Blackmagick Decklink Extreme on Ubuntu 10.04

Good time of day!

Can I get some help from Blackmagic guru here?

I'm trying to install Decklink Extreme card on Ubuntu 10.04, but there's no luck yet.

So, my lspci:

lspci | grep Blackmagic
28:00.0 PCI bridge: Blackmagic Design Device 8111 (rev 21)
29:00.0 Multimedia video controller: Blackmagic Design Device a118 (rev 0e)

I've downloaded the latest driver from BM site. Installation have passed successfully. After rebooting

lsmod | grep blackmagic
blackmagic 429221 0

But no blackmagic devices has appeared in /dev

ls /dev
audio lp0 ram9 tty12 tty41 urandom
block mapper random tty13 tty42 usbmon0
bsg mcelog rfkill tty14 tty43 usbmon1
bus mem rtc tty15 tty44 usbmon2

Blackmagic control center shows "No Blackmagic devices found" window.

I've tried other linux distros (openSUSE, Fedora), older card drivers, and even older Decklink Extreme PCI card too, but had the same results.

If somebody knows any receipts how to make Decklink work on linux, I'll be very appreciate for it.

Thank you for advance

Can you verify successful driver installation through package management? Which driver version did you install? Blackmagic DesktopVideo (I'm using 8.0) has BlackmagicFirmwareUpdater -status to check card status as well as the another function to launch the Blackmagic control panel.

Good luck!

Hi, Wen!

Thank you for your answer.

Yes, desktopvideo package is installed. I installed 8th version,

dpkg -l | grep Black
ii desktopvideo 8.0 Blackmagic Design DesktopVideo Driver and Ut

BlackmagicFirmwareUpdater status doesn't return anything.

I've tried this decklink card with windowsXP to be sure my motherboard and my decklink compatibility. It works well.

You're very welcome. I'm having my own troubles getting my Decklink card to work so I empathize. From Blackmagic's own FAQ (below), "My Blackmagic card is not working, what should I do?" they suggest a clean installation, including physically removing/inserting the video card. I found that this suggestion worked when I dual-booted my system with another version of Linux where the system detected the card (lspci and lsmod) but Blackmagic diagnostic software (BlackmagicControlPanel, BlackmagicFirewareUpdater) did not.

I am in the same situation.
The card works in Windows 7.

In Ubuntu 10.04 I get the following messages when the computer starts:(dmesg)

[ 15.450972] *** bool DeckLinkDriverClass::firmwareHasDownloaded()[1616]: Failed to initialise video output support
[ 15.451075] blackmagic: ERROR: failed to download firmware
[ 15.451087] blackmagic_driver 0000:02:00.0: PCI INT A disabled

In log messages (var/log/syslog) do you have a vmalloc error, asking to increase size, right before the errors you posted? If so, the resolution maybe to increase VM size with these steps:

1). Check your current vmalloc sizes
$ cat /proc/meminfo | grep Vmalloc

2). Increase VM size
$ sudo nano /etc/default/grub




GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=256M"

(modify the following as necessary for your grub version)
$ sudo update-grub2

4). Verify changes, by looking for the vmalloc instructions in this file
$ cat /boot/grub/grub.cfg

5). Reboot

6). Double check if your changes has had effects
$ cat /proc/meminfo | grep Vmalloc
