问候，
我正在使用Xilinx Spartan 3E入门套件。
我想将配置位文件下载到板载SPI存储器中。
我阅读了一个关于利用picoblaze以及终端程序（HyperTerminal）的pdf文件，通过RS 232电缆与内存建立
通信。
虽然我一直试图解决这个问题，但我总是失败。
所以这是我的问题：
1）从可用的硬件开始：是否可以通过RS 232到USB电缆对SPI进行编程，还是应该更改电缆类型？
2）如果可以使用上面提到的RS 232电缆，它是否仅限于picoblaze，还是可以使用iMPACT对SPI闪存进行编程？
3）如果iMPACT可以对SPI进行编程，在这种情况下，当我将其插入
电路板时，如何检测电缆的存在？4）应该注意的是，我用picoblaze方法尝试了很多次（
在第1点中提到，但没有用。
电缆未被检测到。
非常感谢任何帮助和文档名称。
此致，Mahmoud

tings,
I am using a Xilinx Spartan 3E starter kit. I want to download a configuration bit file to the SPI memory on board. I read a pdf file about making use of the picoblaze as well as a terminal program (HyperTerminal) to establish communication with the memory through an RS 232 cable. Although I have continuously tried to solve this issue, I always failed. So here are my questions:
1) Starting by the available hardware: Is it possible to program the SPI via an RS 232 to USB cable, or should I change the cable type?
2) If the RS 232 cable mentioned above could be used, is it limited only to the picoblaze, or can I program the SPI flash using iMPACT?
3) If iMPACT could program the SPI, in this case, how do I make it detect the presence of the cable when I plug it into the board?
4) It should be noted that I tried a lot of times with the picoblaze method (mentioned in point 1), but no use. The cable is not being detected.
Any help and document names is very much appreciated.
Regards, Mahmoud
