Driver v120617 not working under Ubuntu 12.04

[chrism0dwk]

Dear All,

I have just upgraded by HTPC to Ubuntu 12.04 (kernel 3.2.0). After the upgrade, I downloaded version 120617 of the TBS driver and followed the instructions (copy the firmware to /lib/firmware, make, make install as in the README file). However, it seems that my 6280 is not recognised: after a reboot, there is nothing mentioned about the card in dmesg, and the kernel module is not loaded (ie cx23885). If I load the cx23885 module by hand, then dmesg indicates that it is loaded, but again no mention of the card (and my HTPC software doesn't work).

The card is present on the pci bus: > lspci -v
02:00.0 Multimedia controller: Philips Semiconductors SAA7160 (rev 03)
Subsystem: Device 6280:0011
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at f9f00000 (64-bit, non-prefetchable) [size=1M]
Capabilities: <access denied>


I reverted to my previous version of the driver software, 120412, which works fine. Is this a bug, or am I missing something? I am very happy to provide more debug information if requested.

Regards,

Chris

Hi chrism0dwk

Would you mind having a look at this topic.

Maybe this can help you.

Kind Regards

Hi Steven,

Unfortunately following the instructions in the post does not solve the issue. The cx23885 module is not loaded on reboot, and manual loading again does not detect the card.

I notice that TBS has changed the "linux-tbs-drivers" directory to "linux-tbs-sources" which makes me wonder whether something has been left out of the build configuration...

This card based on SAA7160ET bridge, no CX23855.
So all ok, saa716x modules loaded

[chrism0dwk]

Well, therein lies the rub: the saa716x modules are /not/ loaded. Interestingly, they are also not installed into the /lib/modules/`uname -r` tree either. That is why I am wondering if they got missed out of the build config.

NB. If the 6280 card does not use the CX23855 driver, then the README file in the current driver release is definitely wrong.

see README_TBS62XY - no any refrences to cx23885.

Heh, interesting. The .zip download appears to have changed since I last downloaded it (tbs-linux-drivers_v120617.zip as opposed to tbs-linux-sources_v120617.zip which came down previously). This archive includes the README file you mention above.

I'll give it a go as soon as I can, though I am about to pack my belongings to ship to the other side of the world...may be 3 months.
