imx8m EVK - Flashing Android 12 failure

[marekb]

Hello,

I'm trying to compile Androind 12 for IMX8M EVK. I followed official NXP documentation and build went fine. When trying to flash image to emmc I'm getting following when run:

`sudo ./uuu_imx_android_flash.sh -f imx8mq -a -e -u trusty-dual`

``` 

This script is validated with uuu 1.4.182 version, it is recommended to align with this version.
dual bootloader is supported
dtbo is supported
dual slot is supported
dynamic parttition is supported
vendor_boot parttition is supported

It seems it cannot flash super.img. Any ideas what can be wrong please? Thanks.

Have you missed product.img, if missed please add it and then try

UPDATE: Seems issue is caused by new uuu utility. With 1.4.182 it seems it's flashing.

I was able to flash image properly with older uuu as mentioned above. But I cannot see any output on hdmi. When flashed binaries downloaded from NXP hdmi output works. Flash command is same for both. Any idea what can cause that? Maybe dtb is different or? Thanks.

Have you use the proper command for boot up:

Just found out I need to wait some time until android logo appear. Thanks.

OK, good news it works.
