Please double check that the printed values are correct! You will not be able to correct any errors later! If
there is something wrong, reset the board and restart from the beginning; otherwise you can store the
parameters permanently using the saveenv command:

5.9. U-Boot Command Line Interface
The following section describes the most important commands available in U-Boot. Please note that U-Boot is
highly configurable, so not all of these commands may be available in the configuration of U-Boot installed
on your hardware, or additional commands may exist. You can use the help command to print a list of all
available commands for your configuration.
For most commands, you do not need to type in the full command name; instead it is sufficient to type a few
characters. For instance, help can be abbreviated as h.
The behaviour of some commands depends on the configuration of U-Boot and on the definition of some
variables in your U-Boot environment.
Almost all U-Boot commands expect numbers to be entered in hexadecimal input format. (Exception: for
historical reasons, the sleep command takes it's argument in decimal input format.)
Be careful not to use edit keys besides 'Backspace', as hidden characters in things like environment
variables can be very difficult to find.
5.9.1. Information Commands
5.9.1.1. bdinfo - print Board Info structure
=> help bdinfo
bdinfo - print Board Info structure
Usage:
bdinfo
=>
The bdinfo command (short: bdi) prints the information that U-Boot passes about the board such as
memory addresses and sizes, clock frequencies, MAC address, etc. This information is mainly needed to be
passed to the Linux kernel.
