Hm... how can I tell if it does? The driver reports "AMD Standard command set", so it probably does. > with Nios II.

Well, I see that no real 64 bit accesses are used, so I think we will here see two 32 bit accesses to get the full 64 bit data, and probably the same thin happens. > Not sure if this is similar to your situation ... but it was a real > pain-in-the-butt to finally understand what was happening in my > situation. And how did you fix it?
