i used command "flex-builder -c linux:custom -a arm64" Configuring the kernel,,,What should I do if I want to revert to the original configuration
Please go to folder flexbuild_lsdk2012/build/linux/linux/arm64/LS/output/LSDK-20.12-V5.4, backup .config file and use the attached .config_bak to replace it.
You also could try the following method.
Remove Linux Kernel build folder flexbuild_lsdk2012/build/linux/linux/arm64/LS/output/LSDK-20.12-V5.4
and run the following command again.
flex-builder -c linux -a arm64
