Hi, I am currently working on a project which is running on a PowerPC platform. In my rtdm driver, I use "rtdm_iomap_to_user" to map a few I/O memory locations to be accessed from my application. All the function calls seem to work (no error code returned). But my application fails to use these pointers to manipulate any I/O. Is there any restrictions I have to be aware in order to use those mapped I/O mem? I am new to xenomai. I would really appreciate any help to this.
Best Regards, Haobo Zhang
