Hi

I'm not sure i'm doing it right. I'm using a  2.6.8-1 kernel and
linuxtv-dvb-1.1.1 with PCTV SAT CI card.

Here is what i'm loading :
modprobe videodev
modprobe bttv card=113 i2c_hw=1
modprobe dvb-core dvbdev_debug=1 dvb_frontend_debug=1
modprobe v4l1-compat debug=1
modprobe dst dst_verbose=1 dst_debug=1
modprobe dvb-bt8xx debug=1

dmesg is :

	something wrong here. dst will not read card type from CARD. maybe a char 
major problem ?

  

dvb_bt8xx: enumerating available bttv cards...
dvb_bt8xx: identified card0 as DST DVB-S

write_dst: write_dst error (err == -5, len == 0x08, b0 == 0x00)
    

	Yes, will not write to card ..

  

dst_check_ci: write not successful, maybe no card?
    

	maybe a char major problem

  

DVB: register adapter0/demux0 @ minor: 4 (0x04)
DVB: register adapter0/dvr0 @ minor: 5 (0x05)
DVB: register adapter0/net0 @ minor: 7 (0x07)

The ci is not very important. But when i try to launch the scan dvb apps
it says :

scanning /usr/local/addons/dvb-s/Astra-19.2E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:1882: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 19 No
such device

    

	dst could not find what frontend it is

  

The dst module is the frontend isn't it ? It's loaded :
lsmod :

dvb_bt8xx               6404  0

videodev                8000  1 bttv

Is this a char major pb or am I simply doing it badly ?

    

	Looks like so .. If not the recent changes in the CVS might've broken the 
driver. The previous versions, before the 2.6.8 stuff work fine though.

Hi Manu,

Hmm. I see. What do you advice ? come back to a 2.4 kernel ? I've already managed to set up TwinHan clone uder it ( a Hercules SmartTV sat). Quite tricky, but it worked fine.
I'm using a home made linux box (lfs). I'm planning to set up a dedicate DVB linux box for MythTV what is already ready ( distro is < 200 mb and stands on a USB KEY). The next step is to get a fully  compatible TwinHan clone for evreyone.

Thanks for help. cheers

Pierre
