Hello,

Does anyone know how to setup buildroot to automatically configure
the kernel with allnoconfig and then apply my own customizations? For example:

cd output/build/linux-4.11.3

make KCONFIG_ALLCONFIG=custom.config allnoconfig

Thanks,

Stephen

cd output/build/linux-4.11.3
make KCONFIG_ALLCONFIG=custom.config allnoconfig

This is not possible today, it would require extended the kconfig-package infrastructure a bit.

What you can do today (obviously), is generate this kernel configuration, possibly by going in output/build/linux-4.11.3, save it as a defconfig that you then tell Buildroot to use. Not ideal perhaps, but it works :)

Best regards,

Thomas
