6 BNA Bootloader

This chapter describes the functions of the BNABootloader software. Each BNA device is equippedwith a Bootloader, which functions in the same wayfor all BNA device types.

Note: BNA Devices are not equipped with anyapplication firmware. This must be loaded intothe device prior to using it.

6.1 Startup BehaviorAfter resetting or power-on the BNA device, allLEDs on the front will be switched on. Immediatelyafter that, the BNA Bootloader starts working.

When the BNA Bootloader is active, the heartbeatLED on the BNA front panel flashes RED.

In contrast, any running application firmwareindicates its execution with a GREEN flashingheartbeat LED.

The Flowchart depicted in Figure 6-1 explains theBNA execution sequence. It is necessary that theuser understand this in order to be able to react toor influence the behavior of the BNA device.Furthermore, it helps understanding in which statethe device currently is while looking at the LEDs onthe front panel of the BNA.

EN1B-0198GE51 R0801 25

6.2 Operating ModesThe BNA Bootloader provides two differentoperating modes:

• Normal Mode (default)• Stay in Bootloader Mode

Normal Mode is the default, which directly starts anapplication firmware found in Flash memory. If nofirmware could be found, then the bootloadercommand shell is started by the BNA (Figure 6-1).This execution flow can only be influenced bypressing the Mode Button and changing the modeto Stay in Bootloader Mode.

Stay in Bootloader Mode interrupts the defaultbootloader startup sequence and tells thebootloader not to start an eventually existingapplication firmware in the Flash memory.

6.3 Switching the Operating ModeIn order to switch the Bootloader operating mode, apointed object, like an unfolded paper clip or asharp pen is required.

For changing the operating modes, there is a timewindow of about 3 seconds after reset. Thefollowing steps have to be performed tosuccessfully change the bootloader mode (Referalso to Figure 6-2: Switching BNA Operating Mode):

1. Press the Reset Button


26 EN1B-0198GE51 R0801

2. Wait till the heartbeat LED starts flashing RED,then press the Mode Button.

3. The heartbeat flashing immediately stops andthe LED is permanently on. The operatingmodes are displayed using the LAN statusLEDs Lnk, Tx, Rx. The Normal Mode isrepresented via the Lnk LED.

4. Now push the Mode Button again and the TxLED will also be switched on. Two LEDs onmeans Stay in Bootloader Mode is selected.

5. To accept one of the modes, push the ModeButton again and hold it for about 1 second.The BNA Bootloader feedback that the modehas been accepted is indicated with all ModeLEDs and the heartbeat LED flashing fourtimes.

If there is no need to change the mode after themode button has been pressed, then just stoppressing the mode button. The BNA device willcontinue with its normal work after a few seconds.

6.4 Device SetupIn order to setup the BNA device properly, thefollowing connections are necessary:

• DB9F Null-Modem cable connected to a PCrunning a VT100 terminal emulation program or aVT100 compatible terminal (refer to Table 6-1:Terminal settings)

• LAN connection either via UTP (RJ45 connector) orAUI.

• Power connection.• An active FTP-Server machine on the LAN

Terminal type: VT100

Bits per second: 115200

Data bits: 8

Parity: none

Stop bits: 1

Flow control: none

Table 6-1: Terminal settings

After having connected all necessary cables to theBNA, press the Reset button. If the terminal settingsare all Ok, the Copyright notice of the BNA devicewill be displayed.


EN1B-0198GE51 R0801 29

If this is the very first run of the device, then theCopyright notice is followed by the query for theroot user password. At the Old password:prompt just hit the Enter-Key.

Once a password has been defined the BNA printsthe information User 'root' logged in. forall future startups.

The root user is the administration user withunlimited access rights. The root user will be loggedin automatically without any login procedure whenconnecting to the BNA device via the serial link(RS232). Any connection to the BNA via LAN ispassword protected!

If the device already contains an applicationfirmware, then it is necessary to put the device intothe Stay in Bootloader Mode prior to the setupactivity (refer to chapter 6.3 Switching the OperatingMode on Page 25 how this can be done).

