6 BNA Bootloader
This chapter describes the functions of the BNA
Bootloader software. Each BNA device is equipped
with a Bootloader, which functions in the same way
for all BNA device types.
Note: BNA Devices are not equipped with any
application firmware. This must be loaded into
the device prior to using it.
6.1
Startup Behavior
After resetting or power-on the BNA device, all
LEDs on the front will be switched on. Immediately
after that, the BNA Bootloader starts working.
When the BNA Bootloader is active, the heartbeat
LED on the BNA front panel flashes RED.
In contrast, any running application firmware
indicates its execution with a GREEN flashing
heartbeat LED.
The Flowchart depicted in Figure 6-1 explains the
BNA execution sequence. It is necessary that the
user understand this in order to be able to react to
or influence the behavior of the BNA device.
Furthermore, it helps understanding in which state
the device currently is while looking at the LEDs on
the front panel of the BNA.

6.2
Operating Modes
The BNA Bootloader provides two different
operating modes:
•
•
Normal Mode
Stay in Bootloader Mode
(default)
Normal Mode is the default, which directly starts an
application firmware found in Flash memory. If no
firmware could be found, then the bootloader
command shell is started by the BNA (Figure 6-1).
This execution flow can only be influenced by
pressing the Mode Button and changing the mode
to Stay in Bootloader Mode.
Stay in Bootloader Mode interrupts the default
bootloader startup sequence and tells the
bootloader not to start an eventually existing
application firmware in the Flash memory.
6.3
Switching the Operating Mode
In order to switch the Bootloader operating mode, a
pointed object, like an unfolded paper clip or a
sharp pen is required.
For changing the operating modes, there is a time
window of about
3
seconds after reset. The
following steps have to be performed to
successfully change the bootloader mode (Refer
also to Figure 6-2: Switching BNA Operating Mode):
1. Press the Reset Button
EN1B-0198GE51 R0801

BUILDING NETWORK ADAPTER BNA-1C/2CS/2DN
2. Wait till the heartbeat LED starts flashing RED,
then press the Mode Button.
3. The heartbeat flashing immediately stops and
the LED is permanently on. The operating
modes are displayed using the LAN status
LEDs Lnk, Tx, Rx. The Normal Mode is
represented via the Lnk LED.
4. Now push the Mode Button again and the Tx
LED will also be switched on. Two LEDs on
means Stay in Bootloader Mode is selected.
5. To accept one of the modes, push the Mode
Button again and hold it for about 1 second.
The BNA Bootloader feedback that the mode
has been accepted is indicated with all Mode
LEDs and the heartbeat LED flashing four
times.
If there is no need to change the mode after the
mode button has been pressed, then just stop
pressing the mode button. The BNA device will
continue with its normal work after a few seconds.

server. This is necessary for loading the
application firmware into the BNA
device.
load
Load executable from FTP server
This command finally loads the
application firmware (executable) into
the BNA device. After successful
download, the application firmware is
moved into the Flash memory.
This is the minimum command sequence for setting
up a BNA device.
After that the application firmware can be invoked
by entering the command run or by pushing the
Reset button. When the Reset button is pushed, the
BNA Bootloader behaves as depicted in Figure 6-1
on Page 24.

As mentioned above, the three commands are the
minimum required commands for setting up a
BNA device. We recommend also performing some
user definitions (see command um) for different
user roles. Doing so prevents unfamiliar users from
performing accidental redefinition of important
settings. Furthermore, user definitions can also be
referenced by the application firmware.

Command Description
The BNA Bootloader provides a command shell
allowing input of several commands. Some of the
commands are providing sub-shells which
themselves are providing another set of commands
to enter.
This chapter describes all BNA Bootloader
commands in detail. The order of the command
descriptions in this chapter follows the order of the
commands displayed by the BNA Bootloader shell
except for the command help. This has been placed
into the first position because it is necessary to get
the list of commands displayed.
The following notational conventions apply to this
chapter unless otherwise noted:
cmd
Bootloader command
<key>
A key that has to be pressed, like
<Enter>.

All command lists can vary between different users.
The lists don’t show any commands which a user is
not allowed to execute.
6.5.2 np - Basic network parameters
The basic network parameters command np is used
to define the IP address, the network mask, and the
default gateway of the BNA device. This
information is normally provided by the local IS
department.
np is not a direct command; instead, it provides a
sub-shell with the following commands:

requested information, it will be asked
whether to take over the new settings.
If this is denied the old settings will be
restored. Otherwise, the new settings
are stored to the Flash memory and the
system needs to be restarted to activate
the new settings.
delete
deletes basic network settings. Please
note that after this operation the BNA
device will not operate on the LAN
anymore. After commanding delete,
new basic network parameters must be
entered via modify.
altmac
definition of an alternative MAC-
address. This command is available
only for the sake of completeness. Each
BNA already comes with
a
unique
Ethernet address (MAC address). So
there will be no need for defining a new
MAC address. It is recommended to
not use this command unless advised to
do so by the Hone ywe ll Technical
Assistance Center.

