From L5.4 BSP, the iMX8QM HDMI RX feature is removed from BSP, but it is added back in L5.10.52 2.1.0 BSP. The followed is the detail steps to use HDMI RX.

 

  1. We need enable the followed kernel config to make hdmirx driver work:

    CONFIG_IMX8_MEDIA_DEVICE=y
    CONFIG_MHDP_HDMIRX=y

  1. apply the attached kernel patch.
  2. put hdmi firmware “hdmirxfw.bin” and “hdmitxfw.bin” to SD card’s FAT partition
  3. test command:

    gst-launch-1.0 v4l2src device=/dev/video2 ! autovideosink

    run loadhdprx
    hdprx load 0x9c800000
    setenv fdt_file imx8qm-mek-hdmi-rx.dtb
