Hi,All
Now I want to use imxotp,but before using it,I should enter into the uboot cmd UI,and I dont know how to enter it. Some info told me,when I loaded the uboot via the mfg tool and then uboot cmd UI would show up after the uart was started automatically.
But all of these didnt happen. So I want to know the steps how to do after load uboot in detail. and more importantly, what I used is our customized board. So please help me!

By u-boot cmd UI you mean the u-boot command prompt / shell?
Do you see u-boot traces while the board is booting, like:
U-Boot 2011.12 (Jan 16 2015 - 09:22:38)
......
Hit any key to stop autoboot: 0

Hit any key to stop autoboot: 0 <-- Do you see it counting at this stage ( I think default is 3 secs), or not?
If yes, you should be able to hit a key at this stage and autoboot is interrupted and you *should* get the u-boot shell.
If it's not counting then this wait delay must be disabled, and you can enable it and rebuild u-boot and upload it.
Also check this link, for modifying u-boot from linux. (if your distro does not have it built already..)
