S29GL256P90 with qSys

Hey, I'm trying to interface the `S29GL256P90` which is a Flash device via a NIOS2 system that was created with qSys altera 13.1

here are screen shoots of the configuration:

However when I try to open the Flash with my NIOS 2 code, it returns null.

After an inspection with signal tap, it looks like it's trying to test it but the device does not repone.

any ideas?

the configuration uses Tristate-conduit bridge and generic TriState Controler
