FreeRtos on Microblaze inside Zynq

I am using Microblaze on Zynq FPGA using Zedboard. I successfully design my hardware and also successfully test the bare metal application on microblaze. Now, I am trying to use FreeRtos on Microblaze. I download the freertos port from (http://www.freertos.org/Integrating-FreeRTOS-Library-and-Project-Creatio...) and create a BSP as given on the website. After generating the BSP, when I wanted to create application using freertos, in the dialog box, no freertos application visible to me. What, I did, I just create an application simple helloworld (bare metal) but I include the freertos BSP. Later on, I copied the freertos_application source code and pasted into the main.c of my helloworld application. When I run the application, I got the following error: Note(I am using BRAM (64kB I and 64KB Data) within microblaze hardware). Although the program is not too big, still I am getting error. I also checked with BSP settings (GUI), where the Stack Size=120 B and HeapSize Value= 1024, default=65535. I am really stuck at this point. Please help me to sort out this.
