This is pre-release software and not intended for general use.
Aarch64 Quickstart Guide
This page will help those new to aarch64 (ARMv8) get started with the Foundation Model provided by ARM. The F21-20140628-foundation-v8 Remix tarball provides an F21-based disk image, which boots the kernel from the image using UEFI(Tianocore) and Grub2, and a sample script for starting the model. This Fedora Remix uses a look aside repository for the kernel package, which includes patches that are headed upstream, but not yet added to Fedora.
Download the Foundation Model
The first step is to download the Foundation model from ARM. The model is not re-distributable and will therefore require you to create a free account with ARM. Once completed, you will be able to download the Foundation Model and begin. NOTE - It is important to use the latest Foundation Model, if you encounter any issues check to see that you have the most recent version.
To run the model you may need to install some additional software with the following command:
sudo yum install xterm xorg-x11-fonts-{misc,100dpi,75dpi}* telnet bridge-utils
Extract the Foundation Model
Once you have downloaded the model, you will need to set up your environment. The model can be extracted to a path of your choosing. Your home directory will be used in this example.
Unpack the model:
mkdir ~/aarch64 cd ~/aarch64 tar xvzf FM000-KT-00035-r0p8-52rel06.tgz
Using the Model with an Image
Using the commands below, download and extract the Aarch64 root filesystem tarball.
cd ~/aarch64 wget http://dmarlin.fedorapeople.org/fedora-arm/aarch64/F21-20140628-foundation-v8.tar.xz tar xvf F21-20140628-foundation-v8.tar.xz
Allowing the Model to Connect to the Internet
On the host:
- Enable IP forwarding (as root)
echo 1 > /proc/sys/net/ipv4/ip_forward
- Set up Network Address Translation:
HOSTEXTERNAL=eth0 # Replace this with your outside interface sudo iptables -t nat -I POSTROUTING -o $HOSTEXTERNAL -j MASQUERADE sudo iptables -I FORWARD -i $HOSTEXTERNAL -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT sudo iptables -I FORWARD -i ARM1 -o $HOSTEXTERNAL -j ACCEPT
- Firewall trouble? Try this:
sudo iptables -I INPUT -i ARM1 -j ACCEPT
The model uses Google's Public DNS server (8.8.8.8) for name resolution (/etc/resolv.conf).
Starting the Model
The kernel supports virtio, so the kernel image and initramfs included on the image will be used in the boot process. This image boots using UEFI (tianocore) and Grub2.
An example script for starting the model has been included in the tarball. This script performs the following steps to start the model:
sudo ../Foundation_v8pkg/models/Linux64_GCC-4.1/Foundation_v8 \
--cores=1 \
--visualization \
--image=linux-system-el3-foundation.axf \
--data=RTSM_VE_FOUNDATIONV8_EFI.fd@0xA0000000 \
--block-device `pwd`/${IMAGE} \
--network=bridged \
--network-bridge=ARM1 &
sleep 5
sudo ifconfig ARM1 192.168.1.1 netmask 255.255.255.0
Depending on your environment you may need to change the IP addressing used.
To start the model, change to the image subdirectory and run the script:
cd ~/F21-20140628-foundation-v8 ./efi-aarch64.sh
You must have 'sudo' access in order to run this script. The script assumes the foundation model is in:
~/aarch64/Foundation_v8pkgAdjust as necessary for your environment.
To connect to the serial console, telnet to the provided ports as it boots, for example:
telnet 192.168.1.1 5000 # note this is the IP of the model gateway and not the model
Connecting using telnet will also close the xterm popup window.
This is an example log of the model starting, and using telnet to access the console:
terminal_0: Listening for serial connection on port 5000 terminal_1: Listening for serial connection on port 5001 terminal_2: Listening for serial connection on port 5002 terminal_3: Listening for serial connection on port 5003 Visualization web server started on port 2001 Simulation is started sh: xterm: command not found telnet 192.168.1.1 5000 $ telnet 192.168.1.1 5000 Trying 192.168.1.1... Connected to 192.168.1.1. Escape character is '^]'.
The model will then start the first stage bootloader (tianocore), which will launch grub2, which will in turn boot the selected kernel, for example:
To navigate the menu use '<ctrl>n' - next and '<ctrl>p' - previous.

You should be able to ssh to the model once it has fully booted.
It may take several minutes for the model to be fully booted.
- For ssh login:
ssh root@192.168.1.5 # note this is the IP address of the model
Notes:
- Verify that the system date/time are correct.
- To avoid image or filesystem corruption it is important to shutdown the model properly.
shutdown -h now
- After shutting down, ensure the Foundation Model process has been stopped before restarting.
sudo kill -TERM <PID for the Foundation Model process>
- The root password is 'fedora'.
