skyeye gdb单步调试问题
请问如何用gdb远程调试skyeye中的linux内核我的linux内核是按这个贴子编出来的"成功编译2_6_14 并在skyeye1_2_4上运行的步骤--并成功 mount nfs - Skyeye项目专栏 - 中国Linux公社论坛"
然后用skyeye -e vmlinux -d
运行内核。
再开一个终端
localhost linux-2.6.14]$ gdb

(gdb) target remote:12345
Remote debugging using :12345
0x00000000 in ?? ()
(gdb)
这时如果输入c可以正常运行起来。像这样
(gdb) c
Continuing.
Program received signal SIGTRAP, Trace/breakpoint trap.
0xc0ffd7d4 in ?? ()
(gdb)
但是我要怎么单步运行呢？怎么看运行到哪里了呢？
输入s,si好像都不行，如下：
(gdb) s
Cannot find bounds of current function
(gdb) si
0xc0ffd7d4 in ?? ()
(gdb) si
0xc0ffd7d4 in ?? ()
(gdb) si
0xc0ffd7d4 in ?? ()
(gdb) 各位老大，指点一下吧 http://www.linuxfans.org/bbs/thread-181087-1-1.html 非常感谢ksh
