Subject: [resend] XC5000 firmware for Pinnacle 800i
Date: Mon, 26 May 2008 13:09:44 -0700 [thread overview]
Message-ID: <483B1908.7000609@nvr.com> (raw)
Recently I installed mythtv on fedora core 8 using yum for most of the
packages and v4l for the dvb support (v4l-dvb-fee5c2458384.tar.gz). I
have the Pinnacle 800i, and the drivers for the cx88 installed
correctly, and the firmware from http://www.steventoth.net/linux/xc5000
always loaded. The problem was that nothing could detect any atsc
reception, including myth setup and dvb-atsc-tools-1.0.7. After
eliminating the antenna, cable, configuration, and rebooting many times,
I finally humbled myself and booted up XP and installed the drivers that
came with the card. Atsc reception worked.
So then going back to linux, I find that myth setup detected all the
channels, and everything works!
Keep in mind that I have little experience with myth or v4l or the
drivers, so take this with a grain of salt... in my experience
(elsewhere) this suggests a couple of explanations:
* the windows drivers installed the firmware correctly (making it
work). At the very least, it had some positive influence.
* the board logic retains a firmware installation and is smart
enough to detect an invalid firmware update (which makes it work under
linux in spite of bad firmware being loaded or loaded incorrectly).
* If the firmware is bad, this could be the shell script (which
extracts the firmware by dd'ing it out of the middle of a .sys file)
doesn't get quite the right bytes). This seems unlikely since it
probably worked for the author.
* It could be that the firmware is the wrong version for the 800i
(the readme that comes with the firmware says that it is the official
Haupauge WHQL driver).
* It also could be possible that the linux firmare is correct, but
that the windows driver did some other operation to the board (like
updating other firmware), that then allows the linux driver firmware
load to work correctly.
It would be nice is one of you could shed some light on this, although
for me this problem is solved. Perhaps this may help others get past the
same very irritating brick wall with the 800i.
