我正在开发Microsemi SmartFusion 2 Maker-Board。
我使用不同版本的软件话务台做了几次。 调试似乎与5.1和4.0一起正常工作但是当我打开终端程序时，它找不到除FlashPro5端口之外的任何串口。 我看到了板上旋转的LED，但我不确定其他2个任务是否正常，我无法向ESP8266发送任何AT命令。 以上来自于谷歌翻译 以下为原文 I am working on the Getting Started with the Microsemi SmartFusion 2 Maker-Board. I have done everything a couple of times with different versions of Softconsole. Debug seem to work fine with 5.1 and 4.0 but when I open a terminal program, it cannot find any serial port other than the FlashPro5 Port. I see the spinning leds on the board but i am not sure the other 2 tasks are working and i can’t send any AT commands to ESP8266.

板上应该有四个串口。
SmartFusion的UART连接到第三个FlashPro端口。 例： 以上来自于谷歌翻译 以下为原文 There should be four serial ports created by the board. The SmartFusion’s UART is connected to the third FlashPro port. Example: |

这不是一个答案，这就是教程所说的，但我说我的实现没有串口。
问题是导致这种情况的原因。 FreeRTOS版本？ Libero版本？ 我使用的是libero 11.9和freertos 9 以上来自于谷歌翻译 以下为原文 This is not an answer, that is what tutorial says but i am saying there is no serial port with my implementation. Question is what can cause this. FreeRTOS version? Libero version? I m using libero 11.9 and freertos 9 |

你说FlashPro端口仍然存在，因此不清楚你看到了哪些端口。
串行端口由板上的FTDI芯片创建。 如果该芯片工作正常，它将枚举主机上的4个COM端口，无论SmartFusion如何编程。 这意味着存在通信问题（可能与主机驱动程序有关）或IC本身存在问题。 驱动程序安装正确吗？ 设备管理器中是否显示任何错误？ 以上来自于谷歌翻译 以下为原文 You said the FlashPro port was still present so it was unclear which ports you were seeing. The serial ports are created by the FTDI chip on the board. If that chip is working properly, it will enumerate with 4 COM ports on the host computer regardless of how the SmartFusion is programmed. This implies that either there is a communication problem (probably with the host drivers) or a problem with the IC itself. Did the drivers install correctly? Does anything show up in Device Manager with an error? |

对不起，解释不清楚。
设备管理器中没有任何错误。 将电路板连接到PC时，只有一个FlashPro5端口。 我还有Creative板，它在连接时也只显示一个FlashPro端口。 如何检查驱动程序是否正确安装或FTDI芯片是否正常工作？ 以上来自于谷歌翻译 以下为原文 Sorry for the unclear explanation. There is not any error in the device manager. There is only one FlashPro5 Port when i connect the board to the PC. I also have the Creative board and it also show only one FlashPro Port when connected. How can I check the drivers are installed correctly or FTDI chip is working correctly? |

只是为了澄清，当您能够看到一个FlashPro端口时，设备管理器中没有其他设备？
不一定是COM端口，但未知设备，其他端口可能被错误地分配给了什么？ 当您重新安装驱动程序时，是手动执行还是让Windows自动执行？ 应在Libero安装目录中提供驱动程序以进行手动安装。 由于您提到卸载驱动程序会导致出现四个未知设备，我认为我们可以排除硬件问题并且驱动程序安装过程是问题所在。 我不清楚为什么你正在失去其他3个端口。 以上来自于谷歌翻译 以下为原文 Just to clarify, there are no other devices present in Device Manager when you are able to see the one FlashPro port? Not necessarily COM ports, but unknown devices, anything that the other ports may have been incorrectly assigned to? When you reinstalled the drivers did you do it manually or let Windows do it automatically? The drivers should be available in your Libero installation directory for manual installation. Since you mentioned that uninstalling the driver causes four unknown devices to show up, I think we can rule out the hardware being the problem and that the driver installation process is the issue. It’s not clear to me why exactly you’re losing the other 3 ports though. |

实际上我现在检查了它，当我插入设备时有4个u*** fp5串行转换器。
以上来自于谷歌翻译 以下为原文 Actually i checked it now and there are 4 u*** fp5 serial converter when i plug the device. |

谢谢你的回答，这对解决方案来说已经足够了。
当我右键单击并打开USB FP5串行转换器A的属性时，在高级选项卡中有一个选项“加载VCP”。 仅为Converter C检查此选项。 当我检查所有这些并拔下插头时 - 重新插入设备，所有端口都在端口（COM＆amp; LPT）下 我见过的FlashPro5端口是UART端口。 但是波特率显示为9600而不是115200.您需要将其更改为115200以与电路板通信。 以上来自于谷歌翻译 以下为原文 Thank you for your answer, it was enough for the solution. When i right click and open the properties of the USB FP5 Serial Converter A there was an option “Load VCP” in the advanced tab. This option was checked only for Converter C. When i checked it for all of them and unplug - reinserted the device, all ports were under Ports (COM & LPT) The FlashPro5 port that i already seen was the UART port. The baud rate however shown as 9600 not 115200. You need to change it to 115200 to communicate with the board. |
