2 加载内核符号及源代码

设置符号及源代码路径

在上位机上下载符号文件和源代码并记住相应路径
下载符号文件：https://share.weiyun.com/cX4iGDRO

注意Ulan有SSD盘NVME和eMMC闪存卡上两个Ubuntu Linux系统5.10.110和6.1.115：https://www.cnblogs.com/rgqancy/p/19847942

注意：一定要启动nvme上的Ubuntu Linux系统5.10.110。NanoCode才能正常加载源代码。

[禁止RCU看门狗 - Powered by MinDoc](https://www.nanocode.cn/wiki/docs/youlan/rcudog)

在内核调试时，如果将内核中断下来停止太久，可能激活内核看门狗机制，引发内核崩溃，影响调试。
