http://blog.chinaunix.net/uid-26963688-id-3268312.html
开发环境:
Ubuntu 12.04 LTS
开发包:
skyeye-1.3.3_testsuite_rel.tar.gz

注:skyeye-1.3.3的安装见本博客http://blog.chinaunix.net/space.php?uid=26963688&do=blog&id=3267351帖子

测试步骤:
1. 解压skyeye-1.3.3_testsuite_rel.tar.gz,在终端运行 tar zxvf skyeye-1.3.3_testsuite_rel.tar.gz 命令,解压:
root@chaozang:/opt/skyeye_install_packets# tar zxvf skyeye-1.3.3_testsuite_rel.tar.gz 
解压完毕:

2.切换到skyeye-testsuite目录:
root@chaozang:/opt/skyeye_install_packets# cd skyeye-testsuite
其中u-boot是bootloader的相关程序,uClinux是不带MMU的linux内核文件,linux目录下是我们所需要的,即Linux内核相关,vxworks是另一个架构的实时内核。

3.我们首先采用s3c2440作为开发板,采用linux2.6.30.5内核:
root@chaozang:/opt/skyeye_install_packets/skyeye-testsuite/linux/s3c2440/2.6.30.5#

4.在该目录下运行linux内核镜像:
root@chaozang:/opt/skyeye_install_packets/skyeye-testsuite/linux/s3c2440/2.6.30.5# /opt/skyeye/bin/skyeye -e vmlinux 
终端将打印出如下信息,即启动skyeye:
root@chaozang:/opt/skyeye_install_packets/skyeye-testsuite/linux/s3c2440/2.6.30.5# /opt/skyeye/bin/skyeye -e vmlinux

ARMLinux for Skyeye

Enter 'help' for a list of built-in commands.

经过一段时间的等待,终于出现了令人心动的画面ARMLinux,由此可见,2.6.30.5内核已经正常的运行起来了。
同时可以看出skyeye比较消耗资源:
采用同样的方法,可以测试下uClinux:
