1. List Available Defconfigs:
>
The make "list-defconfigs" command lists the available defconfigs
(configuration files) that you can use as a base for your system.
> These defconfigs define the default configuration options for different architectures and platforms.
2. Select a Defconfig:
> Choose a defconfig that matches your target architecture or platform.
> For example, if you’re using QEMU to emulate an x86_64 system, you can use the qemu_x86_64_defconfig.
3. Configure the System:
> Run make menuconfig to interactively configure your system.
>
This command opens a menu where you can select various options, such as
enabling specific packages, adjusting kernel settings, and customizing
your root filesystem.
4. Build the System:
> Finally, execute make to start the build process.
> Buildroot will compile the kernel, bootloader, root filesystem, and other components based on your configuration.
Create Raspberry Pi Image:
$ git clone https://github.com/buildroot/buildroot.git
Then go to build root path.
$ cd buildroot
$ make list-defconfigs | grep raspberry
$ make raspberrypi_defconfig
$ make menuconfig
$ make
$ ./buildroot/output/images/start-qemu.sh
