hello jim,

are you using the flash in 8 bit mode? if yes take a look at: http://forum.niosforum.com/forum/index.php?showtopic=455 (http://forum.niosforum.com/forum/index.php?showtopic=455)

Hi niosIIuser,

I am using a 16 bit Flash.

In SOPC Builder, for the CFI Flash Memory Device I selected:

AMD29LV128M (WORD Mode) Add Width: 23 bits, Data Width: 16 bits

I looked at the Post you referenced and it made me question how I connected the

Address lines. I shifted the Address lines by 1, that is address bit 1 from

the ext_flash_bridge_address is connected to my Flash Device Address bit 0.

Thanks for the reply.

Jim
