Thank you @igorpadykov for the reply,

But, I need how to load and port HDMI TX and RX firmware ( hdmitxfw.bin & hdmirxfw.bin ) in uboot as well as kernel in Android 9 Automotive with IMX8QM which is don't have any lvds connector and we have only hdmi connection.

Is it possible please provide the hdmi porting guide in Android imx8qm.

And also MEK board ram size is : 6 GB but custom board ram size is 2 GB.

#define IMX_HDMI_FIRMWARE_LOAD_ADDR (CONFIG_SYS_SDRAM_BASE + SZ_64M)

Do I needs to configure the IMX_HDMI_FIRMWARE_LOAD_ADDR for custom board ?
