Hi and thx for your answer

Yes I have the full license. Have tryed beginning from the start once again. But it still has this error.

The memtest program can just fine write/read to the flash(can see it has reset the 0x2000 adr). So the .sof file must be ok.

The flash programmer also begins just fine and it looks like the USB blaster is loading the code(it's LED lights up). Then at the end it says it can syncronice with target.

Is it because I need the startup code in the CPLD that will load the .sof image into the SRAM of the cyclone??? The cyclone cannot boot up on it's own right???

Sorry but I am quit new at this HW design. Usually I just write SW http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/ohmy.gif )
