我正在尝试在 raspberry pi 4b 上从源代码构建内核 uname -a 显示
Linux ubuntu-pi-kit 5.13.0-1025-raspi #27-Ubuntu SMP PREEMPT Tue Apr 5 12:08:41 UTC 2022 armv7l armv7l armv7l GNU/Linux
我下载了内核源代码
fakeroot apt-get source linux-image-$(uname -r)
内核已构建，但当我尝试安装它时，似乎存在版本错误，例如内核模块
/kernel/linux-raspi-5.13.0$ sudo make install
然后出现错误
sh ./arch/arm/boot/install.sh "5.13.19" \
arch/arm/boot/Image System.map "/boot"

当我编译内核时，确实花费了大量时间来编译内核模块。
好的，我发现我需要添加 make_install，如下所示
sudo make modules_install install
烧毁模块并将其放置在正确的位置。但是 dtb 文件仍然缺失。
任何帮助均感激不尽。
