How to connect DM6467 to 64MB NOR

Other Parts Discussed in Thread: OMAP-L138

We need to connect the 6467 to a 64MB NOR, 16-bit bus.  So we need to use chip selects CS2 and CS3.  A couple months ago, I think I saw a wiki page that showed how to do this, but I can no longer find this wiki.  Can someone direct me to it or give me some more info on how to do it.

    Perhaps you mean this wiki article from OMAP-L138? Though it is not for DM6467 it largely applies still, you could do the same basic thing with DM6467 by spanning the chip selects.

    The alternative would be a GPIO based paging scheme, where you simply tie the highest address bit of the NOR to a GPIO and toggle it in software to switch between halves of the memory.
