Hi All,

I'm using imx6 Dual Lite with 1G and take Android6.0 as my OS system.

I'm having an issue with repeating starting kernel.

After I burned my image in, I repower the machine and the debug log shows as below.

shivanipatel‌ Thanks for your reply.

I have found the problem.

It's because of DTS settings.

Hi, tsung li wang

Please try these prebuilt images of i.MX6DL/6Q/6QP in your board. As I am able to boot the board using these images.

Regards,

Shivani Patel

Possibly the kernel fails because of some memory failure.
Please try to perform memory test:
https://community.nxp.com/docs/DOC-105652

Also please try to remove as many devices from the configuration as possible.
There is a chance that some driver is wrong.

Have a great day,
Victor
