Custom Flash is not supported in Altera Qsys 12.0

sorry if I confused you:

You don't need to include the tristate_conduit_pin_sharer in your system if the the hardware connections to the CFI Flash are not shared

with other chips in the system (which is the case for the DE115). You can connect the generic_tristate_controller directly to the tristate conduit bridge (tcs to tcm).

I have build several systems that work this way. The CFI will work only if you set the right parameters (size, adress width, signal polarities etc.)

Just look at the provided demo projects, you have to scroll down in the generic_tristate_controller window to see them all. There is also a right pane where you can choose presets.

I have had no problems flashing the cfi, your configuration seems ok to me. Have a look at the output from the Nios2 flasher to see if it has included the boot loader.
