Yep, I'm using the correct device n the megafunction (epcs16). It's failing in the actual hardware where as I mentioned earlier the nCS behaves as though it's being inverted. The traces below show the operation during a read through the asmi function. The signals from top to bottom are conf_done, asdi, nCS, data, dclk.
