I have a Wandboard (with an ARMv7 processor) and I bought recently an Arduino Due.
I wanted to connect my board with Arduino, and work with the IDE on it.
Unfortunately the source isn’t configured to support such architecture, so I tried to modify it.
Adding this line in the build.xml and I replacing librxtxSerial.so with an ARM version, it compiles, and the GUI works:
<condition property="platform" value="linux32"><os family="unix" arch="arm" /></condition>
Problem: I noticed that the CodeSourcery compiler for SAM3X is pre-compiled for x86/64, so i can’t compile sketches on my machine with it.
I tried to modify hardware/arduino/sam/platform.txt linking the arm-linux-gnueabi default compiler installed on the device.
I managed to get something, but it doesn’t work.
It seems to be an incompatibility between architectures in an AR file in the source.

Can you help?
