Description Updates the devices U-Boot firmware.
If update-uboot is issued without an argument the module will operate as if the xmodem argument had
been used for the update.
 Only firmware authorized by B&B Electronics should be used with this command. Any
attempt to use an alternative image will void the modules warranty.
Requires configuration of the FTP client settings prior to being issued.
xmodem
The module expects an Xmodem or Xmodem-1K transfer to be initiated by a
host on the connected ports. The file transfer must be the U-Boot update file
from B&B Electronics.
ftp
The module will use the configured FTP settings and attempt to download
the U-Boot update image.
The ftp-filename must match the firmware image being down loaded, e.g.
ftp-filename u-boot.ver01_01_02.img
The device must be restarted or power cycled once the update process has completed.

CRITICAL: When updating any firmware, power must be maintained during the entire
update process. Removal or interruption of the power supply may cause a corruption of
the firmware update and cause the module to stop functioning. If this occurs please
contact B&B Electronics Technical Support.
