To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Creating Embedded Linux distros with the Yocto Project

Introduction

This guide is developed and tested using Ubuntu 16.04 as a host computer.

Installing Dependencies

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath libsdl1.2-dev xterm

Emulate Raspbian (Buster) with QEMU on macOS

Steps

Install qemu:
```
brew install qemu
```
Download qemu-rpi-kernel:

Running Ubuntu 16.04.1 armhf on Qemu

This is a writeup about how to install Ubuntu 16.04.1 Xenial Xerus for the 32-bit hard-float ARMv7 (armhf) architecture on a Qemu VM via Ubuntu netboot.

The setup will create a Ubuntu VM with LPAE extensions (generic-lpae) enabled. However, this writeup should also work for non-LPAE (generic) kernels.

The performance of the resulting VM is quite good, and it allows VMs with >1G ram (compared to 256M on versatilepb and 1G on versatile-a9/versatile-a15). It also supports virtio disks whereas versatile-a9/versatile-a15 only support SD cards via the -sd argument.
