Honored ContributorOk i have observed some thing... but still put me into dead end.
In the Qsys, the EPCS controller has not been exported. The component is not accepting the option to use dedicated AS pins. It says its not supported. So i exported the pins and then assigned the corresponding pin numbers. I have also cross checked that the pins are marked as "Regular I/Os" in the dual purpose pins tab in device settings. still i am getting error in fitting....
