编译kernel之后安装重启没有生效，还是旧的内核版本。

我使用这个步骤：

编译成功内核后，并生成了deb安装包：

-rw-r–r-- 1 rock root 1190052 Nov 4 15:18 linux-libc-dev_5.10.66-10-rockchip_arm64.deb

使用如下命令安装：
dpkg -i linux-image-5.10.66-10-rockchip-gc428536281d6-dbg_5.10.66-10-rockchip_arm64.deb

安装完成后没有错误提示，extlinux.conf也有更新：

但是重启后仍然是旧的内核版本，不知道是否我操作的有问题？

接一个串口看看，看看启动的时候，选的是哪个内核。

Attach a serial console and check which kernel is loading during the boot.

#3

有具体的log提示吗？uboot的log怎么全部打开呢？

#4

你编译出来的内核版本是5.10.66-10，但你extlinux里面5.10.66-27仍然是第一位，所以默认会启动这个老内核

你把对应的启动项移到最前就可以了

#5

我试过改变启动顺序，但是还是不行，启动的仍是旧的内核版本：

#timeout 10
#menu title select kernel

我尝试将27改为30，比27更大的数字后，启动还是旧的内核，目前不知道什么原因？
