Thanks Andreas, you're right.

Now I have resolved this issue: I need set the value to %rambar1
register in the head.S file.
This register is the configure register for SRAM. Although I not use
SRAM memory, but it
seems I need configure this register, otherwise I will meet the issue
before.

I'm not sure why this fix will affect run time loader. I guess the
toolchain may do some registers' check.

Best Regards,
Lanttor
