Compiling and Running error on the android vim3!

1 Could vim3 android with galcore6462 connect with wired network not only wireless network?
2 I want to send ssh cmd from host pc/server to the android vim3 not through adb cmd.
3 Could I compile the c++ project directly on the android vim3 board without cross-compiling ?
Is there any method or tools could support the above two feature?
4 Maybe we could use cmake/ ndk toolchains on the android vim3 , is it right ?
