I finally did what I should have already done before: learned about dynamic debugging, turned it on and probably got the answer from omap_msbsp_dump_reg(): all mcbsp1 register read operations returned 0xffff. So it looks like I simply get no acccess to mcbsp1 at all. Now I wonder if I can close this thread with a conclusion that mcbsp1 on opam15xx is simply not yet supported by the mainline kernel that I have based my work on. Thanks, Janusz
