1、移植Android内核到TQ2440开发板上1、从http://code.google.com/p/android/downloads/list上下载linux-2.6.25-android-1.0_r1.tar.gz2、将内核解压到用户目录，如/root/kernel.git3、进入kernel.git文件夹，如cd ~/kernel.git/4、修改arch/arm/plat-s3c24xx/common-smdk.c文件中的nand flash分区设置，如gedit arch/arm/plat-s3c24xx/common-smdk.c修改static struct mtd_partition smdk_default_nand_part[]结构体为：static struct mtd_partition smdk_default_nand_part[] = {        [0] = {                .name        = "TQ2440_uboot",                .size        = 0x00040000,                .offset        = 0x00000000,        },        [1] = {                .name        = "TQ2440_kernel",                .offset        = 0x0004C000,                .size        = 0x00200000,        },        [2] = {                .name        = "TQ2440_yaffs2",                .offset        = 0x0024C000,                .size        = 0x03DB0000,        }};5、在http://www.codesourcery.com/gnu_toolchains/arm/portal/release644网站上下载IA32 GNU/Linux TAR。6、将文件解压到用户目录，如/usr/local/arm/arm-2008q37、进入arm-2008q3/bin文件夹，如cd ~/arm-2008q3/bin/8、添加当前路径进入环境变量，如export PATH=$PWD:$PATH，或修改~/.bashrc文件并重新登录9、进入内核文件夹，如cd ~/kernel.git/10、修改Makefile文件，如gedit Makefile更改ARCH和CROSS_COMPILE#ARCH                ?= $(SUBARCH)ARCH                ?= arm#CROSS_COMPILE        ?= arm-eabi-CROSS_COMPILE        ?= arm-none-gnueabi-11、使用make s3c2410_defconfig，默认配置2410内核12、运行make menuconfig(1) 确保System Type ---> ARM system type ()中的内容为Samsung S3C2410, S3C2412, S3C2413, S3C2440, S3C2442, S3C2443(2) 确保System Type ---> S3C2410 Machines ---> SMDK2410/A9M2410被勾选(3) 取消选择与Goldfish相关的内容Device Drivers ---> Character devices ---> < > Goldfish TTY DriverDevice Drivers ---> Power supply class support ---> < >   Goldfish battery driver (NEW)Device Drivers ---> Real Time Clock ---> < >   GOLDFISH (NEW)Device Drivers ---> Graphics support ---> Support for frame buffer devices ---> < >   Goldfish Framebuffer(4) 选择S3C2410 LCD相关的内容Device Drivers ---> Graphics support ---> Support for frame buffer devices ---> <*>   S3C2410 LCD framebuffer supportDevice Drivers ---> Graphics support ---> Bootup logo --->    Standard black and white Linux logoDevice Drivers ---> Graphics support ---> Bootup logo --->    Standard 16-color Linux logoDevice Drivers ---> Graphics support ---> Bootup logo --->    Standard 224-color Linux logo(5) 选中Android内核必须选项Kernel Features ---> Use the ARM EABI to compile the kernelGeneral setup ---> Use full shmem filesystemGeneral setup ---> Enable Android's Shared Memory SubsystemSystem Type ---> Support Thumb user binariesDevice Drivers ---> Android ---> Android log driverDevice Drivers ---> Android ---> <*> Binder IPC Driver(6) 尽量选中Android内核可选选项Device Drivers ---> Android ---> RAM buffer consoleDevice Drivers ---> Android ---> Android timed gpio driverDevice Drivers ---> Android ---> Only allow certain groups to create sockets

上面的我就不赘述了，下面是我遇到的问题：

首先根据TQ2440的参考手册

移植LCD驱动，不然没法显示啊，用的内核是2.6.25的和android的差不多，所以就按照这个修改了，这个问题倒不是很多。

移植DM9000E网卡驱动，这个移植过程中发现drivers/net/dm9000.c好像被修改过了，还有就是参考手册上面的，有个不知道具体位置，不过我就按照自己的思路来。

编译过程中，很多问题，都一个个的修改了，没有什么大的问题，就是不知道逻辑上有没有问题。

因为我要的是NFS挂载的，所以移植了网卡驱动，其他的我就不知道要先移植哪一个了，索性直接下载试试。

移植到板子上了，启动。。。

瞧出错了，仔细网上查了下，是u-boot机器码和内核的机器码不同的原因。

两种解决方法

1修改内核机器码：arch/arm/tools/mach-types

379行的  362为内核机器码 修改为168

2修改u-boot机器码：u-boot-1.1.6/include/asm-arm/mach-types.h

377行的 168改为 362，

这里我修改了内核的，我感觉方便。

今天就到这里，至于上面的网卡驱动和LCD驱动，还没有验证。
