我做过DSP5509A和FPGA的通信 用的是EMIF接口
只需要接CS，XWE,XRD就可以啦 不知你是怎么接的
参考一下代码 多多找些XINTF相关的资料
Xintf初始化：
// All Zones:
// Timing for all zones based on XTIMCLK = SYSCLKOUT/2
XintfRegs.XINTCNF2.bit.XTIMCLK = 1; // XTIMCLK = SYSCLKOUT/2
XintfRegs.XINTCNF2.bit.CLKOFF = 1; // DISABLE XCLKOUT
XintfRegs.XINTCNF2.bit.WRBUFF = 0; // NO WRITE BUFFER
XintfRegs.XINTCNF2.bit.CLKMODE = 1; // XCLKOUT = XTIMCLK/2
// Zone 0
// Ignore XREADY for Zone 1 accesses
// Change read access lead/active/trail timing
XintfRegs.XTIMING0.bit.USEREADY = 0;
XintfRegs.XTIMING0.bit.XSIZE = 3; // ALWAYS WRITE TO 11BIT
XintfRegs.XTIMING0.bit.XWRACTIVE = 3;
XintfRegs.XTIMING0.bit.XWRTRAIL=7;
XintfRegs.XTIMING0.bit.XWRLEAD=3;
XintfRegs.XTIMING0.bit.XRDLEAD = 3;
XintfRegs.XTIMING0.bit.XRDACTIVE =7;
XintfRegs.XTIMING0.bit.XRDTRAIL = 3;
// Double lead/active/trial timing for Zone 1
XintfRegs.XTIMING0.bit.X2TIMING=1;
