Android : Couldn't debug c++ code of NDK using GDB and Eclipse (OS - Windows 7)

When I'm trying to debug hello-neon example app. But when press F11 (debug) I see the error below (but the app launches and works):

warning: while parsing target description (at line 1): Target description specified unknown architecture "i386" warning: Could not load XML target description; ignoring Could not AssignProcessToObject

Comment: I'm using Item Atom Phone.

How to fix it?
