是照着这个例子做的http://www.**.com/article/08-11/57630s.html
板子上是XCF04S加XC3S400，在chipscope中configure显示错误信息如下：ERROR: Failed reading JTAG Instruction Register.
ERROR: Configuration failed.
看不到ILA核，但是如果用iMPACT下载后在chipscope中就能看到ILA核，但是采集不到信号，一直显示都是waiting for upload……
我怀疑是不是我的下载线有问题，选择“Xilinx platform usb Cable”显示信息如下，哪位大侠知道这是怎么回事吗？
