Yes, that's what I wrote above. The base address register mapping the mcBsp at a given address would be described in the detailed spec of the SoC, the one with all registers. > it is interesting to > note that in the UART case I have no suce problem. The UART's and mcBSP are > quite similiar. Indeed, but this does not mean they are mapped the same way. You can only tell by looking at the detailed register map of the SoC. > Regards, > > Ran Amicalement, -- Albert.
