This thesis invesigates the kernel of uclinux, which is different from the mainstream linux. according to the mmu - less embedded micro - processors, uclinux removes the parts correspond to the virtual memory management, changes some of the system call interfaces and adopts the binary flat format to allow the program to be executed in place. the thesis also describes how to port uclinux to m68k platform and run it smoothly
本文詳細闡述了uclinux針對嵌入式應用、基於無內存管理單元的特性對標準linux進行的改良。主要包括沒有虛擬內存機制的內存管理，系統介面的改變，獨特的運行方式xip和可執行文件格式bflt 。本文同時介紹了uclinux的板級移植過程以及如何運行一個完整的uclinux操作系統。 -
Then it works over the methods of constructing the embedded internet service system with linux which mainly include the following aspects : how to boot embedded linux system ; how to revise the linux kernel to adjust it to embedded application, especially how to revise the virtual memory mechanism ; how to mount a file system to embedded linux system ; methods of developing device drivres ; how to connect embedded linux system to internet
然後，詳細研究分析了如何利用linux構建嵌入式internet服務系統，其中主要包括下面幾個方面的內容：如何引導嵌入式linux系統；如何修改linux內核以適應嵌入式應用的需要，這其中主要分析了對虛擬內存機制的修改；如何在嵌入式linux系統中掛接文件系統；開發硬體設備驅動程序的方法；如何將嵌入式linux系統接入internet 。 -
When we develop the application based on the embedded linux system we must first resolve how to build the embedded linux os. during the building we must consider several problems such as how to boot linux, whether is the virtual memory mechanism necessary, how to select the file system and how to eliminate the dependment on disk
