Re: 您好，关于1.3.5的段错误问题

[Michael.Kang]

好的。能否把你的hello发给我测试一下，二进制以及源代码。
另外你的系统是什么？

如果你愿意的话，可以在sourceforge上帮我们报一下bug, 链接如下：

我怀疑是我哪个库有问题，hello用的是testsuit的程序，只不过换到了S3C6410上。系统是ubuntu11.04

[Michael.Kang]

我测试了一下，如果用你所提到的s3c6410的配置文件运行测试用例的

arm_hello确实会有一个segment fault的错误，我已经报告到我們的错误
跟踪中，这是skyeye本身的一个问题。

另外，测使用例的 arm_hello是和skyeye.conf相关联的，也就是说测试用例
的arm_hello是写给s3c2410的。如果你要用s3c6410的skyeye配置去运行
arm_hello，你需要修改 arm_hello的源代码。建议你看一下我们在安装目录

/opt/skyeye/testsuite/arm_hello中的源代码，根据s3c6410的地址空间和串口
地址进行移植。
