向已经编译好的uClinux系统里加入自己的新程序

前段时间编译了uClinux后，一直没有抽出时间来测试，今天把skyeye拿出来实验了一下，以前正常！下面详细的说一说相关的步骤：

一。首先安装skyeye
[root@localhost root]#wget 192.168.5.89/skyeye.tar.tar
[root@localhost root]#tar jxvf skyeye.tar.tar
[root@localhost root]#cd skyeye-v1
[root@localhost skyeye-v1]#make

这样skyeye就安装完了，很简单，如果有什么不懂的地方，可以查看README
[root@localhost skyeye-v1]#cat READ | less

二。测试uClinux能否在skyeye下运行。
[root@localhost skyeye-v1]#cp ./binary/skyeye /root/uClinux-dist/
[root@localhost skyeye-v1]#cd /root/uClinux-dist
[root@localhost uClinux-dist]#vi skyeye.conf
#skyeye config file sample

[root@localhost uClinux-dist]#./skyeye -e ./linux-2.4.x/linux -c skyeye.conf

还好，可以运行！


三。向系统里加入自己的程序：

[root@localhost uClinux-dist]#vi test.c
#include
int main()
{
printf("this is an test program\n");
printf("written by 1jjk\n");
printf("Email:lingjiujianke@gmail.com")
printf("blog: http://1jjk.cublog.cn");
return 0;
}

:wq

[root@localhost uClinux-dist]#arm-elf-gcc -Wall -elf2flt -o test test.c
[root@localhost uClinux-dist]#cp ./test ./romfs/bin/
生成文件系统映像 直接执行下面的命令生成文件系统映像romfs.img：
[root@localhost uClinux-dist]#genromfs -v -V "ROMdisk" -f ./images/romfs.img -d ./romfs
[root@localhost uClinux-dist]#make image
[root@localhost uClinux-dist]#make
这时再重新
[root@localhost uClinux-dist]#./skyeye -e ./linux-2.4.x/linux -c skyeye.conf
就可以看到我们输入的信息了：