To prepare the BNA device to operate on the LANand to load the application firmware into thedevice, the following mandatory commands mustbe executed in the order they are listed (for adetailed command description, refer to chapter6.5 Command Description on Page 31):

np Basic network parametersDefinition of IP address, network maskand default gateway. These definitionsare required to allow the BNA device tooperate on the LAN.


30 EN1B-0198GE51 R0801

CAUTION:

Using not-allowed IP-Addresses could causeinterference on the network.

Please contact your network administrator toretrieve a unique IP-Address. In case you want toconnect the BNA to a customer network makesure to get in touch with the customers ITmanager to retrieve this IP-Address information.

dc Download configurationDefinition of FTP server, path tofirmware and user account on FTPserver. This is necessary for loading theapplication firmware into the BNAdevice.

load Load executable from FTP serverThis command finally loads theapplication firmware (executable) intothe BNA device. After successfuldownload, the application firmware ismoved into the Flash memory.

This is the minimum command sequence for settingup a BNA device.

After that the application firmware can be invokedby entering the command run or by pushing theReset button. When the Reset button is pushed, theBNA Bootloader behaves as depicted in Figure 6-1on Page 24.


EN1B-0198GE51 R0801 31

As mentioned above, the three commands are theminimum required commands for setting up aBNA device. We recommend also performing someuser definitions (see command um) for differentuser roles. Doing so prevents unfamiliar users fromperforming accidental redefinition of importantsettings. Furthermore, user definitions can also bereferenced by the application firmware.

6.5 Command DescriptionThe BNA Bootloader provides a command shellallowing input of several commands. Some of thecommands are providing sub-shells whichthemselves are providing another set of commandsto enter.

This chapter describes all BNA Bootloadercommands in detail. The order of the commanddescriptions in this chapter follows the order of thecommands displayed by the BNA Bootloader shellexcept for the command help. This has been placedinto the first position because it is necessary to getthe list of commands displayed.

The following notational conventions apply to thischapter unless otherwise noted:

cmd Bootloader command

<key> A key that has to be pressed, like<Enter>.


32 EN1B-0198GE51 R0801

Text Text written with this font showsterminal output.

Note: All BNA Bootloader commands are case-sensitive!

6.5.1 Help or ?

Entering help or ? at the BNA bootloader>prompt followed by <Enter> displays all availableBNA Bootloader commands.

In each sub-shell help or ? can also be used to viewthe existing commands.

All command lists can vary between different users.The lists don’t show any commands which a user isnot allowed to execute.

6.5.2 np - Basic network parameters

The basic network parameters command np is usedto define the IP address, the network mask, and thedefault gateway of the BNA device. Thisinformation is normally provided by the local ISdepartment.

np is not a direct command; instead, it provides asub-shell with the following commands:

display displays current basic network settings.

modify changes basic network settings. Afterentering this command each basicnetwork parameter will be queried


EN1B-0198GE51 R0801 33

individually. After having entered allrequested information, it will be askedwhether to take over the new settings.If this is denied the old settings will berestored. Otherwise, the new settingsare stored to the Flash memory and thesystem needs to be restarted to activatethe new settings.

delete deletes basic network settings. Pleasenote that after this operation the BNAdevice will not operate on the LANanymore. After commanding delete,new basic network parameters must beentered via modify.

altmac definition of an alternative MAC-address. This command is availableonly for the sake of completeness. EachBNA already comes with a uniqueEthernet address (MAC address). Sothere will be no need for defining a newMAC address. It is recommended tonot use this command unless advised todo so by the Honeywell TechnicalAssistance Center.

exit exits the sub-shell and returns to themain shell.

6.5.3 dc - Download configuration

The download configuration command dc is usedto have a predefined way of retrieving new


34 EN1B-0198GE51 R0801

application firmware versions when an update ofthe same becomes necessary.

Command dc defines the IP address of the FTP-Server, the path to the application firmware, ausername on the FTP-Server and the user’spassword. This command must be invoked prior tousing command load.

Prerequisite for downloading an applicationfirmware is a running FTP-Server machinesomewhere in the network that can be reached bythe BNA device. The FTP-Server machine isresponsible for storing the application firmwareimage that shall be loaded into the BNA device. Theapplication firmware image for the BNA isdelivered on the distribution media of the BuildingManagement System that is currently used.

