I came across the following problems when I used the Flash Programmer to download project to EPCS16 device.

Altera_ForumAny replies on this issue....?? i am getting a similar error too !! have u solved this issue ???
i am using the quartus 12.0 sp1 Nios II 12.0, also tried Nios II 11.0 software build tools too...- Altera_Forum
in quartus you need to set epcs pins as user defined and manualy connect it in pin planner.

@sashawhosaid hey thanks,... thats exactly what i tried yesterday and it worked, but fitter failed repeatedly for multiple pins connected the EPCS outputs...
then had to do the following to compile it rite and the whole thing worked fine.. thanks to all who gave ur valuable help. 1. Make all dual purpose pins as User I/Os in Device settings. 2. Assignments > Device > Device and Pin Option > Configuration > Disable the "Enable input tri-state on active configuration pins in user mode" thanks once again !! :)
