Hi Marek,

I think I had the same problem as you today when I was using my AM29LV128 flash. The device ID made no sense. I found that the code which reads the device ID was assuming that the flash was connected in 16 bit mode. I followed the suggestion in this post:

http://forum.niosforum.com/forum/lofiversi....php/t1841.html (http://forum.niosforum.com/forum/lofiversion/index.php/t1841.html)

and this fixed my problem. The flash ID was then read as 01:7E:12:0 as it should be.
