Are you happy with your timing constraints?

I wouldn't expect the fact you're booting from FLASH to be an issue - I'm concerned this is some misdirection and that the problem is elsewhere. Whilst the changes to the design you mention sound trivial enough, they'll change the routing, potentially significantly.

If your Nios is booting from FLASH (I think it is, right? albeit with this new fault) then that should give you some confidence in that interface.

If timing constraints are missing then you were potentially lucky with your original, functioning design.

Cheers,

Alex
