Insert the Micro SD card into the SD adapter and plug it into the computer. We will format the SD card and then copy the audio and picture files in the Other directory on the COPY CD in the SD card. The picture directory contains the 1024x768 image data we want to display on the VGA monitor.
Use the WINHEXPDFtool under the TOOL directory to open the SD card and look at the Sec address where the picture is located.
After opening the SD card, you can see the image data in the Picture\ VGA directory of the root directory of the SD card 1.bin The Sec address of the SD card is 213208.

|
|
|
|
Note: The address of this image on the SD card may differ |
|
|
|
|
|
|
|
depending on the model of the SD card. It is best to use Winhex |
|
|
|
before the user to use it. If it is found to be different from ours, the |
|
|
|
user needs to modify the SADDR parameters of the sd read.v |
||
|
program in the DEMO_A project. In addition, there are some types of |
||
|
SD cards. This address shows the SD card's root offset address. |
|
|
|
|
|
|
|
When SADDR is used, it is also necessary to add the address of the |
||
|
root directory. |
|
|
|
Power off the development board, insert the Micro SD card into the |
||
|
SD card slot (U14) of the development board, and connect the VGA |
||
|
port (J4) of the development board to the VGA monitor. The |
|
|
|
|
|
|
|
hardware connection diagram is as follows: |
|
|
|
|
|
|
After the development board is powered up, press the KEY4 key. The
VGA display will show the 1.bin image stored on the SD card. The following figure shows the effect of pressing the KEY4 button VGA display.
4.Software Installation
The next taskPDFis to start installing software. The XILINX FPGA development environment is ISE, and the ISE version we use is 14.7. In addition, if you need to do program simulation users also need to install Modelsim software, we use the Modelsim version 10.1c.Refer to the first and second parts of the "Black Gold Sparten6 Development Board AX309 Verilog Tutorial V3.1.pdf" document in the 09_VERILOG directory for
software installation and cracking.
5.Install the download driver
1. Connect the black USB cable that comes with the development board to the computer's USB port and the other end to the Xilinx USB Cable. After downloading, the download status indicator will light up (green).
|
|
|
2. If the computer is connected to the Internet, the operating system will |
|
automatically download the driver and install it automatically. |
|
|
14 |
|
|
|
|
Waiting for a while will show that the installation is complete. |
|
|
|
|
|
|
At this time, the USB Serial Converter device can already be seen in the device manager, indicating that the Xilinx USB Cable driver has been installed and we can use it normally. The following steps 3 to 8 do not need to be done.
3.If the computer is not connected to the Internet, we need to manually
install the driver. If the operating system is a 64-bit user, click on the install_cable.exe that we provided under the \07 DRIVER\Xilinx USB Cable\ nt64 directory; if the operating system is a 32-bit user, click We provide
install_cable.exe in the \07 DRIVER\Xilinx USB Cable\nt directory.
4. Click "YePDFs" to start the installation
5. Both options, then click Next.
|
|
6. |
|
You will be prompted to unplug the Xilinx USB Cable, then listen to it! |
|
|
|
Unplug the USB cable from the downloader to the computer. |
|
7. |
|
Click the Install button |
|
|
|
|
|
Until the installation is complete.
8. Connect the computer and the downloader again with the USB cable. The computer will show that the driver is successfully installed. The USB
Serial Converter device can be found in Device Manager.
6.DownloaderPDFand board connection
Insert the JTAG cable into the 14-pin connector of theXilinx USB Cable. Pay attention to the direction of the interface. The notch on the socket needs to be aligned
with the bump of the cable. Do not insert it in the opposite direction.
Then, connect the other end of the JTAG cable to the JTAG socket of the development board. Note that the direction is the same as the figure below.
|
|
After the connection is completed, the board is powered up, which means the |
|
downloader's Status LED will turn orange. |
|

7.Verilog program download test
After the above processes are completed, next, we must try whether the AX309 development board can download the program. You must also look forward to it for a long time. Now let's get started.
In the 09_VERILOG directory, we have prepared Verilog tests for you.
The program, each instance is verified on the development board.
Below I willPDFshow you how to do a download test. The program demonstrated here is a running light experiment under the 4_led_test
directory. We enter the 4 led test folder, find the led_test.xise file, and double-click to open the ISE project file.
After entering the ISE14.7 software, we click on the Configure TargetDevice icon (red circles shown below) to enter the IMPACT program
download interface.
Before downloading, we need to connect the cable of the USB downloader with the JTAG port of the development board. What we need to do this time is online simulation. Plug in the development board and press the power switch on the development board. in
Boundary Scan is selected in the IMPACT environment. Right-click in the window and select Initialize Chain.
At thisPDFtime, JTAG will detect the PGA chip on the development board, as shown below:
