With the help of SkyEye-1.2.0-RC7. DDD with arm-linux-gdb can remote debug linux kernel.
please see blow picture.

能贴一下 arm-elf-gcc 和arm-elf-gdb 的版本嘛？
为什么写了一个简单的带有调试信息的arm启动程序。 可以用skyeye启动。但是用arm-elf-gdb 调试的时候，总是有问题。
gdb会出现：
>Single stepping until exit from function begin,
>which has no line number information.
>Can't send signals to this remote system.SIGHUP not sent.
>
>Program received signal SIGHUP, Hangup.

info all-registers: 发现程序根本就没运行。

我得gcc，gdb版本

skyeye 启动信息。 为什么很多debug段没有被载入啊？ 是否跟这个有关系？
