UBootPowerOn < DULG

%SECTION0{name=UBootPowerOn}% The First Power-On

%H% Note: If you bought your %BOARDNAME% board with U-Boot already installed,
you can skip this section since the manufacturer probably has already
performed these steps.

Connect the port labeled %CONSOLE_PORT% on your %BOARDNAME% board to the
designated serial port of your host, start the terminal program, and
connect the power supply of your %BOARDNAME% board. You should see
messages like this:


%INCLUDE{DULGData_%BOARD%.UBootBoot}%

You can interrupt the "Count-Down" by pressing any key. If you don't
you will probably see some (harmless) error messages because the
system has not been initialized yet.

%IF{ "%HAVE_WARN_BAD_CRC%" eq "true"}%
%INCLUDE{WarningBadCRC}%
%ENDIF%

At first you have to enter the serial number and the ethernet address
of your board. Pay special attention here since these parameters are
write protected and cannot be changed once saved (usually this is
done by the manufacturer of the board). To enter the data you have to
use the U-Boot command =setenv=, followed by the
variable name and the data, all separated by white space (blank
and/or TAB characters). Use the variable name
=serial#= for the board ID and/or serial number, and
=ethaddr= for the ethernet address, for instance:

%INCLUDE{DULGData_%BOARD%.UBootSetSerial}%

Use the =printenv= command to verify that you have
entered the correct values:


%INCLUDE{DULGData_%BOARD%.UBootPrintenvBoardID}%

Please double check that the printed values are correct! You will not be
able to correct any errors later! If there is something wrong,
reset the board and restart from the beginning; otherwise you can
store the parameters permanently using the =saveenv=
command:

%INCLUDE{DULGData_%BOARD%.UBootSaveenv}%
