^^^^^^^^^^^^^
It can't init the (programmable) IF thus it can't tune. I don't have a pvr and
am not very familiar with v4l2 and not at all with this port, but this is a
common tuner thing. At this stage carrier frequencies and the like get set
depending on if you have PAL B/G or I, etc. If that fails it won't be able to
tune or to get an image (carrier frequencies etc). I have similar code (only
on the iic device rather than iicbb) in kbtv for tuning SAA based TV cards
(analog).
Maybe there's a device permission problem where the user may not write to the
iic device(s)? Or (but then the port/code has a problem I'd reckon) you need
to reset the bus (before start) or it doesn't have proper tda support at all.
Was reading this thread, thought at least I could point to the place where
things go wrong.
