MYIR-ZYNQ7000系列-zturn教程(20)：在zynq双核上跑不同的工程
开发板环境：vivado 2017.4 ，开发板型号xc7z020clg400-1，这里主要在两个不同的cpu上跑不同的程序，cpu0跑hello_world工程
cpu1跑一个led不断闪烁的程序，并且两个程序能同时运行。

Step1 新建一个vivado 工程
调用一个zynq核
然后按照下面的截图进行设置
我这里配置了UART和SD卡以及gpio_mio，并且设置DDR的型号以及SDIO频率（不同的开发板有所差异请自行调整）
自动连线后如下图所示
Step2 综合、生成顶层文件，生成bit文件
综合
生成顶层文件
生成bit文件
Step3 导出硬件配置，打开SDK
Step4 新建fsbl
Step5 新建工程app_cpu0
使用hello_world模板
工程新建完成后如下图所示
Step6 新建工程app_cpu1_bsp
我们将Value这部分-mcpu=cortex-a9 -mfpu=vfpv3 -mfloat-abi=hard -nostartfiles -Wall -Wextra改为-mcpu=cortex-a9 -mfpu=vfpv3 -mfloat-abi=hard -nostartfiles -Wall -Wextra -DUSE_AMP=1
如下图所示
生成完成后如下图所示
Step7 新建工程app_cpu1
选择hello_world模板
新建完成后如下图所示
Step8 添加cpu0和cpu1主程序
cpu0主程序，我这里将hello_world工程改为每隔一秒打印一次，并且一直运行

#include
#include "platform.h"

int main()
{
init_platform();
while(1)
{
print("Hello World\n\r");
sleep(1);
}
cleanup_platform();
return 0;
}
这里是cpu1的主程序
这里主要是对gpio_mio0给0和1控制led灯不断的闪烁

#include
#include "platform.h"
#include "xil_printf.h"
#include "sleep.h"
#define Base_Address 0xE000A000
int main()
{
Xil_Out32(Base_Address + 0x00000204 , 0xFFFFFFFF);
Xil_Out32(Base_Address + 0x00000208 , 0x00000001);
while(1)
{
Xil_Out32(Base_Address + 0x00000000 , 0x00000001);
sleep(1);
Xil_Out32(Base_Address + 0x00000000 , 0x00000000);
sleep(1);
}
}
Step9 更改cpu1的ddr地址（cpu0默认不变）
点击这个lscript.ld文件
将地址改为红色方框中一样的就可以了
Step10 再在fsbl的main.c文件中添加cpu1启动程序
在fsbl下找到这个main.c文件并且打开
然后在main函数前面添加这个红色方框的程序
#define sev() __asm__("sev")
#define CPU1STARTADR 0xFFFFFFF0
#define CPU1STARTMEM 0x02000000
void StartCpu1(void)
{
#if 1
fsbl_printf(DEBUG_GENERAL,"FSBL: Write the address of the application for CPU 1 to 0xFFFFFFF0\n\r");
Xil_Out32(CPU1STARTADR, CPU1STARTMEM);
dmb(); //waits until write has finished
fsbl_printf(DEBUG_GENERAL,"FSBL: Execute the SEV instruction to cause CPU 1 to wake up and jump to the application\n\r");
sev();
#endif
}
再在loadBootImage（）下添加这个StartCpu1()；
StartCpu1(); /*add starting cpu1*/Step11 生成BOOT.bin文件并放到开发板上运行
在你新建的工程目录下新建一个BOOT文件夹，如下图所示
第一步将fsbl.elf文件复制到BOOT文件里
第二步将bit文件复制到BOOT文件里
第三步将cpu0.elf文件复制到BOOT文件里
第四步将cpu1.elf文件复制到BOOT文件里
xilinx-->Create Boot Image
点击这个Browse选择这个BOOT文件路径
找到BOOT文件，点击保存
如下图所示
点击Add将BOOT文件夹里的四个文件都添加进去
点击Browes
请务必按照截图中数字顺序添加
点击 Create Image 生成BOOT.bin文件
将这个生成的BOOT.bin文件拷贝到TF卡里运行
cpu0串口不断打印hello_world
cpu1工程的这个D29接的是mio0会不停的闪烁