The description of how to setup and invoke an FTP-Server on each specific operating system is notwithin the scope of this document. Please refer tothe documentation set of the operating system usedon the machine that has been selected for the role ofthe FTP-Server.

dc is not a direct command; instead, it provides thefollowing commands in a sub-shell:

display displays current download configura-tion.

modify changes download configuration. Afterentering this command each downloadconfiguration item will be queried


EN1B-0198GE51 R0801 35

individually. After having entered allrequested information it will be askedwhether to take over the new settings.If this is denied the old settings will berestored. Otherwise, the new settingsare stored to the Flash memory. Thesesettings are immediately active.

delete delete download configuration. Afterthis operation command load can’t beused anymore. New download con-figuration definitions must be enteredusing the command modify.

test tests current download configuration.This command can be used to checkwhether the entered downloadconfiguration is valid or not.

With the command test, optionalcommand-line parameters are allowed.Accepted parameters are FTP-Server IP-Address and/or a filename for checkingexistence. Given command-lineparameters are temporarilysuperseding the values in the actualdownload configuration.

Note: With some Windows NTbased FTP-Servers it has beenobserved that this command failssometimes the first time. If so, werecommend trying it for a second time.After that the conclusion that one of


36 EN1B-0198GE51 R0801

the parameters may be wrong isacceptable.


6.5.4 load - Load executable

The command load is a direct command whichimmediately starts downloading the applicationfirmware image into the BNA based on thedownload configuration defined by the command dc.

After loading the image into local memory the BNABootloader starts copying the image into the localFlash memory where it resides until updated thenext time.

load accepts optional command-line parameters.Accepted command-line parameters are FTP-ServerIP-Address and/or filename. Command-lineparameters supersede the current downloadconfiguration for these elements. Command-lineparameters in the load command scope can be usedto use an alternative FTP-Server for downloadingor to download another application firmwareimage into the BNA device.

If load fails, then it needs to be checked whether thecorrect download configuration has been defined.In this case, the command dc test becomes useful.


EN1B-0198GE51 R0801 37

6.5.5 ping - ping

Sends an ICMP Ping through TCP/IP to the FTP-Server defined in the download configuration or tothe machine addressed by the IP-Address in theoptional command-line parameter.

This command can be used to check whether thenetwork connection is working properly.

6.5.6 ver - Show installed software

The command ver outputs a list of all installedsoftware components on the current BNA device.

6.5.7 run - Execute installed software

The command run starts a previously-installedapplication firmware.

If no application firmware could be found, then theinformation No executable found is printedout. In this case, use load to download anapplication firmware.

6.5.8 um - User management

The user management command um allows thedefinition of users, different access rights per userand user individual password settings.

User definitions are necessary to provide a securedevice on an open TCP/IP network. Furthermore it


38 EN1B-0198GE51 R0801

may not be desired that every user will be allowedto do everything with a BNA device.

These user accounts are required only for set-up,configuration and diagnostic applications ifavailable. The communication protocols allowingthe communication between BNA and its buildingmanagement system are protected at the protocollevel depending on the type of applicationfirmware.

It is recommended to define several user rolesbecause also an application firmware may use theseuser definitions to behave different in potentiallyprovided user interfaces depending on the userwho is currently logged in.

A BNA device allows up to 5 user definitions withdifferent access rights. The root user alreadyoccupies one of these 5 definitions. Thus, 4additional users or better to say user roles can bedefined.

A user definition consists of three elements. Theseare a username or role name, a group membershipand finally a password.

Usernames and password are freely definable. Bothare maximal 8 character long. Whereas the groupdefinitions are predefined each of it has specificcharacteristics.

Table 6-2 gives an overview of the available usergroups and their properties.


EN1B-0198GE51 R0801 39

user View only rights.

Users who are member of this groupare not allowed to change or deleteany existing definition.

priv Privileged rights.

Users of the privileged group areallowed to change several definitionslike network parameters but they arenot allowed to perform deleteoperations. Furthermore privilegedusers have no right to perform anyuser management.

admin Administrative users.

Administrative users have full rights.The root user belongs to the admingroup.

