Hello All,
I have been facing an issue where the Hikey970 boot fails with source built system.img. I followed the procedure as follows:
After converting the system.img to a raw image using simg2img tool and mounting it, following is
the directory structure in the image.

The contents however do not match with the contents of the default pre-built system.img provided by 96 boards which is:

I confirmed this behavior with multiple iterations.
This source built system.img fails to boot.
Is this a bug ? Is there something missing in the Documentation which causes this?
Any suggestions/comments are welcome.
Thank you for your time,
