NanoPI Neo Air

Hi 

I am considering to use NanoPI Neo Air for my next embeded project. 
I need some help for my development set up:
1. Plan to use Eclipse for C/C++ 
2. Develop the code on Linux / Ubuntu in Eclipse IDE 
3. And then cross compile for H3 and deploy only the executables onto
NanoPi Neo Air 

My questions:
1. I have seen some set up as descripbed above. Where do I get cross
compiler for H3?
2. How can I make my project executable secured in the flash of NanoPi
NeoAir? 
3. Also planning to use HD camera with the Neo Air for video, is there any
video camera that I can use with NeoAir?

thanks 
Silas

Hi,
    1. Visit this site [https://pan.baidu.com/s/1dF7HL0P download link],
enter the "toolchain" directory, download the cross compiler
"gcc-linaro-arm.tar.xz" and copy it to the "lichee/brandy/toochain/"
directory.

     2.You can CAMB500B camera.

thank you!
