Linux2.6.30.4移植TE2440II開發(fā)板

1、linux移植te2440ii開發(fā)板首先，從官網(wǎng)上下載linux-的內(nèi)核?？梢哉业?。新建名目mkdir /home/haker，將內(nèi)核源碼包解壓到hacker/名目下tar zxvf linux-.tar.gz1)給內(nèi)核打jaffs2補(bǔ)丁下載最新的驅(qū)動(dòng) . fs2.tar.gz?view=tar解壓到/home/hacker/下tar zxvf yaffs2.tar.gz進(jìn)入名目cd yaffs2給內(nèi)核打補(bǔ)丁./patch-ker.sh c /home/hacker/linux-加上c 他會(huì)自動(dòng)解壓到后面的名目中勝利后會(huì)打印信息：

2、updating /home/hacker/linux-/fs/kconfigupdating /home/hacker/linux-/fs/makefile2)修改機(jī)器碼臨時(shí)我用法的是飛凌的boot，自己的boot還沒有徹低做好，飛凌boot的默認(rèn)機(jī)器碼是193，修改arch/arm/tools/mach-types，將s3c2410 arch_ s3c2410 193 刪掉然后將s3c2440 arch_s3c2440 s3c2440 362修改為s3c2440 arch_s3c2440 s3c2440 1933）修改目標(biāo)板的arch和編譯器路徑修改linu

3、x/下的makefile將arch ？= $(subarch)cross_compile ?=修改成arch ?= armcross_compile ?= /usr/local/arm/4.3.2/bin/arm-linux-4）增強(qiáng)devfs文件管理器支持修改fs/kconfig，找到menu “pseudo filesystems”添加config devfs_fsbool “/dev file system support (obsolete)”default yconfig devfs_mountbool “automatially mount at bool”defa

4、ultdepends on devfs_fs5）修改晶振頻率arch/arm/mach-s3c2440/mach-smdk2440.c/*s3c24xx_init_clocks(16934400);*/ s3c24xx_init_clocks(12000000);6)修改mtd分區(qū)，因?yàn)樽约旱膗boot還沒有徹低做好，臨時(shí)用飛凌的boot的分區(qū)，修改文件arch/arm/plat-s3c24xx/common-smdk.cstatic struct mtd_partition smdk_default_nand_part = 0 = .name = "boot",.size

5、 = 0x00100000,.offset = 0,1 = .name = "myapp",.size = 0x003c0000,.offset = 0x00140000,2 = .name = "kernel",.size = 0x00300000,.offset = 0x00500000,3 = .name = "fs_yaffs",.size = 0x03c00000, /60m.offset = 0x00800000,4 = .name = "wince",.size = 0x03c00000,.offse

6、t = 0x04400000,;7)關(guān)閉ecc校驗(yàn)文件drivers/mtd/nand/s3c2410.c函數(shù)：s3c2410_nand_init_chip/*chip-ecc.mode = nand_ecc_soft; */ chip-ecc.mode = nand_ecc_none;這個(gè)有兩個(gè) 軟件校驗(yàn)和硬件校驗(yàn)都要關(guān)掉8）修改nandflash驅(qū)動(dòng)，修改drivers/mtd/nand下面的nand_bbt.c文件：static struct nand_bbt_descr largepage_memorybased = .options = 0,.offs = 0,.len = 1, /

7、 原數(shù)值為2，支持2k每頁的flash修改為1。k9f1g08，k9f2g08是2k每頁的flash.pattern = scan_ff_pattern;static struct nand_bbt_descr largepage_flashbased = .options = nand_bbt_scan2ndpage,.offs = 0,.len = 1, /原數(shù)值為2，支持2k每頁的flash修改為1。k9f1g08，k9f2g08是2k每頁的flash.pattern = scan_ff_pattern;9）配置內(nèi)核make menuconfig首先加載s3c24xx系列的通用配置，然后在此基礎(chǔ)上修改配置完后將配置文件保存為.conf
