but
there is seems to be no more time to linux tasks, so I can't use it anymore by
serial.
Thanks everyone one more time,
Ronan.
