在http://www.uclinux.org/pub/uClinux/arm-elf-tools/ 下载arm-elf-tools-20030314.sh

在http://www.uclinux.org/pub/uClinux/dist/ 下载uClinux-dist-20041215.tar.gz

执行./arm-elf-tools-20030314.sh，安装工具链，执行tar zxvf uClinux-dist-20041215.tar.gz并进入uClinux-dist目录。

• 在linux-2.4.x/arch/armnommu/vmlinux-armv.lds.in文件中找到以下行:

*(got) /* Global Offset table */

在其之后添加如下语句：

romfs_data = .;

romfs.o

romfs_data_end = .;

注意，等号两边都要有空格。

• 在vendors/Samsung/4510B/Makefile 文件中添加image目标的第三行，增加一条语句：arm-elf-ld -r -o $(ROOTDIR)/$(LINUXDIR)/romfs.o -b binary $(ROMFSIMG)

如下为增加之后：

image:

[ -d $(IMAGEDIR) ] || mkdir -p $(IMAGEDIR)

genromfs -v -V "ROMdisk" -f $(ROMFSIMG) -d $(ROMFSDIR)

arm-elf-ld –r –o /root/uclinux/uClinux-dist/linux-2.4.x/romfs.o –b binary /root/uclinux/uClinux-dist/images/romfs.img

(/root/uclinux是我存放uClinux-dist的目录)

• 修改linux-2.4.x/drivers/char/serial_samsung.c, 找到uart_config数组,把如下项：

{ "S3C4510B", 1, 0}, /* Samsung S3C4510B uart support */

修改为：

{ "S3C4510B", 128, 0}, /* Samsung S3C4510B uart support */

• 执行make menuconfig

此处设置成S3C44B0X

• 修改config/.config，注释掉CONFIG_USER_OLD_PASSWORDS
• 执行make dep
• 执行make lib_only
• 执行make user_only
• 执行make romfs
• 修改linux-2.4.x/arch/armnommu/mach-S3C44B0X/arch.c

将23行的S3C44B0X改为S3C44B0

在代码末尾添加”}”

修改linux-2.4.x/arch/armnommu/kernel/head-armv.S

将206行以及439行的S3C44B0X改为S3C44B0

• 执行make

make成功后，uClinux-dist目录里将出现一个images目录。

我编译的是uClinux-dist-20041215.tar.gz

在编译过程中并没有出现错误。

我的tool-chain是都是下面这个URL的RPM包

代码:

http://www.uclinux.org/pub/uClinux/arm-tools/RPMS/

arm-elf-binutils-2.12.1-5.i386.rpm

arm-elf-gcc-2.95.3-5.i386.rpm

arm-elf-gdb-5.2-0.i386.rpm

arm-elf-uClibc-0.9.20-2.i386.rpm

操作系统是FC1 for x86

skyeye的版本是0.9.5

可能是tool-chain中的rpm包又问题

我换了一个tool-chain(arm-elf-tools-20030314.sh)可以正常运行了。。
