每次运行
make时
它开始编译，但随后停止，告诉我：

从配置中看，您编译的是i586，而不是arm或aarch64。
如果您键入make list-defconfigs，那么它将向您显示一个列表；摘录如下：
raspberrypi2_defconfig - Build for raspberrypi2
raspberrypi4_64_defconfig - Build for raspberrypi4_64
raspberrypi4_defconfig - Build for raspberrypi4
sheevaplug_defconfig - Build for sheevaplug
一旦你确定了你需要的defconfig，那么你就可以这样做：
make raspberrypi4_defconfig
并且它将初始化所选目标的基本配置。使用此配置，您的编译应该会一直运行到完成。
