The following section assumes that flash memory is used as the storage
device for the firmware on your board. If this is not the case, the
following instructions will not work - you will probably have to
replace the storage device (probably ROM or EPROM) on such systems to
install or update U-Boot.
All canyonlands boards use a serial number for identification purposes. Also, all boards have at least one ethernet (
MAC) address assigned. You may lose your warranty on the board if this data gets lost. Before installing U-Boot or otherwise changing the software configuration of a board (like erasing some flash memory) you should make sure that you have all necessary information about such data.
