I spent a while debugging this, so figured I'd store this to the mailing
[SOLVED] Mythtv Mythbuntu DVB firmware problem with dvb-fe-tda10046.fw
list for others' reference.
If you have one of these devices: (there are various revisions)
01:05.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
01:06.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
If you initially have a corrupt, outdated or broken dvb-fe-tda10046.fw
firmware file, you will see messages like this in the syslog, or dmesg -
please rename the firmware file to dvb-fe-tda10046.fw
found firmware revision 0 -- invalid
no firmware upload (timeout or file not found?)
The fix is to first fetch the correct firmware.
This remains a problem since the get_dvb_firmware can no longer access the
original page to download the firmware file TT_PCI_2.19h_28_11_2006.zip. At
the time of writing (2012-06-25) this file is available from a few other
places - google it. Then place this file in the same directory as the
If you're running Ubuntu or Mythbuntu, you can also:
apt-get install linux-firmware-nonfree
To get a good firmware. It needs to be copied into /lib/firmware
You will then *NEED* to cold boot.
Until you reboot each load of the firmware will result in the above
mentioned errors, and channel scanning, tuning, live tv, etc. will fail.
After a reboot it all works perfectly.
The above problems could also have been caused because I also have a another
different revision of the card which wants dvb-fe-tda10045.fw too. So I
needed both firmwares, one for each card.
