寫入 image 至 SDHC 卡

// 下載軟體 win32diskimager
https://launchpad.net/win32-image-writer

開啟軟體，將所下載的 image 寫入到 SDHC。

設定 UBoot 以 SDHC Card 開機

// 檢查 UBoot version 需 3.4.19 以後，才有支援 SDHC 開機
Windows XP 與 SheevaPlug 用 mini-USB 接上，開啟 PuTTY 並開啟 Console 視窗，SheevaPlug 插上電源開機。

透過 PuTTY 的視窗可以看到開機的狀態，當出現

Hit any key to stop autoboot... <按下任一鍵>
Marvell >>

當看到 Marvell 提示字元時，表示已進入了 UBoot 命令模式，輸入以下指令：

Marvell>> setenv mainlineLinux yes
Marvell>> setenv arcNumber 2097
Marvell>> setenv bootargs_console console=ttyS0,115200
Marvell>> setenv bootcmd_mmc 'mmcinit; ext2load mmc 0 0x0800000 /uInitrd; ext2load mmc 0 0x400000 /uImage'
Marvell>> setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x400000 0x0800000'
Marvell>> saveenv
Marvell>> reset 

若一切順利應該會開始啟動 SDHC 的 PlugPBX 系統。

TIPs:

若開機訊息不小心跳過，可以用 root 登入後，執行 reboot 重開機再來一次，或者拿尖物戳 SDHC 槽右側的小孔。
