4. System Requirements

• Operating System: Windows (XP/7/8/10) or Linux.
• Software: Xilinx ISE (9.1-14.7) or Xilinx Vivado (all versions).
• Available USB Port.

5. Setup

Follow these steps to set up your ALINX AL321 USB Blaster:

1. Connect to Computer: Connect the USB Type-A end of the provided USB cable to an available USB port on your computer and the Mini-B end to the AL321 USB Blaster unit. The status LED on the blaster should illuminate, indicating power.
2. Driver Installation: Upon first connection, your operating system may attempt to install drivers automatically. If not, drivers are typically included with your Xilinx ISE or Vivado software installation. Refer to your Xilinx software documentation for specific driver installation instructions.
3. Connect to Target Device: Use the 10-Core 2.54mm Pitch Cable to connect the AL321 USB Blaster to the JTAG header on your Xilinx FPGA development board. Ensure correct pin orientation.

6. Operating Instructions

6.1 Pin Definition

Understanding the pinout is crucial for correct connection to your target FPGA board. Pin 1 is typically indicated on the device.

6.2 Interface Types

The AL321 USB Blaster supports two common JTAG interface spacings without requiring external conversion:

• 2.54mm Spacing 10 Pin Interface: This is a standard interface for many FPGA boards.
• 2.0mm Spacing 14 Pin Interface: This interface provides additional pins, often for ground or other signals.

The device automatically adapts to the target I/O voltage, simplifying connection.

6.3 Software Usage

Once connected and drivers are installed, open your Xilinx ISE or Vivado software. The AL321 USB Blaster should be detected as a programming cable. You can then use the software's programming tools (e.g., Impact for ISE, Hardware Manager for Vivado) to download bitstreams, program flash memory, or perform JTAG debugging on your FPGA device.

7. Specifications

• Model: AL321
• Supported Software: Xilinx ISE (9.1-14.7), Xilinx Vivado (all versions), Impact, Chipscope
• Supported Operating Systems: Windows, Linux
• Supported I/O Voltage Levels: 5V (TTL), 3.3V (LVCMOS), 2.5V, 1.8V, 1.5V
• Interface: JTAG, SPI flash PROM programming
• Connectivity: USB 2.0

8. Troubleshooting

If you encounter issues, consider the following:

• Device Not Detected: Ensure the USB cable is securely connected to both the computer and the AL321. Verify that the status LED on the blaster is on. Reinstall or update USB drivers if necessary.
• Programming Errors: Check the connection between the AL321 and the target FPGA board. Ensure the JTAG cable is correctly oriented and all pins are making good contact. Verify that the target FPGA board is powered on and configured correctly.
• Software Issues: Confirm that your Xilinx software (ISE or Vivado) is correctly installed and configured to recognize the AL321 programmer. Refer to Xilinx documentation for specific software setup.
• Voltage Mismatch: The AL321 automatically adapts to target I/O voltage. However, ensure your target board's voltage is within the supported range (1.5V to 5V).

9. Maintenance

To ensure the longevity and reliable operation of your ALINX AL321 USB Blaster:

• Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Avoid exposing the device to moisture or corrosive substances.
• Handle cables and connectors gently to prevent damage.
