为什么在JTAG里面查不出有PROM器件呢？？困惑了

只看该作者 · 2011-7-29 16:41

各位高手，我的板子上用了Spartan 3A的xc3s400和Prom型号为xcf04sv0g20c
现在JTAG连接时，xc3s400器件能找到，但是xcf04sv0g20c的器件找不到，然后程序也下不到FPGA里面，我使用的是xilinx91i编译器，具体错误如下：
Attempting to identify devices in the boundary-scan chain configuration...// *** BATCH CMD : Identify
PROGRESS_START - Starting Operation.

高手们，帮忙看下，到底是哪出错了啊？
