Flash CFI in SoPC Builder

Hi All,

I am trying to connect 22x8 bit (4MByte) flash memory on DE2 board via flash cfi controller. If I connect it to the Avalon tri-state bridge I got the following error: "signal tri_state master and signal cfi_flash must have the same data with". What should I do to fix it?

Please check the attachment.

Thanks!
