I still get the same problem, I use Stratix IV board with xxxx.sof (on device EP4SE530H35C2ES).

I use USB Blaster cable with passive serial mode.

If I use auto detect, it comes out a selection window (EP4SE530 and EP4SE530ES), I pick the first one, it comes out two devices (EP4SE530 and EPM2210). Then I add file xxxx.sof, it add a new device EP4SE530H35C2ES. I press start, it quickly print out a message

Error (209031): Device chain in Chain Description File does not match physical device chain -- expected 3 device(s) but found 2 device(s).

I do not know how to continue!

I am new to altera. Please help me up.

Thank you.
