%SECTION0{name=UBootFirstSteps}% Initial Steps

In the default configuration, U-Boot operates in an interactive mode
which provides a simple command line-oriented user interface using a
serial console on port %CONSOLE_PORT%.

In the simplest case, this means that U-Boot shows a prompt (default:
=<nop>=&gt;=) when it is ready to receive user input. You
then type a command, and press enter. U-Boot will try to run the
required action(s), and then prompt for another command.

To see a list of the available U-Boot commands, you can type
=help= (or simply =?=). This will
print a list of all commands that are available in your current
configuration. [Please note that U-Boot provides a
_lot_ of configuration options; not all options are
available for all processors and boards, and some options might be
simply not selected for your configuration.]

%INCLUDE{DULGData_%BOARD%.UBootHelp}%

With the command =help &lt;command&gt;=
you can get additional information about most commands:

%INCLUDE{DULGData_%BOARD%.UBootHelpLong}%

Most commands can be abbreviated as long as the string remains
unambiguous (and notice how you can ask for help for more than one command at a time):
