[linux-dvb] Re: [PATCHES] Frontend kernel i2c conversion.

[Andreas Büsching <crunchy@tzi.de>]

Hi,

I just got my new DVB-T card (AverMedia 771) yesterday and ran into the 
same problem as Andreas. When I tried to load the mt352 module it 
crashed on mt352.c:827 (I guess; the line looks like 
BUG_ON(!state->dvb)). So I applied your patch, which definitly changed 
something in the behaviour. I can load the module and get the debug 
message 'dvbfe_mt352: Setup for Avermedia 771.'. But that seems to be 
everything. As I'm new to this stuff I'm not sure how to check that the 
card is working correctly now, but I tried the following:

- downloaded the dvb-apps from CVS
- ran dvb-apps/util/scan/dvbscan ./dvb-t/de-Bremen

what results in:

scanning dvb-t/de-Bremen
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:1957: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No 
such file or directory

According to this message the mt352 is not running correctly

Also I'm not sure if I did everything else correct with the bt* driver 
stuff. Currently I load the following modules:

# DVB-T AverMedia 771
dvb-core
bttv i2c_hw=1 card=0x68
bt878
dvb-bt8xx
i2c-nforce2
i2c-algo-pcf

I added the i2c modules because there are some syslog messages looking 
like errors. These messages appear while loading the mt352 module:

i2c_adapter i2c-0: sendbytes: error - bailout.
i2c_adapter i2c-1: sendbytes: error - bailout.
i2c_adapter i2c-2: sendbytes: error - bailout.

I hope this helps to find the bug! If you need any more information just 
ask.

appreciating any help
