Hi!
Yesterday I get my first build of a NanoPi port of pi4j (http://pi4j.com/) running. A simple test with a double color led on a NanoPi M1 works fine. Actually I am going to adapt the board specific code. Hence some questions are open.
- Is there a simple way to differ NanoPi Boards by SW (NanoPi M1, Neo and Air) to set the correct board?
- Memory size of the board
The Raspberry code uses the revision string of /proc/cpuinfo to retrieve this informations. But this info is PI specific. Any idea how to get this info? Using C is not a problem - pi4j is a mix of Java and native libraries.

P.S: Java Example File - don't be confused - the extension bsh stands for bean shell, scripting for Java - quick testing without compiling

I got my NanoPi Neo Air last week. But in my box there was no IPX antenna included. Additional pin headers availbale - but not antenna.
According the item list an antenna should be included:

The antenna should be inside the bag of the pin headers?

Hi!
When I try to use WinSCP in Windows - which works for everything normally, using root and 1234, I see it try to login - for an instant I see it has succeeded and then instead of getting the normal window full of files in the root directory - WinSCP just goes back to the login dialog with no pane of files coming up... as if it had failed to login but but clearly it is not failing as the view is very different if I deliberately put the wrong password in.
I think the problem is caused by the fact, that the first login on the system causes a request changing the root passwort. Please login on the NEON via putty. Change the root passwort. This should solve your problem.

Thanks! This fix solved the problem!

FriendlyArm released a NanoPI NEO specific heat sink:
http://www.friendlyarm.com/index.php?route=product/product&path=82&product_id=134
I am the owner of NanoPI NEO using the modified NanoPI M1 Armbian image of this thread.
I am not a expert of SBC design. But this board gets very hot. The sink has the same size like the SBC! Has the SBC a design problem, e.g. power supply? Or the CPU is so powerful and you must fix the heat problem by a approbiate heat sink or by software.

There is an article from the c't magazine about this boad. Also mentioned the Armbian OS as an alternative OS to FA the ubuntu core.
