怎么在FX2LP上创建一个FPGA接口

里奇
请查看以下网站中提到的“变体”：

你使用的是哪一种变体？
谢谢

    Which variant are you using?
    Thanks

我使用的是XTEX模块1.11C，LX25带有实验板1.2。
我试着运行例子（循环回，Streamin），就像你在AN61345论文中描述的那样。
所有的工作都很好，但是传输中的大部分失败了以下错误：
批量运输
传输中的批量错误失败：997
那个错误意味着什么？
我已经注册了ZETEX VID和PID在CysB.IF中。
然后通过USB将SLav.HEX下载到RAM中。
之后，我用Xilinx平台电缆USB II和冲击工具下载了比特流。
批量输出工作良好，但传输中的批量总是失败。
在CyBoad中，FX2作为从FX2出现，可以吗？
端点2和6被配置为：
终点；
类型=“散装”
方向=“出”
地址=“02h”
属性=“02h”
MpPKTSIZE =“512”
描述类型=“5”
描述符长度＝“7”
区间＝“0”
&端点& GT；
终点；
类型=“散装”
方向=“in”
地址=“86h”
属性=“02h”
MpPKTSIZE =“512”
描述类型=“5”
描述符长度＝“7”
区间＝“0”
&端点& GT；
在USB数据流应用程序中，端点配置没有选择。

  I'm using the Ztex Module 1.11c with the LX25  with a Experimental Board 1.2. 
              
    I’m trying to run the examples (Loop Back, Streamin) like you described it in the AN61345 paper.
    Everything works fine, but the BULK IN transfer fails with the following error:
                    BULK IN transfer
    BULK IN transfer failed with Error Code:997
     What does that error means?
     
    I have registered the ZETEX VID and PID in the CyUSB.inf.
    Then downloaded the slave.hex to the RAM via USB.

    After that I have downloaded the bit-streams with the XILINX Platform Cable USB II and the impact tool.
     
    BULK OUT works fine, but the BULK IN transfer always fails.

    In the CyConsole the FX2 appears as SLAVE FX2, is that ok?
    Endpoints 2 and 6 are configured:
     
                                                  
                                                                   Type="BULK"
                                                                   Direction="OUT"
                                                                   Address="02h"
                                                                   Attributes="02h"
                                                                   MaxPktSize="512"
                                                                   DescriptorType="5"
                                                                   DescriptorLength="7"
                                                                   Interval="0"
                                                  
     
                                                  
                                                                   Type="BULK"
                                                                   Direction="IN"
                                                                   Address="86h"
                                                                   Attributes="02h"
                                                                   MaxPktSize="512"
                                                                   DescriptorType="5"
                                                                   DescriptorLength="7"
                                                                   Interval="0"
                                                  
     
    In the USB Data Streamer application there is no choice for the endpoint configuration.

你好，
错误代码997引用I/O等待重叠到http://MSDN。微软/CON/EN /库/ Windows /桌面/MS68 1388（V= V.85）。正如我之前告诉你们的，下一步应该是控制和数据线探测。由于FX2LP枚举并执行成功传输，我怀疑FPGA。请检查旗线，确认FPGA正在获得EP6空幡的流光示例。-普吉

   Hi,
     
         [size=11.333333015441895px]The error code 997 refers I/O pending for the overlapped to      http://msdn.microsoft.com/en-us/library/windows/desktop/ms681388(v=vs.85).aspx     [size=11.333333015441895px].             
            As I told you earlier the next step should be control and data line probing. Since FX2LP enumerates and performs OUT transfers successfully I suspect FPGA. Please probe the FLAG lines and confirm FPGA is getting EP6 empty flag in the streamer example.
