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 of the configuration of
U-Boot and on the definition of some variables in your U-Boot
environment.
All U-Boot commands expect numbers to be entered in hexadecimal
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.
