10.3.3.2 Application workspace
1. Double-click on a workspace (for example,
zseApp.eww
), and select
JTAGICE
mkII > Fuse Handler
(
JTAGICE 3 > Fuse Handler
)
2. Click
Read Fuses
, and make sure that the device fuses are set as specified in
3. If fuses are set incorrectly, select the correct fuse settings, and click
Program
fuses
4. Select the desired application configuration (for example,
All_StdlinkSec_Stk600_
ATmega128RFA1_Rf231_16Mhz
) from the drop-down
box in the
Workspace
pane
5. Select
Project > Download and debug
6. Once the debugging session has started, click
Stop debugging
The image is now installed on the board.
NOTE
Using a JTAG to program the microcontroller will erase the embedded bootloader, if
present. As a result, loading of application images with Serial Bootloader will become
inoperable until the embedded bootloader is loaded to ATmega128RFA1 again.
10.3.4 Programming with AVR Studio
1. In AVR Studio, open the
Tools > Program AVR > Connect…
dialog
2. Choose JTAGICE mkII (JTAGICE 3) for
Platform:
and USB for
Port:
, and click
Connect…
3. Select the right device (ATmega128RFA1) in the Device and Signature Bytes
field on the
Main
tab of the programming dialogue
4. Click on the
Fuses
tab and make sure that the device fuses are set as specified in
5. If fuses are set incorrectly, select the correct fuse settings, and click
Program
6. Click on the
Program
tab
7. In the Flash section of the dialog, select the precompiled
.hex
file to be
programmed
8. Click
Program
The image is now installed on the board.
10.3.5 Programming with Serial Bootloader
Programming using Serial Bootloader requires that the embedded bootloader code is
loaded to the device via JTAG. Firmware images for the embedded bootloader as
well as the Bootloader PC tool, which is needed to load the application image from a
PC to the device, are included in the Atmel Serial Bootloader software package
available for downloading from the Atmel website.
Images that shall be loaded to ATmega128RFA1 via JTAG may be found under the
Images that shall be loaded to ATmega128RFA1 via JTAG may be found under the
\Embedded_Bootloader_images\Atmega128rfa1
directory in the package:
•
The
Bootloader_ATmega128RFA1_RCB_BB_RS232.hex
file for RCB128RFA1
•
The
Bootloader_ATmega128RFA1.hex
file for ATAVR128RFA1-EK1
In both cases, the fuse bits should be configured properly; namely, the
BOOTRST fuse
If the embedded bootloader is loaded, the following steps should be executed to
upload the application image file to the board:
1. Assemble the board and connect it to a PC:
