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.

Installing Nim on Windows

What is Nim?

Nim is a (pretty obscure) "statically typed compiled systems programming language". It's unique because the syntax is very reminiscent of Python, while being a compiled language (; anyone?), hence making it accessible to Python devs. Now let's cut to the chase - how to install this:

Installing Nim

Method 1: The boring:tm:

(Powershell only)

1. Install chocolatey
2. choco install nim

absolute_mouse = usb_hid.Device(

        # Absolute mouse
        (0x05, 0x01)    # Usage Page (Generic Desktop)
        + (0x09, 0x02)  # Usage (Mouse)
        + (0xA1, 0x01)  # Collection (Application)
        + (0x09, 0x01)  # Usage (Pointer)

Docker on Android 🐋📱

Edit 🎉

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.
