6. Depanare

If you encounter issues with your Zybo Z7-10 board, consider the following common troubleshooting steps:

• No Power Indication:
  • Verify that the power supply is correctly connected and providing the specified 5V.
  • Verificați cablul de alimentare pentru orice deteriorare.
• Probleme de conectare USB:
  • Ensure the USB cable is securely connected to both the board and the host computer.
  • Încercați un alt port USB sau cablu.
  • Install or update the necessary USB drivers for the Zynq device.
• FPGA Not Programming:
  • Confirm that the JTAG chain is correctly connected and recognized by your development software (e.g., Xilinx Vivado).
  • Ensure the correct bitstream or programming file este selectat.
  • Check for any error messages in the development software console.
• Probleme software/firmware:
  • Refer to Digilent's official support resources for specific software setup and known issues.
  • Ensure your development environment (e.g., Vivado) is up to date.
