#dbct:state=on 这么看来，是你的vmlinux 在pc为0x30108188指令上 访问了 0x0地址。
1、访问0地址是正确的，在skyeye.conf中配置上0地址。
2、访问0地址是错误的，跟踪汇编为何访问0地址。
建议先按第一种方案 试试，能不能跑过去。 我使用skyeye1.3.5运行了 s3c2440的测试用例，的确也有类似问题，但是不影响启动运行，具体内核为什么访问0地址，我还没有深入研究，如下是我的运行信息

重复打印了很多这个调试信息，可能淹没了串口输出信息。
你可以在skyeye.conf中，将串口输出方式改为term模式，如附件
最终进入linux的shell，但是shell无法输入。
