Ah, yes, mb. I will edit the messages.

Are you sure you don't mean BSP which stands for Board Support Package??

As I said above, there is no usb otg functionality. If you want shell as ordinary user - install any app which allows access to shell (I'm using "Admin hands" in local shell mode) on your tv box. In this mode 'su' refuses to escalate privileges. If you want root access, you should connect using uart (see my messages above). You will get access to u-boot and android console. There you can execute 'su' and it will give you root privileges.
