su root
This will prompt you for the root password. Enter the root password. From this point on, this window will now be used as your root account. Avoid using this window unless you are either inserting or removing modules.
WARNING: execution of this and most of the following commands may open up some security holes. However, most real time control systems have no business being used in a multi-user networking environment. You have been warned.
You need to make sure that you have read/write permissions to the real time FIFOs. So, as root, and if you haven't done so already, type:
chmod 666 /dev/rtf?
Similarly, you need to set similar permissions to /dev/mbuff so that you can use shared memory between real time and non-real time tasks:
chmod 666 /dev/mbuff
Finally, you can load your module. From the ~rtic-*.*.*/bin directory. type:
./ rtlinux start rtic
This command will load all of the Real Time Linux modules and will also insert the user module ``rtic.o''. Your code is now ready to run.
