Have you verified that your FPGA configuration is running. Blink an LED or pulse a GPIO pin. This is just to verify that the FPGA configured properly. You didn't mention if the demo project you started from uses external RAM. If you haven't already, try compiling from source a demo project that uses the external ram and verify that it works. Next, run memory test software on that system to ensure that hardware is working.
Starting from a demo project that you compiled, add and remove components one at a time. Each time run the memory test to verify that memory isn't broken. Save a copy of every step so you can go back if necessary. Keep going until you find a change that breaks external memory. That will give you a starting point for debugging.

Hi Galfonz,
Thanks for your reply. The Demo project uses an external RAM. I took the Demo project template of Qsys and added the extra component of my project into it and removed some unnecessary component from the Demo project template like the temperature sensor IP core. You also mentioned about memory test, could you please let me know how to do this memory test ?
Thanks,
