HVR2200 Corrupt Image?

We’ve had a handful of reports cropping up related to HVR2200 model#89619 cards. With Ubuntu 12.04.1 the driver would attempt to load firmware from file NXP7164-2010-03-10.1.fw length 4019072 as defined in the saa7164-fw.c driver source.

(Hint: it’s not really an Ubuntu error)

Sep 13 07:50:56 dell kernel: [ 83.432854] saa7164_downloadimage() image corrupt
Sep 13 07:50:56 dell kernel: [ 83.432868] bootloader d/l has failed
Sep 13 07:50:56 dell kernel: [ 83.433068] Failed to boot firmware, no features registered

Technically, NXP have two different revisions of the SAA7164 chip, rev2 and rev3. Up until 2010 I was loading different firmware into the chips based on a revision identifier on a per card basis.

In March 2010 I received a newer firmware build from NXP that fixed some MPEG Encoder loss of signal related issues. I tested this on both DVB-T and ATSC rev2 and 3 cards, saw that it had no obvious problems then patched the saa7164-fw.c driver to use a single firmware. To the best of my knowledge it has been working fine for over two years.

Apparently not. Apparently the NXP7164-2010-03-10.1.fw firmware fails to boot specifically on the rev 89619 DVB-T cards.

Thanks to the Hauppauge Engineer Team I was given some 89619 loaner hardware to reproduce the problem on. I was able to quickly reproduce the issue with a very recent v3.6 kernel and provide a preliminary patch to correct the problem.

Oh, you’ll also need to download and install v4l-saa7164-1.0.2-3.fw firmware into your /lib/firmware directory.

This tree http://git.kernellabs.com/?p=stoth/media_tree.git;a=shortlog;h=refs/heads/saa7164-dev contains an experimental patch to regress all saa7164 rev2 cards back to a specific rev2 firmware. It was tested with a 89619 card and the driver is loading and operating correctly.

The patch has not been regression tested against any other rev2 cards.

Update:The patch has been fully regression tested against all rev2 cards supported by the driver, the 89519 and the 89615. It’s safe to use.


One thought on “HVR2200 Corrupt Image?

  1. HVR2200 V2 kernel patch

    This patch compiled OK under kernel 3.6, but I have now done an upgrade and gone to 3.8 where it will not compile.

    I get
    In file included from /home/(user)/media_tree/drivers/media/pci/saa7164/saa7164.h:58:0,
    from /home/(user)/media_tree/drivers/media/pci/saa7164/saa7164-cards.c:27:
    include/media/videobuf-dvb.h:1:20: fatal error: dvbdev.h: No such file or directory
    compilation terminated.
    Can you advise a work around?
