Cross_Compilation for NanoPi NEO

Moderators: chensy, FATechsupport

We are using NanoPi NEO in our application. Our application can able to run on ubuntu16.04(x86_64) desktop system, but we wanted to run it on NanoPi NEO(armv7l). Can any one please tell us, How to do cross compile in ubuntu16.04 system to run our application on NanoPI NEO?

You need to provide more info. What is the OS of the target nanopi neo ? Ubuntu or other ?

There are two schools:

1) use the gcc for ARM https://packages.ubuntu.com/fr/trusty/g ... ux-gnueabi from your distribution or you can find prebuilt here http://downloads.yoctoproject.org/relea ... in/x86_64/. The problem is this toolchain is not specific to nanopi neo but it is quite simple to install.

2) generate your own toolchain specifically for nanopi neo. All the libs will be optimized for the target processor but this is quite difficult in general. My target OS is not ubuntu but yocto linux, consequently the generation of the optimized cross toolchain is straightforward with bitbake <image> -c populate_sdk
