Linux核心移植和根檔案系統製作（詳細步驟精講）

start_kernel是所有 Linux 平臺進入系統核心初始化後的入口函式，它主要完成剩餘的與硬體平臺相關的初始化工作，在進行一系列與核心相關的初始化後，呼叫第一個使用者程序－init 程序並等待使用者程序的執行，這樣整個 Linux 核心便啟動完畢。該函式所做的具體工作有：呼叫 setup_arch

Linux根檔案系統製作與各種掛載方式的實現

Linux根檔案系統的製作什麼是檔案系統計算機的檔案系統是一種儲存和組織計算機資料的方法，它使得對其訪問和查詢變得容易，檔案系統使用檔案和樹形目錄的抽象邏輯概念代替了硬碟和光碟等物理裝置使用資料塊的概念，使用者使用檔案系統來儲存資料不必關心資料實際儲存在硬碟（或者光碟）的地址為多少的資料

cpio命令與檔案系統製作

嵌入式開發過程中的檔案系統製作，往往是使用已經定製好的目錄及檔案進行製作，下面以實際的例子進行說明：假設當前目錄為rootdir,目錄結構如下： [email protected]:~# tree -L 2 rootdir rootdir |-- dev |--
