Spartan 3AN入门套件的并行闪存问题

所以我花了最近3天的时间撞击Spartan 3AN入门套件中的并行闪光灯。
（EDK 10.1.01）如果我使用BSB创建一个只有flash，microblaze，ddr2 sdram和一些板载缓存的板，请将bitgen下载到芯片，并使用我得到的程序闪存项：
连接到“mb”目标。
id = 0在TCP端口号1234done处启动“mb”目标（id = 0）的GDB服务器。*打开要编程的图像文件...完成。*设置Flashwriter源以进行编译... *在闪存上执行CFI查询
part（s）... *错误：Flashwriter应用报告错误：无法使用CFI成功查询目标部件布局！* Flashwriter终止！完成！
当我尝试使用Spartan 3A的微型闪存编程器参考设计时，我得到同样的东西。
我使用petalogix的u-boot遇到了类似的问题（无法通过CFI检测闪存）。
当我将闪存接口修改为8位宽，并使用u-boot时，我得到一些接近合理的东西（在底部发布），但是会指示闪存地址可以正确移位两位。
我准备上显微镜，看看这是不是一块屁股板，但我想知道是否有人使用Spartan 3AN入门套件进行并行闪存？
u-boot输出：

以下为原文

So I have spent the last 3 days banging my head against the parallel flash in the Spartan 3AN starter kit.  (EDK 10.1.01) If I use BSB to create a board with just the flash, microblaze, ddr2 sdram, and some onboard cache, download the bitgen to the chip, and use the program flash memory item I get:

Connected to "mb" target. id = 0
Starting GDB server for "mb" target (id = 0) at TCP port no 1234
done.
* Opening image file to be programmed...done.
* Setting up Flashwriter sources for compilation...
* Performing CFI Query on the flash part(s)...
* ERROR: Flashwriter application reported an error: Unable to successfully query target part layout using CFI!
* Flashwriter terminating !
Done!

And I get the same thing when I try the microblaze Flash programmer reference design for the Spartan 3A.

I get a similar problem using u-boot from petalogix (failure to detect the flash through CFI).  When I modified the flash interface to be 8 bits wide, and use u-boot I get something that is close to sensible (posted at the bottom) but would indicate that the flash addresses are all right shifted two bits.  I'm about to go get on a microscope and see if this is a bum board, but I was wondering if anyone had gotten the parallel flash working with the Spartan 3AN starter kit?
