ADV7180 driver for IMX6

quenreyn — Thu, 25 Apr 2019 08:12:28 GMT

Hi,

I am trying to use gstreamer with hardware acceleration from IMX core with phyflex-imx6-4 and a proprietary board.

The camera I use is the KPC-HD30MB.

I built yocto yogurt distribution with the following meta:

meta-poky
meta-openelbedded/meta-oe
meta-openelbedded/meta-networking
meta-openelbedded/meta-multimedia
meta-gstreamer1.0
meta-freescale
meta-phytec
meta-yogurt
meta-rauc

I used CORE_IMAGE_EXTRA_INSTALL to add some packages into the distribution:

imx-codec
imx-vpu
imx-vpuwrap
libimxvpuapi
imx-parser
gstreamer1.0 + libav, bad, good, ugly, base, imx

Do I need firmware-imx or imx-gst1.0-plugin (which I have not managed to install) ?

adv7180 driver is well probed and the I2C address is correctly detected.
ipu2_csi1 is used

There is an extract of my dts:
    adv7180@20 {
       compatible = "adv,adv7180";
       reg = <0x20>;
       pinctrl-names = "default";
       pinctrl-0 = <&pinctrl_ipu2_2>;
       clocks = <&clks IMX6QDL_CLK_CKO>;
       clock-names = "csi_mclk";
       ipu_id = <1>;
       csi_id = <1>;
       mclk = <24000000>;
       mclk_source = <0>;
       cvbs = <1>;
   };
pinctrl_ipu2_2: ipu2grp-2 { /* IPU2_CSI1: 8-bit input */
   fsl,pins = <

   MX6QDL_PAD_EIM_A22__IPU2_CSI1_DATA17   0x80000000

   MX6QDL_PAD_EIM_DA12__IPU2_CSI1_VSYNC   0x80000000
   >;
};

The gstreamer pipeline works with a test video with the following command:
> gst-launch-1.0 -v videotestsrc ! video/x-raw ! x264enc ! filesink location=/home/root/capture.mkv

When using "imxv4l2videosrc" with device=/dev/video7 instead of "videotestsrc", the pipeline crashes:
> gst-launch-1.0 -v imxv4l2videosrc device=/dev/video7 num-buffers=1 ! video/x-raw ! x264enc ! filesink location=/home/root/pal_capture.mkv

It also crashes with "v4l2src" source:

Do you know which driver I need to use besides the adv7180 driver ?

Do you know any test I can run to verify /dev/video7 is the right source (I am not sure of anything anymore) ?

Is there a way to set the video channels ipu2_csi1_xxx easily ?

Thank you in advance,

Quentin.

Hi Quentin

"imxv4l2videosrc" plugin is part of gstreamer-imx plugins,

issue may be posted on Issues · Freescale/gstreamer-imx · GitHub

For "v4l2src" one can try nxp linux from source.codeaurora.org/external/imx/linux-imx repository

linux-imx - i.MX Linux kernel

and follow sect.7.3.9 Recording the TV-in source attached Linux Guide.
