[linux-dvb] Re: dvb-kernel AirStar (SkyStar2) question

I am trying to make an AirStar DVB-T PCI (REV: 1.0) card working.
This card has the MT352 chip in the frontend.

Yesterday I got the CVS snapshot of dvb-kernel and built the build-2.4 directory. Then I tried to do:

# insmod ./dvb-core.o
# insmod ./mt352.o
# insmod ./skystar2.o

and after this, dmesg reports the follow:

# dmesg
PCI: Guessed IRQ 11 for device 00:0c.0
PCI: Sharing IRQ 11 with 00:0f.0
skystar2.c: FlexCopIIB(rev.195) chip found
skystar2.c: the chip has 38 hardware filters
DVB: registering new adapter (Technisat SkyStar2 driver).
mt352_read_register: readreg error (ret == -121)

As you can see in the last line there is an error.
Looks like there is some problem with i2c.

Am I missing something? Any suggestion?


Hi Antonio,

it's most likely that the Airstar uses a different i2c adress. If you
have access to a windows box and a diassembler then you can take a look
at the driver codes to find out the adress. Another option would be to
try all configurations possible for the mt352 (shoudn't be more than 4,
I guess).

Good luck,
