NIOS II Eclipse - Unable to create project

I am new to NIOS. I have build an SOPC system using Quartus 9.1. The system has an on-chip ram. Now, I am using NIOS II - Eclipse platform to build the application. I choose "New NIOS II Application and BSP from template". After adding my SOPC Information file, I selected blank project, but when I try to create the project, it gives the following error.

--- Quote Start ---

Failed to execute: ./create-this-bsp --cpu-name Host_NIOS --no-make

SEVERE: nios2-bsp-create-settings failed.

SEVERE: Tcl script "bsp-set-defaults.tcl " failed: Section ".rodata" has no memory region mapping.

nios2-bsp: nios2-bsp-create-settings failed

--- Quote End ---

Can somebody help me with this? Is this error caused by some problem with my SOPC system or there is some other reason.

P.S. I am using NIOS II EDS 9.1.

Any response is highly appreciated.
