推荐答案

您已阅读以下内容: https://www.kernel.org/pub/linux /kernel/people/jwessel/kgdb/ch03s04.html ?

Have you read this: https://www.kernel.org/pub/linux/kernel/people/jwessel/kgdb/ch03s04.html ?

您必须运行带有特殊选项的调试内核-例如:

You have to run debugged kernel with special options - like for example:

kgdbwait kgdbcon kgdboe=@192.168.248.76/,@192.168.242.24/00:11:22:33:44:55

在调试方面，您运行以下命令:

and on debugging side you run following commands:

gdb
file vmlinux
target remote udp:192.168.248.76:6443

对我有用.
