5 Firmware changes and upgrades
The firmware which is loaded onto the integrated ETRX2 Module can be upgraded over the air or
via Ethernet using a virtual COM port as described in the Development Kit Manual. The procedure
for bootloading is described in section 12 of the Telegesis Development Kit Product Manual
(available from our website). If you want to bootload new firmware via the COM port, you must
take care to follow this procedure, because the Telegesis firmware and the Ember bootloader run
at different baud rates:
Start Lantronix DeviceInstaller, CPR Manager and Telegesis Terminal
Set up a normal serial COM port connection from Telegesis Terminal to the EAP
Execute AT+BLOAD
Disconnect Telegesis Terminal
Use DeviceInstaller to change Lantronix Ethernet module to 115200 baud, as described in
section 4
Connect Telegesis Terminal but stay at 19200 baud
Hit <cr> and get the usual bootloader prompts
Download new firmware at 19200
Disconnect Telegesis Terminal
Use DeviceInstaller to change Lantronix module back to 19200 baud
Connect Telegesis Terminal
Resume normal operation with new firmware
Alternatively access to the SIF programming interface is possible by removing the cover of the
EAP-E access point. You can also use this interface for custom firmware development and real
time debugging of your custom firmware.
Finally with the advent of EmberZNet3.x it is now possible to download the Ember EZSP (Ember
ZigBee® Serial Protocol) as described in section 6 of the EM260 manual to the EAP-E. In case
you require an EAP-E with pre-loaded EZSP firmware please contact
.
5.1 Device Reset and manually Entering the Bootloader
In case the embedded ETRX2 needs to be reset manually the reset pin of the ETRX2 is connected
to the CP1 pin of the Lantronix® XPort® Direct
TM
module in the same way as the A/D2 pin is
connected to the CP2 pin. This allows hardware triggering of the Ember standalone bootloader,
which can be used for firmware upgrades.
To learn how to access the CP1 and CP2 Pin of the Lantronix® XPort® Direct
TM
module please
refer to the Lantronix® XPort® Direct
TM
user guide.
