嵌入式gdb 问题

gdb 编译 host=arm-linux target=arm-linux

用该gdb去调试程序时，打印

嵌入式上调试不是KGBD么，X86和ARM是不一样的

你不会想用gdb 在target board上单步跟踪吧？

xiaokousky

就是在target board用gdb啊

xiaokousky

查阅gdb文档 终于找到一个有用的东西
set libthread-db-search-path [path]

T-Bagwell

gdb一般配合coredump来调试会好些，单步跟踪的话，还是不要在target board上跑了

如果需要在板子上用GDB调试，那还要一个gdbserver才行哦

正好路过问个问题：

gdbserver + xxx-linux-gdb调试时，有什么比较便捷的方法？
我现在每次都是
1 板子上跑起gdbserver
2 PC上xxx-gdb
3 target remote xxxxxx
每次敲命令有些烦，有什么好方可以简化2，3步，类似PC下的GDB一样？
