16.0 U-Boot Update
The update of the device servers U-Boot code is an infrequent event, however when
required the following procedure must be followed. Delivery of the U-Boot image can be
made using either the FTP or Xmodem update process. This procedure may be used for
U-Boot versions v1.0.0 and higher, if your unit has a U-Boot earlier than this please
contact B&B Electronics Technical support.
To successfully achieve the U-Boot update the sequence identified in Table 32 must be
followed.
The update cannot be done from the web interface, it is required that a CLI session on
the network or serial interface be used to initiate the U-Boot update process.
The FTP update process requires that the unit is successfully associated to a wireless
network.
Table 32- U-Boot Update Process
Step/Command Description
ver-uboot Issuing the ver-uboot command will allow identification of the current U-

U-Boot 1.3.2 (Jul 16 2009 - 15:41:48) Quatech WLNx-9260 1.1.1
The above version of U-Boot is v1.1.1
Obtain U-Boot .img
file The U-boot file can be downloaded from the B&B Electronics Support
website or requested from B&B Electronics Technical support.
Configure FTP Server If using the FTP client to download the U-Boot firmware image, an FTP
server is required to deliver the u-boot file to the module. This server must
be on the same network and subnet as the module being updated.
An account for the unit must be set-up, the username and password will be
needed for configuration of the module.
The U-Boot file should be placed in the home directory of the FTP account.
If this is not possible the actual directory path from the home directory will
need to be known for the configuration of the module.
Configure Airborne
device
If using the FTP client to download the U-Boot firmware image the module
will need the FTP settings configured. See section 14.0 for details of how to
do this.
It is not necessary to commit the FTP settings to the Airborne unit before
using. However of not saved they will be lost on any restart or power cycle.
update-uboot [option] Issue the update-uboot command with either the FTP or Xmodem update
option.
If [option] is ftp the device will download the U-Boot image from the
FTP server and automatically start the update process. This requires that the
FTP settings are already configured and correct.
If [option] is xmodem the device will wait for an Xmodem transfer to be
initiated by the connected host. The U-Boot image file will then be uploaded
and the module will automatically start the update process.
