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



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

The mt352 frontend still crash if i load them for an aver dvb-t 771

Are they still under work?
Sorry that this got so delayed, but would you be interrested in testing the attached patch for the mt352 frontend, and see if that's what's needed
to get in back in workable state?
No thing, im full of patience, since you all do a well great job.
I just want to inform if i realize something bad. Never think
about blaming someone for that. On every crash the things are
getting better later.

I will check this today evening and feedback you.

Anyway, thanks for your work.
No problem, any chance this worked out for you?
