The FPGA chip on the development board is configured as an AE250
MCU using Gowin Programmer in PC, after the Debug Cable is connected,
you can perform the embedded program development and debugging with
AndeSight RDS v311 software.
1.2 Preparations
Before using Gowin FPGA and AE250 for development and debugging,
the following tools need to be prepared:
1. Gowin GW2A series of FPGA development board.
2. Gowin Software installation package for configuring and downloading
the FPGA chip.
3. AndeSight RDS v311 installation package for developing and
debugging the embedded program.
4. Debug Cable is used for downloading and debugging the embedded
program, and the default is AICE-MINI+; users need to purchase it by
themselves.
Note！
If it needs to output information through UART, a UART to USB cable is needed.
Other peripherals to be used are required.

1.3 Developing and Debugging Steps
IPUG546-1.1E

1.3 Developing and Debugging Steps
The basic steps for developing and debugging RISC-V AE250 MCU
based on the GW2A-55C development board are as follows:
1. Install softwares: Gowin Software is used to configure and generate
AE250 RTL design and generate the Bitstream file of the design;
AndeSight RDS v311 software is used to develop and debug
embedded programs; other softwares and drivers for debugging are
also required.
2. Configure the power supply and download cable of the development
board. The Bitstream file of AE250_chip is downloaded to the FPGA
chip on the development board using Gowin Programmer, and AE250
is running on the development board.
3. Open RDS software to create a new embedded project or open an
existing project for encoding, compiling and other operations. Connect
the Debug Cable used for AE250 debugging, download the project
compilation result to the instruction memory (ILM) in AE250, and start
debugging on the chip.
4. During debugging, you can use UART to USB cable to connect the
UART interface of AE250 to PC, use the built-in serial terminal in RDS
to operate the input and output operations. You can use GPIO to
connect to LED indicators, keys, or external pins for input/output
operations; I2C, SPI, Ethernet, and other peripherals can also be
selected to use.
5. AE250 can connect to a Flash via SPI, download the compilation result
of embedded program to Flash using Gowin Programmer; when the
chip is powered on, AE250 will automatically read the embedded
program in SPI Flash and start. You can reuse the Flash that saves the
FPGA Bitstream; some can save the FPGA bitstream, and others can
save the compilation results of embedded programs. This is a practical
and economical method.
You can see chapter 2 Debug Cable Connection Instructions, chapter
3 Use Instructions for RDS, and chapter 4 Reference Design for detailed
steps.
2 Debug Cable Connection Instructions
IPUG546-1.1E
4(17)
2Debug Cable Connection Instructions
RDS + AE250 use AICE-MINI+ debug cable by default; the exterior is
shown at left in Figure 2-1, and the pins are shown at right in Figure 2-1. It
is a 12-pin interface. It is should be noted that pin 1 is blank in the figure.
When the cable is correctly connected and RDS is opened, the red LED
light marked with yellow box in the figure will go out.
Figure 2-1 AICE-MINI+ Debug Cable and its Pins
The pin definition of AICE-MINI+ debug cable is as shown in Table 2-1.
It should be noted that Pin 1 is defined as No Connection (NC),
corresponding to the blank one. VREF needs to connect a 3.3V power pin,
and GND only needs to connect the pin 3 or the pin 5.
