So it looks like I simply get no acccess to mcbsp1 at all.

Hmmm, this is quite unexpected. Can you access to mcbsp2 or 3 registers, or only the mcbsp1 registers a= re not=20 accessible? One thing that I have noticed is that the McBSP1 (and 3) is under the D= SP=20 Public Peripherals, while McBSP2 is under MPU Public Peripherals (in=20 OMAP1510). I have to check it further what this actually means... > > Thanks, > Janusz --=20 P=E9ter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
