构建可运行Armbian (Ubuntu/Debian)，基于NanoPi M4V2的多合一Linux PC

本文共计1642字，预计阅读4分钟

在我对带有树莓派 4“RPI 一体式”PC的评测结束时，我注意到该系统似乎也与 NanoPi M4V2 单板计算机兼容。所以我就打算试试，我现在已经试过了，事实证明在 10.1 英寸显示屏内组装电路板比我最初想象的要容易一些。这意味着我现在拥有一台运行 Ubuntu Hirsute 或 Debian Buster（可更换）和 Armbian XFCE 桌面环境的 NanoPi M4V2 一体机了。这个一体机大多数功能都是可以正常运行的，包括显示和无线连接，但触摸屏功能仍然有一些问题。

以下是我最初遵循的步骤：

从Armbian下载ArmbianBuster XFCE镜像，并用类似于USBimager的工具将其烧录到microSD卡。
将 microSD 卡插入开发板。
在显示器中安装 USB Type-C 和 HDMI-A 适配器。
将 NanoPi M4V2 SBC 的 USB Type-C 和 HDMI 端口插入适配器。
安装显示套件中的RPI3侧板，带有USB端口、以太网开口、下方天线接口。
用四颗螺丝（或三颗，因为我丢了一颗）将电路板固定在显示器上。
安装用于触摸屏显示器的 USB 电缆（绿色、白色、黑色）。
将两个 SMA 连接器连接到 RPI3 侧板的剩余两个孔

合上显示器的底盖，并用产品提供的螺丝固定它
安装两根 2.4/5.8 GHz 天线

连接电源线，似乎就大功告成？

实际上是，没那么快！当 Armbian 启动时，它会要求用户在终端中输入新的 root 密码。所以我连接了我的无线键盘 USB接收器，然后，我居然无法打字输入。我借了一个 USB 键盘，但我还是不能打字输入。嗯？这是怎么回事呢？接着我就断开 USB 触摸屏的连接线，然后就成功了！之后我就能够使用无线鼠标和键盘完成设置、配置 WiFi 和浏览网页了。

触摸屏不工作而且还导致其他 USB 设备不工作的问题其实真的很奇怪。那么，接下来我们一起来看看当我们连接 USB 电缆时会发生什么吧，如下所示：

刚开始操作的时候它很好地识别出来了，但随后出现了错误，最终xHCI主机停止，所有 USB 外围设备也都断开了连接。Debian Buster 镜像运行 Linux 4.4，所以我猜想可能是驱动程序的问题？我在 Linux 5.10 上尝试了 Armbian Bullseye（客户端/无头）镜像，但还是发生了类似的问题。

在 Armbian 中向下滚动，Linux 5.13 也有不稳定的镜像。所以，我就用 XFCE 刷了 Ubuntu Hirsute，但却没有任何改变，如下所示：

不过，我还是可以使用 Ubuntu 镜像，而且浏览网页也没有任何问题。唯一比较烦的还是 USB 触摸屏问题。

之后，我用 modprobe 加载 hid-multitouch 模块也并没有解决这个问题。其实，TSTP Mtouch 驱动程序成为 Linux 内核的一部分已有好几年了，所以这极有可能是硬件问题。

USB 线只传输 GND 和数据信号，因此 5V 信号应该还是来自显示器中的另一个位置，我怀疑 5V 信号或接地可能也存在问题，这才导致 USB 主机将其完全关闭了。总之，到目前为止我还没有找到什么好的解决办法。
