Aja device not detected (Kona 3 card)

[stranger2904]

Hello

Using latest git version, obtained and compiled SDK (tried 15.5.3.1 and 15.5.4.1), ultragrid compiled successfully

83:0c.0 Multimedia video controller: AJA Video Kona/Xena 2
    Subsystem: AJA Video Kona/Xena 2
    Flags: bus master, slow devsel, latency 64, IRQ 11, NUMA node 1
    Memory at fb000000 (64-bit, non-prefetchable) [size=8K]
    Memory at e0000000 (64-bit, prefetchable) [size=256M]
    Memory at fa000000 (64-bit, non-prefetchable) [size=16M]
    Capabilities: [58] PCI-X non-bridge device

Usage:
    -t aja[[:4K][:clear-routing][:channel=<ch>][:codec=<pixfmt>][:connection=<c>][:device=<idx>][:format=<fmt>][:progressive][:RGB|:YUV]|:help] -r [embedded|AESEBU|analog]
where
    4K
        Video input is 4K.
    clear-routing
        remove all existing signal paths for device
    channel
        Channel number to use (indexed from 1). Doesn't need to be set for SDI, useful for HDMI (capture and display should have different channel numbers if both used, also other than 1 if SDI1 is in use).
    connection
        Connection can be one of: Analog1, HDMI1, HDMI2, HDMI3, HDMI4, SDI1, SDI2, SDI3, SDI4, SDI5, SDI6, SDI7, SDI8
    progressive
        Video input is progressive.
    RGB|YUV
        Set SDI video input to RGB or YCbCr explicitly. If capture pixel format is set, expect the same encoding on input. You can override this setting by specifying the signal color space explicitly by this option (see https://github.com/CESNET/UltraGrid/wiki/Device-Settings#RGB_over_SDI for details).

System is ubuntu 18, aja driver is 15.5.3 Any ideas why the card is not visible in uv ?

[erichorwitz]

Have you loaded the Aja driver? the SDK does not load the driver automatically... I believe its in the compiled bin directory for the sdk. loadAja or something like that...

[MartinPulec]

As Erich said, it looks like the card either hasn't loaded driver or the driver doesn't manage the card. In the lspci output there should be otherwise lines like this:

        Kernel driver in use: ajantv2

The command is actually load_ajantv2. You can also check this instructions (which assume the use of retail drivers, however). If you wish, I'd send you instructions for SDK driver - it is not mentioned in the wiki intentionally because the guys at AJA objected that it looks like the SDK driver is required for AJA to run (instead of retail drivers).

Also there are 2 another points - firmware may need to be updated by ntv2firmwareinstaller. Second is that Kona 3 may or may not work - I think that it is no longer supported by SDK (which doesn't tell that it won't work).
