%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>=>=) 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 <command>= 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): %INCLUDE{DULGData_%BOARD%.UBootHelpAbbrev}%
