Emulating Raspberry Pi 4 with Qemu

Just a quick update before we dive in: what we're actually doing here is running Raspberry Pi OS (64-bit) on a QEMU virtual ARM setup. This isn't full-blown hardware emulation of the Raspberry Pi 4, but more about creating a virtual environment for the OS. It doesn't mimic all the specific hardware features of the Pi 4, but it's pretty useful and great for general testing. I turned to this solution mainly to extract a modified sysroot from the Raspberry Pi OS, something not readily available in other resources. For those looking into detailed emulation of the actual Raspberry Pi 4's hardware in QEMU, check out this link for the latest updates: https://gitlab.com/qemu-project/qemu/-/issues/1208.

Hope it helps! :D

Shortcomings: No GUI yet, only console.

Steps

React Native Trouble

Updating to macOS Sierra is causing trouble with React Native due to some of the Node.js and system utilities it uses. Specifically the watch utility fails due to a limit on the number of files which can be opened at a time.

The following command shows the current limit.

launchctl limit maxfiles

TL;DR

Create 5GB FreeBSD image.
Install FreeBSD on xhyve.
Mount host directory.
