Hello,

I loaded the module and this is the result from my dmesg.log file. I have tried to strip out things that are irrelevant!

i2c-adapter i2c-0: nForce2 SMBus adapter at 0x1c00

saa7130[0]: registered device video0 [v4l2]
saa7130[0]: registered device vbi0

So it finds it and attaches it to video0 from the looks of this log. I am assuming that the SAA is an analog tuner, or maybe a composite video input? How would I go about testing to see if this driver is interacting correctly with my card?

Regards,
Jack.

However, I am about to embark on an Embedded Systems Engineering degree and I thought that maybe, developing a device driver for this card would be a good start? Now I have found that this card incorporates the SAA7130, TDA10048 and TDA18271.

Hi Jack,

you have some new combinations here.

To load the saa7134 with i2c_scan=1 could be a start.

"modinfo saa7134"

Cheers,
Hermann
