实用linux2.6.14在te2410开发板上的移植

1、LINUX2.6.14 在 TE2410 开发板上的移植作者：王 鹏 乔 鹏本实验是在 TE2410 开发板上实现的。TE2410 开发板是保定飞凌技术研发的一款 ARM9 开发（），基于三星公司的 ARM 处理器 S3C2410A。一 准备必要的文件首先去的 linux 内核http:/因为 linux2.6.14 内核需要更新版本的编译器，所以需要交叉编译器ftp:/ftp.handhelds./projects/toolchain/arm-linux-gcc-3.4.1.tar.bz2二 安装文件把 arm-linux-gcc 安装在 /usr/local/arm/3.4.1 目录下，安

2、装方法和安装 gcc2.95.3 和gcc3.3.2 是相同的！接下来需要解压 linux 内核，输入命令：root localhost hfrk# tar jxvf linux-2.6.14.tar.bz2内核被解压到 linux-2.6.14 目录下。三 修改 makefile 文件内核的编译是根据 makefile 文件的指示进行的， Makefile 文件来组织内核的各模块之间的关系，了各个模块之间的相互联系和依赖关系。首先修改 linux-2.6.14 的根目录下的 makfile 文件，须改的主要内容是目标代码的类型和为编译内核指定一个编译器。注释掉以下内容：#ARCH?= $(S

3、UBARCH)PILE?=增加如下内容：ARCH: = armPILE =/usr/local/arm/3.4.1/bin/arm-linux-四 修改相关的文件。11、修改 archarmmach-s3c2410devs.c 文件增加头文件定义#include#include#include/*end add*/Te2410 开发板 mtd 分区表：nameoffsetsizeflagvivi: 0 x000000000 x000200000128kparam: 0 x000200000 x00010000064kkernel: 0 x000300000 x001c000001M+768kr

7、ice_usb,&s3c_device_lcd;&s3c_device_wdt,&s3c_device_i2c;&s3c_device_iis,&s3c_device_nand, /*add here*/;五 解决 ECC 问题修改 drivers/mtd/nand/s3c2410.c 文件:vi drivers/mtd/nand/s3c2410.c找到 s3c2410_nand_init_chip()函数，在该函数体最后加上一条语句:chip-eccmode = NAND_ECC_E;保存,退出。六做完以上修改以后，内核编译以后就可以在 te2410 开发板上运行了。打开终端窗口，切换到 l

8、inux-2.6.14 目录下，输入命令：root localhost linux-2.6.14# make smdk2410_defconfigroot localhost linux-2.6.14#make meueconfig配置选项如下：System Type-*S3C2410 DMA supportGeneral setup-*NWFPE math emulationMemory Technology Devi(MTD)-*MTD partitioning support4*d line partition table parsingNAND Flash DeviceDrivers*

24、 2.6.14 的内核的驱动程序源代码，将其放在 drivers/net/arm/目录下面。#cp cs8900.c ./drivers/net/arm/ #cp cs8900.h ./drivers/net/arm/并在 cs8900_probe()函数中，memset (&priv,0,sizeof (cs8900_t);函数之后添加如下两条语句： raw_wri(0 x2211d110,S3C2410_BWSCON); raw_wri(0 x1f7c,S3C2410_BCON3);2、修改 drivers/net/arm/目录下的 Kconfig 文件，在最后添加如下内容： Config

25、 ARM_CS8900trise CS8900 supportdepends on NET_ETHERNET & ARM & ARCH_SMDK2410 helpSupport for CS8900A chipset based Ethernet cards. If you have a network (Ethernet) card of this type, say Y and read the Ethernet-HOWTO, available from as well as . To compile this driver as a module, choose M here and

26、read.The module will be called cs8900.o.内核系统配置文件由 2.4 版本的config.in 变成了 2.6 版本Kconfig 文件，在这个文件里面添加如上内容，则在运行 makeconfig 或者 make xconfig 命令的时候就会出现： CS8900 support这一选项。3、修改 drivers/net/arm/目录下的 Makefile 文件，在最后添加如下内容：10obj-$(CONFIG_ARM_CS8900) += cs8900.o2.6 版本内核的 Makefile 文件也与 2.4 版本的有所不同。添加以上语句，就会使内核在编译的时候根据配置将 cs8900A 的驱动程序以模块或静态的方式编译到内核当中。4、在/arch/arm/mach-s3c2410/mach-smdk2410.c 文件中，找到 smdk2410_iodesc结构数组，添加如下如下内容：vSMDK2410_ETH_IO, 0 x19000000, SZ_1M, MT_DEVICE修改之后变成了：sic struct map_desc smdk2410_iodesc initdata = /* nothing here yet */* Map the ethernet controller CS8
