EP3C16建立NIOS II软核，epcs-flash引脚设置后Quartus编译报错，是啥问题？

以前使用EP2C8建立NIOS II软核，epcs-flash引脚不需要设置。

Can't place multiple pins assigned to pin location Pin_12 (IOPAD_X0_Y25_N7)

把双功能pin统统设为regular I/O pin。

搞定，谢谢了。

怎么搞定的，能否透露，我也是用EP3C16,双功能脚也设成了regular I/O pin，综合时没有错误，但是烧写时报错：
No EPCS layout data - looking for section [EPCS-FF]
Unable to use EPCS device

我遇到的问题同四楼，能否指教一下，谢谢。

请问下，你的问题解决了吗，我也遇到跟你一样的问题，一样的报错，不知道是什么问题。
