Ubuntu Setup

Ubuntu has two issues which make the setup slightly more involved (but not that much more so). First is that the QEMU package is pretty outdated (we require 4.2+). Second is that Ubuntu has a GDB which can work on any architecture, rather than having a arch-specific one. We can address these issues by creating a file conf.mk and overriding some tool selections.

But first, install required packages like so:

sudo apt install qemu-system-arm build-essential gcc-arm-none-eabi \
    binutil-arm-none-eabi gdb-multiarch libpixman-1-dev gcovr python3

Also install pytest:

pip3 install --user pytest

QEMU Setup

First, check your installed Qemu version.

qemu-system-arm --version

If the version is >=4.2, then you're good! Proceed to the next section. Otherwise, you'll need to build and install version 4.2 or greater. These steps will download 4.2, compile it, and install it into your home directory:

wget https://download.qemu.org/qemu-4.2.0.tar.xz
tar xf qemu-4.2.0.tar.xz
cd qemu-4.2.0
./configure --target-list=arm-softmmu --prefix=$HOME/qemu-local
make -j8  # set the -j arg based on your system's CPUs
make install

Now, you can place the following into your conf.mk:

QEMU := $(HOME)/qemu-local/bin/qemu-system-arm

GDB Setup

Place the following into conf.mk to set the GDB version you'll use:

GDB := gdb-multiarch
