DE2-115 schematics don't show EPCS pins

I'm trying to get my hardware/software nios project into the EPCS64 device on the DE2-115 board. It sounds like I need a EPCS controller in my nios project, but when it exports the signals for the c...

I've still got a problem ... for some reason I can't bootload the nios code.

To debug this issue, start off by simplifying things, so that you can isolate the issue.

For example, does the FPGA load correctly? You could add a JTAG-to-Avalon-MM bridge to your design to confirm that the design is correctly loading from EPCS. Once you have confirmed that, you will know for sure that the issue is related to the NIOS II processor not booting.

I don't use NIOS II, so cannot offer much help. If I did, the first thing I would confirm is that it works in simulation.
