MC2410 Port 2.6.11.7 过程分享

本次port  linux2.6.11.7 的过程：参考了嵌入式高手superlp的经验：

1：download kernel


decompress and no patch is needed

b>install the gcc compiler
ftp://ftp.handhelds.org/projects/toolchain/arm-linux-gcc-3.4.1.tar.bz2


2 modify kernel source

a>add your nand flash partition information
modify the arch/arm/mach-s3c2410/devs.c file
for example:

/***********add here*************/
#include
#include
#include
/***********end add*************/


//hujun add  start
static struct mtd_partition partition_info[] ={
{
    name: "loader",
    size: 0x00020000,
    offset: 0,
},

{
    name: "param",
    size: 0x00010000,
    offset: 0x00020000,
},
{
    name: "kernel",
    size: 0x001c0000,
    offset: 0x00030000,
},    
{
    name: "root",
    size:   0x00400000,
    offset: 0x00200000,
    mask_flags: MTD_WRITEABLE,
},
{
    name: "user",
    size:   0x03a00000,
    offset: 0x00600000,
}
};

struct s3c2410_nand_set nandset ={
nr_partitions: 5 ,
partitions: partition_info ,
};

struct s3c2410_platform_nand  hujunPlatform={
tacls:0,
twrph0:30,
twrph1:0,
sets: &nandset,
nr_sets: 1,
};

//hujun add end

struct platform_device s3c_device_nand = {
    .name          = "s3c2410-nand",
    .id          = -1,
    .num_resources      = ARRAY_SIZE(s3c_nand_resource),
    .resource      = s3c_nand_resource,
//hujun add start
         .dev={
     .platform_data = &hujunPlatform        //注意此处不要","号  **********add here*****
//hujun add  end
};

EXPORT_SYMBOL(s3c_device_nand);  //此句原来就有，此处列出是要求上面加的代码在此句之前。


b>add "&s3c_device_nand" to the __initdata in the arch/arm/mach-s3c2410/mach-smdk2410.c
 
static struct platform_device *smdk2410_devices[] __initdata = {
    &s3c_device_usb,
    &s3c_device_lcd,
    &s3c_device_wdt,
    &s3c_device_i2c,
    &s3c_device_iis,

        &s3c_device_nand,     //hujun add         //在这里加，注意有逗号
};
注意别加错了地方， 刚开始我加在
static struct map_desc smdk2410_iodesc[] __initdata = {
  /* nothing here yet */
//hujun add start
 &s3c_device_nand          
//hujun add end
};
结果内核启动时没有发现mtd分区信息。  具体原因待查。


c>disable the ecc


modify the drivers/mtd/nand/s3c2410.c
for example:
/**** chip->eccmode = NAND_ECC_SOFT; **/
chip->eccmode = NAND_ECC_NONE;

3 config the kernel


a>modify the MakeFile

for example:

##SUBARCH := $(shell uname -m | sed -e s/i.86/i386/ -e s/sun4u/sparc64/ \
## -e s/arm.*/arm/ -e s/sa110/arm/ \
## -e s/s390x/s390/ -e s/parisc64/parisc/ )


SUBARCH :=arm

##CROSS_COMPILE ?=
CROSS_COMPILE ?=/usr/local/arm/3.4.1/bin/arm-linux-



b>make menuconfig....
 the config file  is       

文件:	config.tar.bz2
大小:	4KB
下载:	下载

                                                                              
 说明： 我在kernel配置中没有使用cmd line  ，是在vivi 中
vivi>param set linux_cmd_line "noinitrd root=/dev/mtdblock/3  init=/linuxrc console=ttySAC0"
param save
load flash kernel  t

boot

上面改动的文件一起保存如下

一定要注意启动信息， 因为我们烧写的是内核， 内核是否能跑起来，从启动信息可以找到问题出在哪里，
其实这跟调试程序是一个道理。
