Hi,
I am trying to get my PCTV DVB-S2 stick running on my TP-Link
TL-WR1043ND that runs OpenWrt (Attitude Adjustment Beta, Kernel
3.3.8). I have cross-compiled the corresponding kernel modules and
deployed them on the router. I have also deployed the firmware on the
device.
After loading the corresponding modules the /dev/dvb/... devices show
up and the dmesg output seems to be fine. Then I tried to test the
device using szap and a channels.conf file. Unfortunately, the device
cannot tune to most of the transponders except of two. Both are
located in the vertical high band of the Astra 19E. For all other
transponders I do not get a lock of the frontend.
Tuning works fine on my PC using kernel verions 3.2 and 3.5 (the ones
that ship with Ubuntu) and using the same channels.conf file and
stick. So I conclude that both the stick, the satellite dish and the
channels.conf is working. I've also tested it on the router board with
an external powered USB Hub (I though that maybe the power of the
router's USB port wasn't good enough).
Now I have no further ideas. Before I start to debug the C code and
try to figure out the difference between the PC and the router - Are
there any known issues with this driver? Does it work on MIPS and
different endianess?
Best regards,
Ingo

No idea if it works or not any other than AMD64 (and i386). I use AMD64
Kernel on my computer and I cannot test easily any other arch's as I
don't have suitable hardware. i386 is so common which means bug reports
are got very quickly and fixed.
Generally speaking I am a little bit surprised these drivers seems to
just work from arch to arch quite often.

Antti

Thanks for the info. Then I'll try to fix it by myself and isolate the
error by comparing the driver behavior on the PC and my router. I hope
I can provide a patch for that afterwards.
Are there any hints where I might look first. Since it only works for
very few transponders I suppose the error in the frontend.... or not?
Regards
Ingo

Your help is very much welcome!
Try to found out some difference between working and non-working muxes.
Like you supposed, the error must be somewhere at the frontend side,
which means TDA10071 or A8293 drivers. Error descriptions sounds like
em28xx driver is not involved.

I know that they are not that powerful. I don't want to dump the whole
transportstream but just a single program (~ 10 mbit/s) contained in
it. Filtering based on the PID is done in the device isn't it?

Used em28xx chip supports pid filtering but driver doesn't.
