i.Mx 6SoloX - Accessing the MU registers

Question asked by on Sep 29, 2015

I'm using the Nit6_SoloX and soon also the Freescale SABRE 6SoloX boards to work with the 6SoloX. I have read about the messaging unit (MU) in the 6SoloX reference manual (page 2715) and understand how the MU works. However, I don't know how to access the registers through my code (C++).


From what I have gathered, registers cannot be accessed through user space. Therefore, I assume that there is some kernel driver that is being applied in the Yocto BSP layer I am using (meta-fsl-arm), giving me access to the registers.


Does anyone know where I can get more information on this? I'm guessing that Freescale provides some documentation on accessing registers from user space, I just haven't found it.


Thanks for any help
