Creating custom Android 9 image for EDM1-IMX6Q

Ketki — Wed, 30 Sep 2020 10:55:27 GMT

I downloaded the code from git and compiled it with "cook -j4" without any errors.
After that I used the command gen_virtual_images which created a 3.6GB test.img file .
I moved it to a bootable SDCard and on power on it reboots in a loop. I need to know more about gen_virtual_images as there is no documentation about the same . When I use this u-boot.imx is not created. Could that be the reason behind the problem as all other files mentioned for EDM1-IMX6Q are generated .

I get the following message :

I recommend you that you contact the board supplier, since the Android BSP can be build in different ways, you can review the method, that we use in NXP boards, and the documentation on how to boot a NXP board with an Android Image, we use our tool named UUU,

Here you can find the details

Thank You for the reply.

I am not getting any great help from my supplier so I thought of raising my queries in the community.
It would be of great help if you could resolve my query.
Can you please verify that the file u-boot.imx not generated after compiling Android 9.0 could be the issue ?

Also I am using the board EDM1-IMX6Q-10-R20-E16-9377 with Fairy and Android version tn-p9.0.0_2.2.0-ga .
Is this Android version compatible with EDM1-IMX6Q ?
