Unable to open flash-device

An update : when I run the memtest from the SRAM and I try to test my flash, I get the following message :

it seems that my AMD flash can not be reconized. So I m wondering if there is a list somewhere in the ALTERA sources that tells how to reconize if a flash is an AMD an INTEL or something else ???.
