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 */
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 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。。
