Hi,
As you said, "i have selected the HS08 Beestack codebase 3.1.1 and set active and select the hardware MC13213." I think you don't need select hardware when you choose the code base.
After you choose the HS08 BeeStatck codebase 3.1.1, you can open dialog use File->New Project, then choose one application model.

After you settle down project directory and type Project name, you can configure you project to select MC13213 platform and other Zigbee configurations.

I think you'd better read Freescale Beekit user guide first. You'll find beekit is a powerful & useful tools.
