[英]Why does my initramfs not detect init
我正在从minimalfs编译一个initramfs,它在启动期间无法检测到init。 我有2个simlink,一个在/ init,另一个在sbin / init,都指向/sbin/init.sysvinit
我只是尝试在内核配置中传递文件系统目录以及cpio。 以下是bootlog的结尾:

以下是我的bootargs:
“ console = $ {console} earlyprintk = serial mem = 128m”
我使用的硬件是基于am335x的定制板,它是特定于产品的beagle bone的完整定制版本。 具有128MB DDR内存。
初始化是一个elf二进制文件,其中链接有动态库。 我在初始化文件上使用readelf -d找到了它。 因此,我需要添加我认为可以在init中静态链接的libc库。 非常感谢“那个家伙”。
