Hi joanxie,

I downloaded android_p9.0.0_2.1.1-auto-ga_image_8qmek.tar.gz from the official website to the imx8QM MEK board,But can not see display on HDMI-TX. It is ok base on automotive-10.0.0_2.4.0_image_8qmek2.tar.gz
Can you tell us the patch？

Please tell us which stable baseline version are we fit to use.The main feature of our IVI mainboard is A2B audio system，GPS + IMU，nanoSIM+4G/5G module，DES CAMERA，USB CarPlay，GBE，WIFI-BT，HD Radio，STEERING WHEEL，HDMI，SPDIF，CANFD/CAN
