it quit simple. when you write "tlinux start mymod.o" a script calls
modprobe/insmod to insert the module and search for the module in "/lib/modules/"
and the rtlinux module path. It does not have any information of the location of
your module so it fails. You have to write (system("rtlinux start <paht to
dir>/mymod.o" or copy the module to rtlinux module path and run depmod -a.
