Porting from Legacy tools to Eclipse Environment

Hello Everyone,

I am a new user of nios-II ide and also Eclipse IDE, I was using nios-ii legacy tools to develop application for the design.

Now I want to port my design on the Eclipse Platform, but tool is asking for the BSP file. Can anyone provide me proper reference for the usage of the Nios-II Tools with eclipse environment.

Thanks and Regards,

Vijay K
