linux - 尝试启动新的 uImage

Question

我正在尝试通过 uboot 启动 uImage，但我得到了一些看似冲突的日志信息:

所以我的问题是:

有没有办法让我在构建内核时对其进行版本控制，我可以设置“镜像名称”，以便我知道正在加载我的内核而不是某种类型的旧镜像？

也许 Linux 内核 .config 文件的 CONFIG_LOCALVERSION 选项会对您有所帮助。

来自Kernel.org :

Keep a backup kernel handy in case something goes wrong. This is especially true for the development releases, since each new release contains new code which has not been debugged. Make sure you keep a backup of the modules corresponding to that kernel, as well. If you are installing a new kernel with the same version number as your working kernel, make a backup of your modules directory before you do a make modules_install.

Alternatively, before compiling, use the kernel config option “LOCALVERSION” to append a unique suffix to the regular kernel version. LOCALVERSION can be set in the “General Setup” menu.

因此，在内核配置期间，您可以向内核添加一些明确的后缀，例如CONFIG_LOCALVERSION="-test_some_stuff"。
