how to revert back to default settings of make menuconfig

Question

I am using ridgerun sdk..I made some settings in the config file through the command "make menuconfig"(but now i dont remember what settings i made). Now I want to cancel those settings in the config file and want the default settings. But the command "make mrproper" is not supported by Ridgerun sdk.Please suggest some solution for this.

Answer 1

假设RidgeRun SDK使用Linux内核的kbuild的一些衍生物然后删除（当然首先确保备份它！）构建系统的根文件夹中的.config文件将起作用。

Answer 2

先前的配置文件重命名为.config.old只需将其复制到较新的配置文件上.config.old

cp .config.old .config
