ubuntu8.04+skyeye1.2.4搭建linux2.6.24+s3c2410的模拟arm-linux开发环境

一，准备工具：

• 交叉编译工具：[url]http://www.handhelds.org/download/projects/toolchain/arm-linux-gcc-3.4.1.tar.bz2[/url]
• linux2.6.24的内核(ubuntu8.04)：[url]http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.tar.bz2[/url]
• arm模拟器skyeye：sudo apt-get install skyeye
• skyeye测试实例包：[url]http://sourceforge.net/project/showfiles.php?group_id=85554&package_id=166819[/url]

二，修改89x0网卡的驱动

将一下代码存为到内核根目录下，命名为：2410-cs8900.patch
然后： patch -p1 <2410-cs8900.patch  打补丁

三，修改配置内核

1.指定交叉编译器。内核顶层 Makefile中：

ARCH?= $(SUBARCH) CROSS_COMPILE ?=

ARCH?= $(SUBARCH) CROSS_COMPILE ?=

修改为：

ARCH :=arm CROSS_COMPILE   =/usr/local/arm/3.4.1/bin/arm-linux-<BR>

ARCH :=arm CROSS_COMPILE   =/usr/local/arm/3.4.1/bin/arm-linux-

2.设定s3c2410默认设置，修改启动地址和参数：

1）修改include/asm-arm/arch-s3c2410/map.h

#define S3C2410_CS6 (0x30000000)
to
#define S3C2410_CS6 (0xC0000000)

2）修改include/asm-arm/arch-s3c2410/memory.h

#define PHYS_OFFSET UL(0x30000000)
to
#define PHYS_OFFSET UL(0xC0000000)

3）make s3c2410_defconfig
4）make menuconfig

进入 [Device Driver] ->[ Character Driver] -> [Serial Driver]选项，保证“8250/16550 and compatible serial support”选项不被选中

修改启动参数为：
mem=32M console=ttySAC0 root=/dev/ram initrd=0xc0800000,0x00800000 ramdisk_size=2048 rw

Device Drivers-> Network device support-> Ethernet (10 or 100Mbit)
选中
 [*]   EISA, VLB, PCI and on board controllers

后出现
CS89x0 support  选中

四，编译，skyeye模拟

1.在skyeye-testsuite-2.3目录下建个mytest，将skyeye-testsuite-2.3/linux/s3c2410/s3c2410x-2.6.14中的skyeye.conf和initrd.image复制到mytest下

2.将编译好的内核linux-2.6.24/vmlinux拷贝到mytest下

3.启动：skyeye -e vmlinux
