boot stop at "starting kernel..."

hello.

      on my iMX6ULL board, system boot stops at "starting kernel...". However, if enter uboot cmd, and run the "boot" command, we can successfully boot into kernel, what's the reason of this phenomenon? 

 

system boot log:

enter uboot cmdline, and running boot command log:
