迅为iMX6开发板-设备树内核-menuconfig的使用
2020-11-06 22:06:00 【书白】
本文档主要讲解在 iMX6 开发板设备树的 menuconfig 的用户。
注意,关于 menuconfig 的操作,具体可以参考用户手册 9.3 小节,本文档主要介绍如何调用出 menuconfig 界面。
如下图所示,是 imx6q 的设备树内核源码目录,plus 和 imx6d 的类似。

要开启 menuconfig,要用到.config 文件,设备树内核的.config 文件,需要配置下,如下图所示。
android 的缺省文件是:arch/arm/configs/imx_v7_android_defconfig
qt 的缺省文件是:arch/arm/configs/imx_v7_linux_defconfig

使用命令“cp -r arch/arm/configs/imx_v7_linux_defconfig .config”,配置拷贝缺省文件到内核目录,然后使用命令“export ARCH=arm”设置为 arm 平台,如下图所示。

接着使用命令“make menuconfig”就可以打开 menuconfig 文件,如下图所示。

关于 menuconfig 界面的操作,可以参考用户手册 9.3 小节。如果需要在 menuconfig中配置,可以将配置好的 .config 覆盖掉 imx_v7_linux_defconfig,这样重新编译内核就会使用新配置的.config 文件。
