linux加载驱动出现can't change directory to

培风

按照教程modprobe chrdevbase.ko 加载驱动提示我打不开一个带后缀的文件夹，我新建了一个提示的文件夹倒是可以操作了，但是我明明是在4.1.15里面操作的，为什么会出现这个问题

/lib/modules/4.1.15 # modprobe chrdevbase.ko
modprobe: can't change directory to '4.1.15-g52f6b26': No such file or directory
/lib/modules/4.1.15 # cd ../
/lib/modules # mkdir 4.1.15-g52f6b26
/lib/modules # ls
4.1.15           4.1.15-g52f6b26
/lib/modules # cd 4.1.15-g52f6b26/
/lib/modules/4.1.15-g52f6b26 # modprobe chrdevbase.ko
modprobe: can't open 'modules.dep': No such file or directory
/lib/modules/4.1.15-g52f6b26 # ls
chrdevbase.ko  chrdevbaseApp
/lib/modules/4.1.15-g52f6b26 # modprobe chrdevbase.ko
modprobe: can't open 'modules.dep': No such file or directory
/lib/modules/4.1.15-g52f6b26 #

问题解决了，原来是我加载的内核跟我编译驱动指定的内核不一样，我把编译驱动指定的内核拷贝到tftpBoot下重新加载就可以了

我再用modprobe加载驱动会报错如下
/lib/modules/4.1.15-g52f6b26 # ls
chrdevbase.ko    modules.alias    modules.symbols
chrdevbaseApp    modules.dep
