Please take small steps.

First of all, try the examples, such as mini.c and rtai_example.c. Get them to 
compile and load first. Change your hardware so that the examples load. When 
that works, you may start modifying in _small_ steps until you are confident 
enough to start your own projects.

Apart from attaching the output of
ethercat slaves
also attach output
dmesg
(and please not everything, only the important parts!!)

Mit freundlichem Gruß
