In this recipe, we will go through the several development workflows described previously using the U-Boot bootloader as an example.
We will see how the following development workflows are applied to U-Boot:
External development
External source development
Working directory development
Let's explain the three workflows, previously mentioned, in detail.
We will use a Yocto toolchain to build the U-Boot source externally from the Yocto build system.
Download and install a Yocto project cross-compilation toolchain for your host by going to the following:
http://downloads.yoctoproject.org/releases/yocto/yocto-1.7.1/toolchain/
Find the upstream Git repository:
$ bitbake -e u-boot-fslc | grep ^SRC_URI= SRC_URI="git://github...
