Note:
Sometimes the SAM7X will retain old FLASH values such as IP
addresses. This can be a valuable feature during code reloads to keep
static variables. To ensure that the memory is purged, the Erase jumper
on the SAM7X board can be connected to ground. Doing so will
completely erase the memory and will ensure that reloaded code will
implement new values.
D.3 Eclipse IDE
D.3.1 Required Tools
Besides the RUM source code, a few external tools are needed. These tools are the
compiler and associated toolchain, the graphical interface, the emulator interface, and
the FLASH programming tool.
D.3.1.1 YAGARTO
YAGARTO is a GCC compiler distribution. Download the latest version of the
“YAGARTO GNU ARM toolchain” from www.yagarto.de
. Their website also has links
to other documentation on setting up the toolchain.
D.3.1.2 Eclipse
Eclipse is the graphical interface that will be used. Get the C/C++ Edition from
www.eclipse.org/downloads/
.
D.3.1.3 J-Link Software and Documentation Pack from Segger
This provides the GDB-Server that allows the Atmel SAM-ICE to be used for
debugging. Obtain the software pack from Segger at
www.segger.com/download_jlink.html
.
D.3.1.4 AT91SAM-ICE (SAM-PROG)
The SAM-PROG
TM
utility allows programming the FLASH memory in the SAM7X
device using the Atmel SAM-ICE. Get the latest version of the “AT91-ISP.exe‟ from
www.atmel.com/dyn/products/tools.asp?family_id=605
.
D.3.2 Installing
Run th
e provided installers for each tool. With Eclipse there is no install needed – just
extract the folder and create a shortcut to the eclipse.exe program.
D.3.3 Building RUM – Step by Step
Start the Eclipse p
rogram; a splash screen should appear.
If no splash screen appears, there may be a problem with the Java
®
Runtime
Environment. Check the Eclipse documentation on eclipse.org for more details.
Eclipse will then ask for the “workspace”, which is where it stores all its projects.
