...
1）在使用之前首先应该确认所必须的硬件都已齐备，这主要包括Plus7021开发套件,和一台调试仿真用的PC
2）PC（计算机）
操作系统windows7/10; 需要500G的磁盘空间，且内存8G以上为佳，方便Xilinx FPGA开发软件VIVODO运行。

Hardware platform preparation
1）Before getting started, you should first make sure that the necessary hardware is available. This mainly includes the Plus7021 development kit and a PC for debugging and simulation
2）PC (computer)
Operating system windows7 / 10; requires 500G of disk space, and the memory is more than 8G, which is convenient for the operation of Xilinx FPGA development software VIVODO。
2.7.2 Hardware platform connection
1) The serial port and SWD debugging tool driver are installed as shown below
...
Usually after the Installation of the SP7021 IDE integrated development environment, the debug tool is connected to the USB socket of the computer, and the relevant drivers are automatically installed, as shown in the following illustration
...
Red box 1 indicates that the computer system recognizes the serial port and assigns the serial slogan
COM5 (Note: Due to computer compatibility, the serial slogan varies from computer to computer)
Red box 2 indicates that the computer system recognizes the J-Link device;
Note: Due to computer compatibility, if the above driver can not be installed automatically and correctly,
the driver needs to be updated manually, as follows
...
The red box content is to select the path that drives the installation directory
2) The serial port and SWD debugging interface are connected as shown below
Pay attention to avoid plugging and unplugging when the development board has power. Be sure to turn off the power and connect the plug cable, as shown below

拨码开关1和2都是OFF状态，平台上电后，内置的Bootloader开始加载固化在EMMC程序到DRAM并执行
...
1 Normal mode
Both DIP switches 1 and 2 are OFF. After the platform is powered on, the built-in bootloader starts to load and solidify the EMMC program to DRAM and execute

拨码开关1为ON状态，拨码开关2都是OFF状态，平台上电后，内置的Bootloader开始将检测平台是否外接U盘，若检测到U盘且U盘根目录存在ISPBOOOT.BIN文件，则读取U盘ISPBOOOT.BIN文件并烧录到平台上的EMMC存储器中, 完成代码的固化操作;
Note: U盘格式目前只支持FAT32
...
2 Program burning mode
DIP switch 1 is ON and DIP switch 2 is OFF. After the platform is powered on, the built-in bootloader will start to detect whether the platform is connected to a U disk. Then read the USB disk ISPBOOOT.BIN file and burn it to the EMMC memory on the platform to complete the curing operation of the code;
Note: U disk currently only supports FAT32 format
