Hi All,

         Sometimes we add new device driver or modify present files.

However the system will stuck at "Starting kernel" when we boot board.

How do we check or debug this situation?

Some sample log as below:

==================================

so, make sure you are building the images for i.MX6Q SabreSD board.

What files you change or add? Basically, the DDR working proper and debug Uart setting correct, the kernel should be boot up and the debug message output from the debug uart .
