2.7.1 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
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
The serial port and SWD debugging interface are connected as shown below
2.7.3 Hardware platform working mode setting
2.7.3.1 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
2.7.3.2 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
