Chapter 7: Developing with Yocto
Bringing up Linux on unsupported hardware can be a painstaking process. Luckily, Yocto provides Board Support Packages (BSPs) to bootstrap embedded Linux development on popular single-board computers such as the BeagleBone Black and Raspberry Pi 4. Building on top of an existing BSP layer lets us quickly take advantage of complex built-in peripherals such as Bluetooth and Wi-Fi. In this chapter, we will create a custom application layer to do just that.
Next, we will look at the development workflow that's enabled by Yocto's extensible SDK. Modifying software running on a target device usually means swapping out the SD card. Since rebuilding and redeploying full images is too time-consuming, I will show you how ...
