1.建立一个工程。

硬件设计

2.IP integrator -> create block desgin;Run Block Automation.

3.add IP -> AXI GPIO;ritht-click -> Costomize Blocking or double left-click，gpio 8bits leds；

3. Run Connection Automation -> select all.

4.file -> save

硬件处理

5.Tools -> Validate Design

6.right-click -> Generate Output Products;right-click -> Create HDL Wapper;

7.Generate Bitstream.

8.File -> Export Hardware;include bitstream.

9. File -> Launch SDK

接下来在SDK中写软件

10. File -> New -> App Project.

11.Next -> Hello World -> finish.

12. open -> resouce -> helloworld.c

13.写代码

 #include <stdio.h>

 #include "platform.h"

 #include "xil_printf.h"

 #include "xparameters.h"

 #include "xgpio.h"

 #define LED_DELAY 10000000

 void led_delay()    //times delay

 {

     u32 i;

     for(i=;i<=LED_DELAY;i++);

 }

 int main()

 {

     init_platform();

     u32 cnt,m;

     //loop forever

     while(){

         for(m=;m<=;m++){

             Xil_Out32(XPAR_AXI_GPIO_0_BASEADDR, 0x01<<m);

             led_delay();

             if(m==){

                 printf("Hello World! %ld:SUCESS!\n\r",cnt++);

             }

         }

     }

     cleanup_platform();

     return ;

 }

14.Save.

控制出现 build finished 就编译好了。

下载与调试

15.连接zedboard与pc。两根microUSB，一根是PROG，JTAG；一根是USB转串口。上电！

16.Xlinx -> Program FPGA

17.Run -> run configurations -> run

Done！

此时板上led开始闪烁，控制台也开始打印输出。

finished！
