Re: dvb-s2 card "TeVii S472" (cx23885)

[Hendrik Oenings <debian@oenings.de>]

Hi together,

I tried to recompile with the newest media_tree, so I just copied your
modifications to the new media_tree. (I also refetched the media_build.)
It wasn't very helpful, but I've seen that there is a kernel
error message (which was there before too, but I hadn't seen it because
I worked on X).

$ su -c "modprobe cx23885"
modprobe: ERROR: could not insert 'cx23885': Exec format error
$ dmesg
...
[XXXXXX.XXXXXX] frame_vector: exports duplicate symbol
frame_vector_create (owned by kernel)

I've looked up the reason for the re-export and I have seen that
frame_vector was built as an module, but is compiled into the kernel.

Changing this in the ./media/v4l/.config from m to y worked, so I can
now load the module.

The kernel message is gone away, but there is another problem now,
dmesg says and w_scan doesn't work either:

[XXX] m88ds3103 7-0068: found a 'Montage Technology M88DS3103' in cold
state

[XXX] m88ds3103 7-0068: downloading firmware from file
'dvb-demod-m88ds3103.fw'

[XXX] m88ds3103 7-0068: firmware did not run

I've copied the firmware as suggested to /lib/firmware.

Regards,
Hendrik
