The story is: for sama5d3x with Cortex-A5 core, if not so, when copying code snippet to the internal SRAM, then jump to run this code, but fail to run.
So, refer to other code(such as omap4), do such change. I also test it on at91sam9 with 926ej-s core.
As what you said, I am digging it. Thank you very much.
