Problem reading flash memory

Hi guys, we're working on the altera DE2 board with a 4Mbyte Flash memory (S29AL032D model04). We loaded with the altera control panel

address: 196608

wdata: aa (10101010)

we controlled the correct storage of data in the memory with control panel.

Then we builded up a FSM in VHDL to read this data from Flash (code attached). To display the 8 bits of data we light on 8 red leds.

Downloanding the program on the FPGA the results is that all the 8 red leds

are on. We can't understand why...

Can someone help us ???

Thanks