application firmware versions when an update of
the same becomes necessary.
Command dc defines the IP address of the FTP-
Server, the path to the application firmware, a
username on the FTP-Server and the user’s
password. This command must be invoked prior to
using command load.
Prerequisite for downloading an application
firmware is
a
running FTP-Server machine
somewhere in the network that can be reached by
the BNA device. The FTP-Server machine is
responsible for storing the application firmware
image that shall be loaded into the BNA device. The
application firmware image for the BNA is
delivered on the distribution media of the Building
Management System that is currently used.
The description of how to setup and invoke an FTP-
Server on each specific operating system is not
within the scope of this document. Please refer to
the documentation set of the operating system used
on the machine that has been selected for the role of
the FTP-Server.

exits the sub-shell and returns to the
main shell.
6.5.4 load - Load executable
The command load is a direct command which
immediately starts downloading the application
firmware image into the BNA based on the
download configuration defined by the command dc.
After loading the image into local memory the BNA
Bootloader starts copying the image into the local
Flash memory where it resides until updated the
next time.
load accepts optional command-line parameters.
Accepted command-line parameters are FTP-Server
IP-Address
and/or
filename.
Command-line
parameters supersede the current download
configuration for these elements. Command-line
parameters in the load command scope can be used
to use an alternative FTP-Server for downloading
or to download another application firmware
image into the BNA device.
If load fails, then it needs to be checked whether the
correct download configuration has been defined.
In this case, the command dc test becomes useful.

6.5.5 ping - ping
Sends an ICMP Ping through TCP/IP to the FTP-
Server defined in the download configuration or to
the machine addressed by the IP-Address in the
optional command-line parameter.
This command can be used to check whether the
network connection is working properly.
6.5.6 ver - Show installed software
The command ver outputs a list of all installed
software components on the current BNA device.
6.5.7 run - Execute installed software
The command run starts
a
previously-installed
application firmware.
If no application firmware could be found, then the
information No executable found is printed
out. In this case, use load to download an
application firmware.
6.5.8 um - User management
The user management command um allows the
definition of users, different access rights per user
and user individual password settings.
User definitions are necessary to provide a secure
device on an open TCP/IP network. Furthermore it

may not be desired that every user will be allowed
to do everything with a BNA device.
These user accounts are required only for set-up,
configuration and diagnostic applications if
available. The communication protocols allowing
the communication between BNA and its building
management system are protected at the protocol
level depending on the type of application
firmware.
It is recommended to define several user roles
because also an application firmware may use these
user definitions to behave different in potentially
provided user interfaces depending on the user
who is currently logged in.
A BNA device allows up to 5 user definitions with
different access rights. The root user already
occupies one of these
5
definitions. Thus,
4
additional users or better to say user roles can be
defined.
A user definition consists of three elements. These
are a username or role name, a group membership
and finally a password.
Usernames and password are freely definable. Both
are maximal 8 character long. Whereas the group
definitions are predefined each of it has specific
characteristics.
Table 6-2 gives an overview of the available user
groups and their properties.

7.2.2 AUI Connector
The AUI (Attachment Unit Interface) offers an
alternative way of connecting the BNA device to
the Ethernet regardless which Ethernet medium or
technique it uses.
In older network installations Ethernet devices can
be connected directly using a 78 Ω cable to specific
Hubs. In such an environment, the AUI cable
length must not exceed 50m. The end of this 78 Ω
cable is outlet into a 15-pin connector (refer to
Table 7-2).

Tips & Tricks
Tip 1
To simplify downloading, we re-
commend reducing (renaming) the
application firmware image name to
the base name of the image in the FTP-
Server publication directory, e.g.
rename bna_susi_server_v1.0.0.bin to
bna_susi_server.bin.
This has the advantage that even when
updates or upgrades of the application
firmware are delivered, no change is
necessary in each BNA download
configuration.
Tip 2
The BNA Bootloader command shell is
able to execute commands in a sub-
shell directly. For example, it is possible
to invoke the command display in sub-
command shell np directly from the
BNA Bootloader prompt. Just call:
BNA bootloader> np display
followed by <Enter>.
Tip 3
The BNA Bootloader command shell
allows execution of more than one
command by using a “;” between two
commands, e.g.: np display; dc display
<Enter>. When one of the commands
fails, execution is stopped at this point.

FAQs
1. Which terminal type can be used for
connecting to the BNA Bootloader?
For connecting to the BNA Bootloader, any
VT100 compatible terminal or VT100
compatible terminal emulation program can be
used. For the proper terminal settings, please
refer to chapter 6.4 Device Setup on Page 28.
2. After power-on or reset, the BNA device does
not show the BNA bootloader menu on my
terminal. How do I get the correct display?
One reason could be that the terminal settings
are not correct. Please verify the actual terminal
settings. For the proper terminal settings please
refer to chapter 6.4 Device Setup on Page 28.
A second reason could be that an application
firmware is already running in your BNA. As
described in chapter 6.1 Startup Behavior on
Page 23 BNA will start an application firmware
automatically after power-on or reset. To access
bootloader mode, it is required to switch the
operating mode to force the BNA to Stay in
Bootloader Mode. Please refer to chapter
6.3 Switching the Operating Mode on Page 25 for
further information.
