gregoryw, 

 This message means that programming is failing in the first step, downloading the programming .sof to the board. This programming operation is downloading to the FPGA -- if you have a different JTAG header on your board that you were using for the EPCS chip independently, you might double check to see that the cable is correct.

I can program the EPCS with the JTAG using the flash programmer , and I can also use it to debug on the IDE console when I am using OnChipMemory, so I think the JTAG is OK. Any others ideas ?.

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

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 ???.  heeeeeelp http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif
