u-boot is completely "locked down". You'll need to obtain an unlock code from TAC just to delete stuff.

HI Leo

Thanks for your response!
As your meaning,we cannot enter to the u-boot mode,right? But,i have a issue that is,we can hit the "ESC" to interrupt the boot process,if we do this,what mode will we enter?

Without TAC unlocking code (one-time-use only), you can easily get into u-boot, however, and limited to non-destructive commands.

get it ,but how to get into the u-boot we can,by enter the ESC when ap boot process?
