openwrt只编译kernel

本想只编译ko， ，结果搜索论坛发现要编译 kernel

https://forum.archive.openwrt.org/viewtopic.php?id=23570

用下面这个命令编译内核：

make target/linux/{clean,compile} V=s

修改 linux-4.4.18/drivers/net/ethernet/realtek/r8169soc.c 后

make target/linux/compile  V=s

拷贝到自定义路径下

cp linux-4.4.18/drivers/net/ethernet/realtek/r8169soc.ko files/evideo/

根据openwrt自定义文件配置，拷贝到files下的文件就会自动拷贝到对应目录

Custom files

In case you want to include some custom configuration files, the correct place to put them is:

• <buildroot>/files/

For example, let's say that you want an image with a custom /etc/config/firewall or a custom etc/sysctl.conf, then create this files as:

• <buildroot>/files/etc/config/firewall

• <buildroot>/files/etc/sysctl.conf

E.g. if your <buildroot> is ~/source and you want some files to be copied into firmware image's /etc/config directory, the correct place to put them is ~/source/files/etc/config.
