SheevaPlug

使用 mini-USB 登入 SheevaPlug

由於 SheevaPlug 無法直接連結螢幕，更無法接上鍵盤，所以要登入內建的 Ubuntu，有兩種方法：

1. 網路上有 DHCP Server，且有權限可以讀取 IP 租用的紀錄。
   Ubuntu 的網路設定預設為 DHCP 模式，透過讀取網路上的 DHCP Server 的 IP 租用紀錄，找出 SheevaPlug 所租用 IP 位址，然後使用 PuTTY 以 SSH 模式連結 SheevaPlug。
2. 以 Windows 操作而言，安裝 FTDI 2232 驅動程式，使 Windows 可以透過 mini-USB cable 以 RS232 模式登入 SheevaPlug；以 Linux 操作者，請參考這篇 Serial terminal。

由於第一項實用性較低，本章節將以第二項操作為主要說明內容：

// 下載 FTDI 2232 Driver

SheevaPlug_Host_SWsupportPackageWindowsHost1.2.zip

Driver 安裝方式是，將壓縮檔解壓縮，然後將 SheevaPlug 插上電源，並與 WindowsXP 用 mini-USB 連接，此時 WindowsXP 會偵測到有新裝置，並出現安裝驅動程式的視窗，選擇手動安裝，並將目錄指向剛剛解壓縮的檔案目錄，若一切正常，會陸續有三次的驅動安裝，每次都指向同個目錄即可；若在這裡，WindowsXP 始終沒有偵測到適合的驅動程式，請改用本站所修改的 driver。

// 找出虛擬的 COM 裝置名稱
將 SheevaPlug 插上電源，並與 WindowsXP 用 mini-USB 連接。
WindowsXP > 開始 > 設定 > 控制臺 > 效能及維護 > 系統管理工具 > 電腦管理 > 裝置管理員

連接埠 (COM 和 LPT)
--> USB Serial Port (COM9)

NOTE: 這裡所顯示的 COM9，編號在不同電腦下可能會有所不同。

// 以 PuTTY 軟體登入系統
開啟 PuTTY，

Connection type : Serial
Serial line : COM9
Speed : 115200

連接後若出現黑畫面，多按幾次 Enter，若正常會出現 debian 登入提示。
