In the previous posts I showed how to
get started with Nuttx and set up and test simple network features,
here I would like to show how to integrate Nuttx building environment
with Eclipse.
First of all we need to download
Eclipse and, of course JRE (Java Runtime Environment) that is used to
run Eclipse.
Please refer to the following links to
download all the necessary:
In the specific I used JRE Version
1.8.0_31 end Eclipse Luna SR2.
In order to install Eclipse we just
need to unzip and untar the tarball downloaded.
I did it in my home directory:
#cd
#tar zxvf
eclipse-cpp-luna-SR2a-linux-gtk.tar.gz
and install JRE:
#cd eclipse/
#tar zxvf jre-8u31-linux-i586.tar.gz
# mv jre1.8.0_31 jre
Let's now move on the top of the home
directory
# cd ..
and let's create a simple and
convenient text file to launch Eclipse.
Use your preferred text editor and
create a text file starteclipse containing:
PATH=/home/user/nuttx_workdir/nuttx-code/misc/buildroot/build_arm/staging_dir/bin:/home/user/nuttx_workdir/nuttx-stellaris/misc/buildroot/build_arm_nofpu/staging_dir/bin:$PATH
./eclipse/eclipse
#chmod +x starteclipse
and launch it:
#./starteclipse
If everything went right you should see
eclipse appearing on your desktop.
We can now import Nuttx building
environment in it:
As showed in the screen-shoot below
select File->New->Makefile Project with Existing Code
A wizard will pop up, be sure to fill
it with Project Name ad Existing Code Location and press Finish.
Now in the Project explorer you will
see the Nuttx project, right-click it and select Properties from the
context menu:
Select Environment on the Properties
Windows and add a New Environment Variable as showed in the picture:
CROSSDEV= arm-elf-, basically we are setting the same environment as
we do from command line (see the previous post).
Press OK on the “New Variable”
window and OK on the “Properties” window.
We are now ready, we can build Nuttx
within Eclipse, just right click the Build in the context Menu
You can now “Clean Project” or
modify it and “Rebuild Project” in a easy and handy way.
I also found really handy to launch
the simulator inside Eclipse; in order to do it, select Run->External
Tools->External Tools Configuration...
Here you can instruct Eclipse, to launch
Qemu emulating the Stellaris platform and run Nuttx image.
In the Windows that will appear:
- select New,
- give a Name (e.g. start_qemu_stellaris),
- select the location where Qemu has been installed, if you use Xubuntu 14.04 /usr/bin/qemu-system-arm
- insert the Qemu parameters we used on the command line in the previous post
- click Run
You can now run Qemu just selecting it
from Run->External Tools.
In case you have a real target you can
use External Tools to run OpenOCD.
