Subject: saa7146 firmware upload time?
Date: Sun, 2 May 2010 19:13:08 +0100 (BST) [thread overview]
Message-ID: <alpine.DEB.2.00.1005021904150.4041@alice> (raw)
Hi
My "WinTV NOVA-t" PCI card is recognized by the saa7146 driver (ubuntu
9.10 2.6.31-21-generic kernel), but I don't have a /dev/video0. At some
point I noticed messages in syslog about missing firmware (below), and
rectified that by fetching the firmware and dropping it in /lib/firmware.
However, there's a big gap (over an hour and a half) between boot and the
time when the driver complains about the firmware:
May 2 16:00:28 alice kernel: [ 58.447825] saa7146: register extension 'budget_ci dvb'.
May 2 16:00:28 alice kernel: [ 58.449357] budget_ci dvb 0000:05:01.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

May 2 17:40:39 alice kernel: [ 6057.449458] tda1004x: no firmware upload (timeout or file not found?)
May 2 17:40:39 alice kernel: [ 6057.449461] tda1004x: firmware upload failed
May 2 17:40:39 alice firmware.sh[4365]: Cannot find firmware file 'dvb-fe-tda10045.fw'
I don't know anything about the kernel but looking at the source seemed to
suggest the driver looks for the firmware at modprobe time, but rmmod
followed by modprobe doesn't give me any messages about firmware (nor does
a reboot). What should I do to trigger this firmware upload process
again?
Thanks
John
