In bootloader mode, the command line interface’s prompt is the
character
>. Therefore, to reboot the RTU just type the following after
you see the > prompt:
reboot
An alternative way to boot the RTU is to disconnect the battery and
after a few seconds reconnect it.
For a list of the available commands, type Help at the > prompt.
Available commands:
upgrade [baudrate] ... upgrade from Y-modem download
version ... show the version of the bootloader
state ... show the board state
reboot [id] ... reboot the RTU
firmware ... start the firmware
help ... display this help text
Note: For some commands, such as the reboot command, you can supply
the ID of the RTU.
FirmwareMode
When you enter firmware mode, the following message is displayed in
the Hyperterminal window:
Checking firmware ... firmware found!
41239 0
#
The bootloader scans the program memory for a valid firmware by
testing the checksum, which takes a moment. If everything is correct,
the "firmware found!" message appears.
A moment after the firmware is found, the RTU’s identification number
(for example, 41239) and error code (in this example, 0) are
displayed. After another moment, the firmware mode’s command line
interface prompt is displayed (#).
If you need to return to bootloader mode when you’re in firmware
mode, enter the Reboot <ID> command at the prompt.
See “Using terminal commands” on page 24 for commands available
in firmware mode.
