wrong device ID by auto-decect in Quartus2

Question

Hi everybody!

I'm Trying to program EP4SGX180 device in JTAG inderect mode,but I got the error as follows:

Error: Can't configure device. Expected JTAG ID code 0x024210DD for device 1,but found JTAG ID code 0x024020DD.

Then I open programmer tool and click "auto-detect" instruction.The device detected by Quartus2 unexpectedly is ER4SGX360(its ID CODE just is 0x024020DD).

I ensure the various voltage up to the specification and the USB-Blaster cable OK. I want to know what reason should cause above mentioned phenomenon.

Thanks in advance!

You may have assigned a different device in Quartus compared to what you are programming:

It's rather unlikely, that the JTAG interface transmits two ID bits continuously wrong, although possible. The said numbers are correct according to quartus/bin/pgm_parts.txt, the ID list used by Quartus.

Did you try to program the device as GX360?

P.S.: You have been talking about JTAG indirect programming. The problem should happen in all JTAG accesses? Does it?
