on the terminal
Quickly press a key (on the host computer
keyboard) to stop automatic booting. The
U-Boot bootloader is pre-flashed in the
on-board NAND flash memory. At system
start up, U-Boot initializes the system and
allows the user to choose an operating
system to run.
Note: The default operating system that
automatically boots is LimeOS. To select
another operating system such as MQX,
press a key within three seconds to stop
automatic booting (autoboot).

application shows how information,
advertising or other messages can be
displayed on screens in retail stores,
corporate buildings and other
public places.
To make this the auto-boot option,
type “set bootcmd run mqxboot” and
press “Enter.” Then type “save” to save
this change to the U-Boot environment
variables in the nand flash.
To change back to autoboot Linux,
replace “mqxboot” with “nandboot.”
