5.8. The First Power-On

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

Connect the port labeled UART1 on your canyonlands board to the designated serial port of your host, start the terminal program, and connect the power supply of your canyonlands board. You should see messages like this:

=> reset

U-Boot 2009.11.1 (Feb 05 2010 - 08:57:12)

Hit any key to stop autoboot:  0

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.

ALERT! In some cases you may see a message

*** Warning - bad CRC, using default environment

This is harmless and will go away as soon as you have initialized and saved the environment variables.

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:

=> setenv ethaddr !!!!!!FILL_THIS!!!!!!
=> setenv serial# 86BA-5AA1-BD9

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

=> printenv serial# ethaddr
## Error: "serial#" not defined

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:

=> saveenv
