1、软件版本vivado202001。
2、其中程序的源文件都是拷贝过来的只是稍作修改，对其中的操作步骤做细化分析，参考文档UG585
https://blog.csdn.net/weixin_41922484/article/details/104037513
3、串口打印FSBL中启动信息。
只需要在以下位置的的fsbl_debug.h中，添加一个宏定义即可。
#define FSBL_DEBUG_INFO
4、新建两个app
hello_test1.c
#include
#include "platform.h"
#include "xil_printf.h"
#include "xil_io.h"
#include "sleep.h"
#define PSS_RST_CTRL_REG 0xF8000200 //PSS_RST_CTRL寄存器，绝对地址，
#define SLCR_UNLOCK_ADDR 0xF8000008 //SLCR_UNLOCK寄存器，绝对地址，
#define UNLOCK_KEY 0xDF0D //使能码
#define PSS_RST_MASK 0x01 //复位码
void PsSoftwareReset(void)
{
Xil_Out32(SLCR_UNLOCK_ADDR, UNLOCK_KEY); //写使能
Xil_Out32(PSS_RST_CTRL_REG, PSS_RST_MASK); //复位
}
#define XDCFG_MULTIBOOT_ADDR_OFFSET_REG 0xF800702C //MULTIBOOT寄存器，绝对地址，
#define XDCFG_UNLOCK_OFFSET_ADDR 0xF8007034 //XDCFG_UNLOCK_寄存器，绝对地址，
#define UNLOCK_XDCFG_KEY 0x757BDF0D //使能码
#define APP1_LOCATION 0
#define APP2_LOCATION 128
void ModifyMultiBoot(void)
{
Xil_Out32(XDCFG_UNLOCK_OFFSET_ADDR , UNLOCK_XDCFG_KEY ); //写使能
Xil_Out32(XDCFG_MULTIBOOT_ADDR_OFFSET_REG , APP2_LOCATION ); //更改MULTIBOOT
}
int main()
{
init_platform();
print("111111111111111111111111111111111111111\r\n");
sleep(5);
ModifyMultiBoot();
PsSoftwareReset();
cleanup_platform();
return 0;
}
hello_test2.c
#include
#include "platform.h"
#include "xil_printf.h"
#include "xil_io.h"
#include "sleep.h"
#define PSS_RST_CTRL_REG 0xF8000200 //PSS_RST_CTRL寄存器，绝对地址，

#define PSS_RST_MASK 0x01 //复位码
void PsSoftwareReset(void)

#define XDCFG_UNLOCK_OFFSET_ADDR 0xF8007034 //XDCFG_UNLOCK_寄存器，绝对地址，
#define UNLOCK_XDCFG_KEY 0x757BDF0D //使能码
#define APP1_LOCATION 0
#define APP2_LOCATION 128
void ModifyMultiBoot(void)
{
Xil_Out32(XDCFG_UNLOCK_OFFSET_ADDR , UNLOCK_XDCFG_KEY ); //写使能
Xil_Out32(XDCFG_MULTIBOOT_ADDR_OFFSET_REG , APP2_LOCATION ); //更改MULTIBOOT
}
int main()
{
init_platform();
print("222222222222222222222222222222222\r\n");
sleep(5);
ModifyMultiBoot();
PsSoftwareReset();
cleanup_platform();
return 0;
}
5、分别生成bin文件，且需要注意生成的bin文件大小，因为是分段烧写flash，第一个bin与第二个bin的间隔要比第一个bin的文件要大，且间隔为32KB的整数倍，此次实验中，生成的bin都是2.2MB，所以把第二个的bin起始地址设置为128*32KB。
6、在JTAG模式下烧写FLASH
7、在QSPI模式下启动
