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 are not accessible? One thing that I have noticed is that the McBSP1 (and 3) is under the DSP Public Peripherals, while McBSP2 is under MPU Public Peripherals (in OMAP1510). I have to check it further what this actually means... > > Thanks, > Janusz -- Péter -- To unsubscribe from this list: send the line "unsubscribe alsa-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
