Please report issues with all details, typically error codes and return 
values. "call fails" is not enough.

Although using rtdm_open() for /dev/rtp0 may work, this pseudo-device 
file should be opened using a plain open(2) call, since we want to open 
the regular linux-side endpoint for the communication.

Obviously, yes. Check IPC drivers in the "Drivers" sub-menu of the 
Xenomai configuration. You need to have CONFIG_XENO_DRIVERS_RTIPC_XDDP 
enabled.
