REVIEW COPY
Initial Steps
In the default configuration, U-Boot operates in an interactive mode providing a simple
command line-oriented user interface using the serial console on port
In this CLI mode, U-Boot shows a prompt (ATCA-C110>) when it is ready to receive the user
input. You can type a command from the command line prompt, and press enter. U-Boot tries
to run the required action(s), and then prompt for another command.
To see a list of the available U-Boot commands, type help, or type "?". This command prints a
list of all commands that are available in the current configuration. For example:
