Hey antti, list,
whilst trying to help some Asus U3100+ users with the recent patches I
ran into an issue. For some strange reason his chip_id was 0xff. I'd
hope this is somehow supplied by the firmware. I think I had the exact
same issue until I used Antti's latest firmware for the AF9035.
Having said that, I know antti currently hosts the latest firmware for
the af9035, but there seem to be several out in the wild and people
googling for the firmware tend to find the really old one.
Yes, it is the firmware. AF9035/AF9033 firmware is aware of used tuner
and there is some logic inside firmware for each tuner, like
calculating signal strength and handling of tuner I2C bus. Same
applies for AF9015/AF9013 too where this has caused some notable
problems - I have asked few times if someone could reverse and fix
that fw to behave better.
Ok, then I'll await said test results with latest firmware.
I'm pretty certain that Afa-tech, IT-tech etc won't allow the firmware
to live in the kernel, or simply refuse to answer shuch a plead? They
could be persuaded by the maintainer to at least have it live in
http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git or
if that fails, have it pulled by Documentation/dvb/get_dvb_firmware?
(Btw, why is it get_dvb_firmware? I didn't find a generic script or
other devices that did the same).
Feel free to try. I tried it ages back in 2009 but failed.
i'll doubt anything has changed here :S
Someone should make some study of these firmwares and list what are
differences, supported tuners etc. That was discussed at the time
af9035 was merged to the Kernel... As rule of thumb test first newest
firmware.
Currently there is no 100% automated script to dump those firmwares
from the binary. AF9035 driver seems to contain multiple firmwares.
Maybe making script that finds and dumps all firmwares found from
binary could be handy.
Maybe as an alternative, also have the firmwares linked/uploaded to
http://linuxtv.org/downloads/firmware/ ?
I'll update the af9035 wikipage to link to antti's firmware for now.
Good!
and done.
those older firmwares for the af9035 are only there for archive
purpouse? Or are their known cases where older firmware is needed? At
this moment, it seems that the oldest one (11.5.9) brakes things.
