May be it's a configuration problem.

With my EPCS device i can boot both the FPGA configuration and Nios II software.

I'm using the Quartus 15.0, When i add the EPCS controller, the DATA, DCLK, ASDI, and nCS signals are not exported to Nios entity.To add the EPCS controller i have two choice, altera serial flash controller or legacy epcs/epcqx1 flash controller, i took the first one, it's right ?. In device and pin options, I configured DCLK & nCEO as as as compiler, ASDI & cCS as compiler configured, if not I can't boot from the Flash.

Hope that help to understand my problem.

Best regards
