Hello guys ~ !

We made TX2 Custom Board just same like Dev kit.
Only difference is camera connector soc for our camera board.
Our camera board use AR0820 with MAXIM GMSL Serializer & Deserializer.

We made sensor & serdes kernel driver successfully and checked driver probing is OK with sensor / serdes initializing is OK.

canlabtx2@canlabtx2-desktop:~$ dmesg | grep ar0820

[ 10.824385] tegra-vi4 15700000.vi: subdev ar0820 2-0010 bound

MIPI CSI-2 Data format from Deserializer is Bayer RAW12 RGGB.
Resolution is 3840 x 2160, pixel clock is 840MHz and FPS is 30fps.

After that we can get raw image with v4l2-ctl commands.

canlabtx2@canlabtx2-desktop:~$ v4l2-ctl --set-fmt-video=width=3840,height=2160,pixelformat=RG12 --stream-mmap --stream-count=1 -d /dev/video0 --stream-to=test.raw

v4l2-compliance check is OK.

And other v4l2-ctl test for check fps is OK too.

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.09 fps

Everything seems ok…

But…

We can’t get image with gtsreamer.

We already checked device-tree again and gain…

We checked compatible, devnode, reg, line_length, active_h/w, embedded_metadata_height, pix_clk_hz, discontinuous_clk, cil_settletime, devname… etc all of we can check.

But we can’t catch any other mistake.

What should we do for now?

Thank you for read our topic !

hello kyubeom21camqf0,

  1. may I know which Jetpack release you’re working with?
  2. please also note that, for sensor modules that use ser/des chip;
    the SerDes pixel clock must be specified correctly to configure the SoC-camera interface correctly and avoid buffer overrun issues. you may also check SerDes Pixel Clock session to examine your device tree property settings.
  3. according to your failure messages, it seems there’s no cameras available for gstreamer.
    please also refer to Debugging Tips session for checking your sensor drivers.
    thanks
