%SECTION0{name=UBootCmdGroupInfo}% Information Commands

%SECTION1{name=UBootCmdBdinfo}%   bdinfo  - print Board Info structure

%INCLUDE{DULGData_%BOARD%.UBootBdinfoHelp}%

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.

%INCLUDE{DULGData_%BOARD%.UBootBdinfo}%

%SECTION1{name=UBootCmdConinfo}% coninfo - print console devices and informations

%INCLUDE{DULGData_%BOARD%.UBootConinfoHelp}%

The =coninfo= command (short:
=conin=) displays information about the available
console I/O devices.

%INCLUDE{DULGData_%BOARD%.UBootConinfo}%

The output contains the device name, flags, and the current usage.
For example, the output

<verbatim>
serial   80000003 SIO stdin stdout stderr
</verbatim>

means that the =serial= device is a system device
(flag ='S'=) which provides input (flag
='I'=) and output (flag ='O'=)
functionality and is currently assigned to the 3 standard I/O streams
=stdin=, =stdout= and
=stderr=.

%SECTION1{name=UBootCmdFlinfo}% flinfo  - print FLASH memory information

%INCLUDE{DULGData_%BOARD%.UBootFlinfoHelp}%

The command =flinfo= (short: =fli=)
can be used to get information about the available flash memory (see
<emphasis>Flash Memory Commands</emphasis> below).

%INCLUDE{DULGData_%BOARD%.UBootFlinfo}%

%SECTION1{name=UBootCmdIminfo}% iminfo  - print header information for application image

%INCLUDE{DULGData_%BOARD%.UBootIminfoHelp}%

=iminfo= (short: =imi=) is used to
print the header information for images like Linux kernels or
ramdisks. It prints (among other information) the image name, type
and size and verifies that the CRC32 checksums stored within the
image are OK.

%INCLUDE{DULGData_%BOARD%.UBootIminfo}%

%H% Like with many other commands, the exact operation of this command
can be controlled by the settings of some U-Boot environment
variables (here: the =verify= variable). See below
for details.

%SECTION1{name=UBootCmdHelp}% help    - print online help

%INCLUDE{DULGData_%BOARD%.UBootHelpHelp}%

The =help= command (short: =h= or =?=) prints online help. Without any
arguments, it prints a list of all U-Boot commands that are available
in your configuration of U-Boot. You can get detailed information for
a specific command by typing its name as argument to the =help=
command:

%INCLUDE{DULGData_%BOARD%.UBootProtectHelp}%

%IF{ "%HAVE_DTT%" eq "true"}%
%SECTION1{name=UBootCmdDtt}% dtt - digital thermometer and thermostat

The =dtt= subsystem allows access to information provided by
temperature sensors:

%INCLUDE{DULGData_%BOARD%.UBootCmdDttHelp}%

To read the current value of the sensors, the =dtt= command is used:

%INCLUDE{DULGData_%BOARD%.UBootCmdDtt}%
