hi,
I've been working on a project which involves real time controlling of a
process. Because the project is in its early stages, so far the objetive
is read and write from the serial port a single bit.
The reason we chose the serial port instead of the parallel port is that
we wanted to work using industrial standards.
We wrote a mini application that toggles a LED using the module called
rt_com, which is available at rtlinux's ftp.
The problem is that in 2 months we've had 6 hard drive crashes, which we
didn't have during the time we were not using rt_com. Sometime during
the execution of the application, the file system is corrupted.
In some cases, the computer works fine after the application ends and the
modules are unloaded, but if it is rebooted, boom. In the best cases, not
even fsck recovers fixes the partition, but the partition is still there.
In the worst cases, even the partitions are lost.
I wanted to get in touch with someone who has used this module with
success,
because i would really appreciate some tips.
Just for the record, the way I'm loading the module is this:
#setserial /dev/ttyS1 port none <---- because Linux's serial driver
configures during startup all the ports it can get.
#insmod rt_com
.....
is something wrong with the first command?..... Besides the application,
our computer is usually running X, with StarOffice.
my system is a pentium / 100; 40 MB RAM; debian linux 2.1r2; kernel
2.0.36;
RTLinux 1.1
thanks for any tips/comments/experiences you email back in advance,
