Hi Michael,
Thank you for your email. I used RTLinux 2.2. Now the problem was solved
by changing the design, namely do the huge calculation in the user side
and send the result (huge blocks of data) to the RTLinux. Currently, I
updated to RTLinux 3.0.

Hi
Is it possible to read a rtl fifo from user space as a normal user (not
as root user)? If so, how?
Thanks.

I think this works too:
typecast to int to get the integer part, then multiply the rest with,
say, 1000, to get the three digits after the point, can do this repeatedly
to get higher precision.

Hi Olaf,
I do not understand why you destory the fifo immediately after you install
a handler for it in init_module ? I guess that is might be the problem.

different base address could not work correctly. Why this
happens and how could I have three shared memory segments for each
process?
Any hints is highly appreciated.

their center-lines, with each line contains a list of points that it

(1000 Hz) task in linux instead of RTLinux is because this task need to
use lots of graphics, big memory (60M) for object modeling, etc which are
cubersome to do in RTLinux.
Thanks in advance.

Hi David,
I tried with append "mem=256m" in lilo.conf, as also suggested earlier by
Tomasz. Not rtlinux can see all of the mormory, 256M. Thank you very much.

Hello everybody,
I think I find one bug of rtlinux-2.0. I have RAM 256M, and when boot from
NT 4.0 or Linux, both OS see 256M available. but when booting with
rtlinux, only 126M memory available, half of the real value. My memory
use two 128M.
With regards.

Hello,
Maybe my question is stupid, wish you could forgive me as a beginner.
Where could I find the output of rtl_printf(" running time %d\n", runtme)?
If one can see the value of some variables during a code executing, it is
helpful for understanding how the code behavies.
Thanks.

My first compilation of real time linux did not select the SCSI low
