Note to all users: the board has a severe problem with the NOR flash. The part used is specced at 70 ns access time and the time from deassertion of CE or OE to high impedance on data outputs up to 20 ns. It also does not have a WAIT line. Needless to say this is useless on a system that normally runs a 100 MHz bus clock (interestingly most of the time it does make it). The company answered that it is only supposed to be used as a boot device so one doesn't need a fast access time. Well.. just to let you folks know, if anyone googles after NOR flash problems on this board...
