Summary

The toolchain is always your starting point; everything that follows from that is dependent on having a working, reliable toolchain.

You may start with nothing but a toolchain—perhaps built using crosstool-NG or downloaded from Linaro—and use it to compile all the packages that you need on your target. Or you may obtain the toolchain as part of a distribution generated from source code using a build system such as Buildroot or the Yocto Project. Beware of toolchains or distributions that are offered to you for free as part of a hardware package; they are often poorly configured and not maintained.

Once you have a toolchain, you can use it to build the other components of your embedded Linux system. In the next chapter, you will learn about the bootloader, which brings your device to life and begins the boot process. We will use the toolchain we built in this chapter to build a working bootloader for the BeagleBone Black.
