port linux 2.6.11.7 kernel to s3c2410(SMDK2410)

port linux 2.6.11.7 kernel to s3c2410(SMDK2410)

                                      

 

1 preparation

my board is s3c2410 SMDK2410

a>download kernel

http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.11.7.tar.gz

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 <linux/mtd/partitions.h>

#include <asm/arch/nand.h>

#include <linux/mtd/nand.h>

/***********end add*************/

 

...

 

/*****************************add here***************************/

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: 0x00200000,

offset: 0x00200000,

mask_flags: MTD_WRITEABLE,

}, {

name: "user",

size: 0x03af8000,

offset: 0x00400000,

}

};

 

struct s3c2410_nand_set nandset ={

nr_partitions: 5 ,

partitions: partition_info ,

};

 

struct s3c2410_platform_nand superlpplatform={

tacls:0,

twrph0:30,

twrph1:0,

sets: &nandset,

nr_sets: 1,

};

/********************************end add****************************/

struct platform_device s3c_device_nand = {

.name = "s3c2410-nand",

.id = 0xec,

.num_resources = ARRAY_SIZE(s3c_nand_resource),

.resource = s3c_nand_resource,

.dev = {

.platform_data = &superlpplatform //***********add here*****

}

};

 

b>add "&s3c_device_nand" to the __initdata in the arch/arm/mach-

s3c2410/mach-smdk2410.c

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 ?=/toolchain/bin/arm-linux- ##according to your situation

b>make menuconfig....

7 conclusion

the basic function is ok now , next the ecc should be corrected and many

drivers should be added.(to be continued)
