Thank you for your replay.
i have completed the NXP imx6Q android version compilation.
and then i find out the output of compilation, such as kernel U-boot and root-filesystem. but i have another question for QEMU tools, did you know the NXP imx series (android) can be booted by QEMU?
other question
The NXP imx6 series only has imx6Q and imx6D or could their plus version support Android systems? Is that right?
Actually, i have updated the QEMU version to 7.2 (latest 8.2) seems not support the imx6Q and imx6D (cortex a9), which only support imx6u.
