JTAG ID error

[Altera_Forum]

Hi, there 

 I tried to implement Video-over-IP reference design on the Cyclone II dev kit. The Altera website said this reference design support Cyclone II series dev kit, and my one is EP2C35. But, when I downloaded the hardware image on to the dev KIT, error occurs, and here is the error information:  Error: Can't configure device. Expected JTAG ID code 0x020E30DD for device 1, but found JTAG ID code 0x020B40DD. Error: Operation failed  I tried every possible port, and even when I tried to do factory recovery config, the same error still happen. Could anyone tell me what happened? And how should I fix this error? Thanks. :confused:

The JTAG ID clarifies, that the image is dedicated to Stratix II GX90. It can't run on Cyclone and must be recompiled.

In the folder, there are two sof file. One is the demo_2sgx, another is demo_4sgx. The manual said the demo_2sgx corresponds to the cyclone edition while the demo_4sgx corresponds to the Stratix series. I tried the demo_2sgx file. Anyway, I will recompile it and report the status. Thanks.

I recompiled it. Yes, it should be a different .sof file. Now the hardware image works. However, when I download the software image .elf file on the board. It shows the following error: 

 There are no Nios II CPUs with debug modules available which match the values specified. Please check that your PLD is correctly configured, downloading a new SOF file if necessary.  And when I tried to follow the steps on the Nios II Development Kit Getting Started User Guide, the same problem occurs when I Downloading and run the Executable Code to the Nios Development Board. Could anyone give me a hint how to solve it? Since the downloading for the hardware image is ok, I assume the JTAG cable should be fine. Am I right?
