Wintv-1250 - EEPROM decoding - V4L DVB

Hi,
I was trying to get the WINTV HVR1250 analog interface to work. So far I kludged the cx23885-cards.c file to enable the decoding of
the eeprom.
The required offset in the eeprom is 0xC0

I did not get very for after that.

FYI the firmware suggested by development site sees wrong ... The
encoder firmware especially. I think that the following profile is required by the code.
The code requiresfirmware with these sizes (these are from the
hauppage distro.

I hope this helps.

Thanks.

Hauppauge have various revs of the 1250 and the eeprom offset can change. It looks like your model is different the the stock HVR-1250 I've seen.

- Steve

Please don't drop the mailing list off of replies. Linux wouldn't exist if we perpetuated this habit.

To answer your question, no significant differences. Analog won't work because I haven't done it. :)

The eeprom offset is the only notable difference at this point. I'll look into this, at some point.

- Steve

Steve,
Point taken about dropping the mailing list.
Thanks!
Michel

Thanks, one last question.

Look a the white Hauppauge label on the HVR-1250 tuner, its should say something like Rev NNNN.

What is your rev?

- Steve

I have rev E1D9. Below is my dmesg output after applying the same change as Michel had shown.

I have implemented this same change and found this eeprom offset works correctly on my HVR-1250 as well. Not that it really helps anything at this point. Is there a datasheet available to the public for this chipset?
