4.2. Troubleshooting for Launching BTS

No Available Serial Ports

Figure 6. Failure of "Could not find any available serial ports"
  1. Check if the micro-USB is connected physically.
  2. Check if the USB Serial Port driver is installed successfully.
    1. On your Windows taskbar, right click Start (Windows logo) > Computer Management.
    2. Check if the UART ports of the Agilex™ 5 FPGA E-Series 065B Modular Development Kit can be recognized by the operating system. The UART ports have the following characteristics:
      • Manufacturer = FTDI
      • Four consecutive serial ports number. For example, COM8/COM9/COM10/COM11.
    3. If no valid UART ports are in the list, it may be due to USB Serial Port driver is not installed. You can download and install the FTDI* USB Serial Port driver. Refer to the related information for the download link.

The issue roots that the UART does not work correctly or the Nios® software in the System MAX® 10 does not work well, follow the check list below:
  1. Check if the BTS is launched before the board is ready.
  2. Check if there are some third-party UART tools that have occupied the port.
  3. Check if there are other BTS instances and close them.
  4. Check if uninstall and install UART device in "Computer Management" can solve the issue.
  5. Check if the LED DS8 on the Carrier board is blinking, as it indicates that the Nios® software is running well. Otherwise, power cycle the board or reprogram the System MAX® 10.