Table 6-2: BNA user groups

The user management command um is an indirectcommand and provides the following commands inits sub-shell:

display display current user definitions.

add add new user. The username canoptionally be passed directly on thecommand-line.


40 EN1B-0198GE51 R0801

delete deletes existing user. The username canoptionally be passed directly on thecommand-line. Furthermore an option–all is available that deletes all userdefinitions except the one for the rootuser. The root user account can’t bedeleted.

setpass set other user’s password. Thiscommand is helpful when a user hasforgotten his password. The usernamecan optionally be passed directly on thecommand-line.

passwd set own password. Every user can usethis command to change his ownpassword.


6.5.9 whoami - Who am I

whoami prints username and group of the usercurrently logged in.

6.5.10 login - Login as different user

The command login allows users to change theirrole while they are connected to a BNA device.

This command is not that much useful whileconnected via the RS232 port because in this casethe root user is logged in per default. In case of


EN1B-0198GE51 R0801 41

using bootloader functionality via a network whichcan be provided by the application firmware, thiscommand becomes more interesting.

7.2 Ethernet Connectors

Figure 7-3: BNA Ethernet connectors

The BNA provides two different types ofconnectors to bring the device online on the LAN.First is a RJ45 10BaseT connector and second is anAUI connector. This chapter describes the pinlayout of each connector type and shows how thedifferent cables need to be configured especially forthe connection via 10BaseT (RJ45).

7.2.1 RJ45 Connector

A lot of Ethernet local area networks are using10BaseT twisted pair wiring. 10BaseT networks arephysically laid out in a star topology, where each


EN1B-0198GE51 R0801 45

piece of equipment on the network is connected toa central hub. The wiring is connected to devicesusing a plug that resembles a phone jack, calledRJ45.

7.2.2 AUI Connector

The AUI (Attachment Unit Interface) offers analternative way of connecting the BNA device tothe Ethernet regardless which Ethernet medium ortechnique it uses.

In older network installations Ethernet devices canbe connected directly using a 78 Ω cable to specificHubs. In such an environment, the AUI cablelength must not exceed 50m. The end of this 78 Ωcable is outlet into a 15-pin connector (refer toTable 7-2).


48 EN1B-0198GE51 R0801

Nowadays the AUI is used to connect a smalldevice called transceiver, which adapts between theAUI on the device and the Ethernet medium usedin the current installation.

Tips & Tricks

Tip 1 To simplify downloading, we re-commend reducing (renaming) theapplication firmware image name tothe base name of the image in the FTP-Server publication directory, e.g.rename bna_susi_server_v1.0.0.bin tobna_susi_server.bin.

This has the advantage that even whenupdates or upgrades of the applicationfirmware are delivered, no change isnecessary in each BNA downloadconfiguration.

Tip 2 The BNA Bootloader command shell isable to execute commands in a sub-shell directly. For example, it is possibleto invoke the command display in sub-command shell np directly from theBNA Bootloader prompt. Just call:

BNA bootloader> np displayfollowed by <Enter>.

Tip 3 The BNA Bootloader command shellallows execution of more than onecommand by using a “;” between twocommands, e.g.: np display; dc display<Enter>. When one of the commandsfails, execution is stopped at this point.

FAQs

1. Which terminal type can be used forconnecting to the BNA Bootloader?

For connecting to the BNA Bootloader, anyVT100 compatible terminal or VT100compatible terminal emulation program can beused. For the proper terminal settings, pleaserefer to chapter 6.4 Device Setup on Page 28.

2. After power-on or reset, the BNA device doesnot show the BNA bootloader menu on myterminal. How do I get the correct display?

One reason could be that the terminal settingsare not correct. Please verify the actual terminalsettings. For the proper terminal settings pleaserefer to chapter 6.4 Device Setup on Page 28.

A second reason could be that an applicationfirmware is already running in your BNA. Asdescribed in chapter 6.1 Startup Behavior onPage 23 BNA will start an application firmwareautomatically after power-on or reset. To accessbootloader mode, it is required to switch theoperating mode to force the BNA to Stay inBootloader Mode. Please refer to chapter6.3 Switching the Operating Mode on Page 25 forfurther information.
