Linux-2.6.30内核在TE2410上的移植

Linux-2.6.30内核在TE2410上的移植

在网上看到linux.2.6.30内核的socket的时间戳比较好，数据包的接收和发送都加盖了时间戳，而以后的版本，只有数据包的接收才会加盖时间戳，而且还支持硬件时间戳！这以后会用到，所以开始先把linux2.6.30移植好！

硬件是：TE2410
软件环境：UBUNTU 10.14
arm-linux-gcc 4.3.2

先下载一个linux.2.6.30内核源码

一、先修改Makefile

ARCH ?= $(SUBARCH)

CROSS_COMPILE ?=

改为:

ARCH ?= arm

CROSS_COMPILE ?=/usr/local/arm/4.3.2/bin/arm-linux-

二、修改分区
根据vivi里的分区信息修改文件：
～／arch/arm/plat-s3c24xx/common-smdk.c

修改1
static struct mtd_partition smdk_default_nand_part[] = {

[0] = {

.name = "vivi",

.size = 0x00020000,

.offset = 0,

},

[1] = {

.name = "param",

.offset = 0x00020000,

.size = 0x00010000,

},

[2] = {

.name = "kernel",

.offset = 0x00030000,

.size = 0x001c0000,

},

[3] = {

.name = "root",

.offset = 0x00200000,

.size = 0x00400000,

},

[4] = {

.name = "user",

.offset = 0x00600000,

.size = 0x03a00000,

}

};

修改2
static struct s3c2410_platform_nand smdk_nand_info = {

.tacls = 0, //default is 20

.twrph0 = 30, //default is 60

.twrph1 = 0, //default is 20

.nr_sets = ARRAY_SIZE(smdk_nand_sets),

.sets = smdk_nand_sets,

};

修改3
static struct platform_device __initdata *smdk_devs[] = {

&s3c_device_nand,

&smdk_led4,

&smdk_led5,

&smdk_led6,

&smdk_led7,

};

三、修改时钟频率
修改文件
~/arch/arm/mach-s3c2410/mach-smdk2410.c

static void __init smdk2410_map_io(void)

{

s3c24xx_init_io(smdk2410_iodesc, ARRAY_SIZE(smdk2410_iodesc));

s3c24xx_init_clocks(12000000);

s3c24xx_init_uarts(smdk2410_uartcfgs, ARRAY_SIZE(smdk2410_uartcfgs));

}

四、修改ECC (是否必要呢？ 我还没确定）
修改～／drivers/mtd/nand/s3c2410.c
在这个 static void s3c2410_nand_init_chip()函数中

chip->ecc.mode = NAND_ECC_NONE; //default is NAND_ECC_NONE

}

if (set->ecc_layout != NULL)

chip->ecc.layout = set->ecc_layout;

if (set->disable_ecc)

chip->ecc.mode = NAND_ECC_NONE;

要修改的文件就这四个，其它的要通过配置内核来完成的

五、、
然后用S3C2410的默认配置文件
命令：

#make s3c2410_defconfig

六、
＃make menuconfig

3.
对于其它的驱动和文件系统能不要的尽量不要(如：USB，RTC，CS8900，DM900，LCD，ATA），
要点就是先把Linux启动起来，以后再慢慢添加其它要用到的东西，千万不要急于求成，一下子把很多模块
一并加进来，这样找错非常难。

我就是把网络驱动全部去掉，文件系统也全部去掉，只留下Cramfs 文件系统支持，还有一些看着没用的驱动一并不要了，主要是减小内核，内核过大也会造成很多问题的，总之就是越简单越好。

如果途中有错，认真看一下错的模块，然后通过

make menuconfig 将出错的模块暂时不要，这样一步一步的消除错误！

七、

make zImage
