Have a look at el1262.m for a good example of using oversampling; even
the output vector and PDO's are calculated dynamically based on the
oversampling factor. For example, to turn on oversampling rate 4,
choose:

You need to tell the master the slave's layout using these functions

In this case the master can start even without the bus being connected.

First things first: when you are running RT proggies, you need a stable

reference to that module. Only in the init script. So, rtai_math
module is required?
I tried without the module and all the stuff appear to run ok.

You will have to change this line by hand every time after generating code. I
could not automate that. Maybe you make yourself a little script with a sed
command in it to do that. Otherwise, this is a well used setup by us.
Thanks

Thanks.

the modules where it seems fit. You probably have a
build system separate from your target system. On your target you will have to
figure out how to get the etherlab kernel object where modprobe can find it.
