5. Operating Instructions
This section outlines general operating procedures for the ALINX AXU2CGB development board.
5.1. Basic Operation
- Power On/Off: Use the power switch or disconnect the power adapter to power off the board. Always ensure proper shutdown procedures are followed to prevent data corruption.
- System Boot: The board will typically boot from the eMMC Flash or QSPI Flash. If a bootable image is present on the Micro SD card, it may boot from there depending on the boot mode settings.
- Accessing the System:
- Via DisplayPort: If a display is connected, the graphical user interface (if available) will be shown.
- Via USB UART: Connect a USB-to-serial adapter to the USB UART port and use a terminal emulator (e.g., PuTTY, Tera Term) on your host PC to access the serial console.
- Via Ethernet: Access the board via SSH or other network protocols once an IP address is assigned.
5.2. Programming and Debugging
- FPGA Programming: Use Xilinx Vivado or Vitis to compile and load FPGA bitstreams onto the Zynq UltraScale+ PL (Programmable Logic) section.
- Software Development: Develop applications for the ARM processors using Xilinx Vitis IDE. This includes bare-metal applications, Linux-based applications, and AI acceleration with Vitis AI.
- JTAG Debugging: Connect a JTAG debugger to the JTAG port for hardware debugging of both the PS (Processing System) and PL.
- Expansion Ports: Utilize the 40-pin expansion ports to connect various ALINX modules, such as camera modules, TFT LCD screens, or custom peripherals.
6. Maintenance
Proper maintenance ensures the longevity and reliable operation of your ALINX AXU2CGB development board.
- Cleaning: Keep the board clean and free from dust. Use a soft, dry brush or compressed air to remove dust from components and connectors. Avoid using liquids or abrasive cleaners.
- Environmental Conditions: Operate the board within the specified working temperature range (0°C to 70°C). Avoid extreme humidity, direct sunlight, or environments with excessive vibrations.
- Firmware Updates: Regularly check the ALINX official website for firmware, driver, and software updates. Keeping your board's software up-to-date can improve performance and stability.
- Handling: Always handle the board by its edges to avoid touching sensitive components. Use anti-static precautions (e.g., anti-static wrist strap) when handling to prevent electrostatic discharge (ESD) damage.
- Storage: When not in use, store the board in its original anti-static packaging or a suitable anti-static container in a cool, dry place.
7. Troubleshooting
This section provides solutions to common issues you might encounter.
- Issue: Board does not power on.
-
- Solution: Verify the power adapter is correctly connected and providing the specified voltage and current. Check the power cable for damage. Ensure the power switch (if present) is in the ON position.
- Issue: No display output via Mini DP.
-
- Solution: Ensure the display cable is securely connected to both the board and the monitor. Check if the monitor is set to the correct input source. Verify that the software running on the board is configured to output to the DisplayPort. An ALINX customized DP to HDMI cable may be required (sold separately).
- Issue: USB devices are not recognized.
-
- Solution: Try connecting the USB device to a different USB 3.0 port. Ensure the device drivers are installed on the board's operating system (if applicable). Check the power consumption of the USB device; some high-power devices may require an external power source.
