I download android-11.0.0_2.0.0_image_8mmevk.tar.gz and burn eMMC by:

uuu_imx_android_flash.bat -f imx8mm -a -e -d mipi-panel -c 28

 

The android bootd up successfully and message comes from usb-uart, but HDMI does not have output. The monitor shows no signal. But if I download linux kernel, HDMI has output.

 

I also tried android-10.0.0_2.6.0_image_8mmevk.tar.gz, still failed at HDMI.

So anybody can give some clues?

Hello,

   Have You used recommendations of the start guide how to transfer image and configure
U-Boot environment variables for the HDMI?
