RUN ON YOUR MACHINE

Prepairing your machine to run ARM binaries

Install qemu-static

dnf install qemu-user-static
systemctl restart systemd-binfmt

Mount the rootfs

Find the partition offset

parted sd-blob-b01.img
> unit B
> p

• Take note of the start position of the rootfs

Mount the root filesystem and some necessary virtual filesystems, then chroot

mount -o loop,offset=12582912 sd-blob-b01.img /mnt
cd /mnt

# The following might be needed, at least if you get "/bin/bash: no such file or directory" on chroot
cp /usr/bin/qemu-aarch64-static usr/bin/

mount -t proc proc proc/
mount -t sysfs sysfs sys/
mount -t devtmpfs devtmpfs dev/
mount -t devpts devpts dev/pts/

chroot ./

RUN ON THE JETSON ROOTFS

Automated setup

Set a temporary DNS server, will get overwritten when full system is running

echo nameserver 8.8.8.8 > /etc/resolv.conf

Install ansible

apt update
apt upgrade
apt install python3-pip
pip3 install ansible

Download this repo and run

git clone https://github.com/castortut/jetson-setup
cd jetson-setup
ansible-playbook customization.yaml

Donkeycar

Upgrade packages and install some tools and libraries we'll need later on

apt install libjpeg-dev libhdf5-dev libfreetype6-dev
pip3 install virtualenvwrapper

The rest we run as the jetson user:

su - jetson

set up the virtualenv

echo "export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3" >> .bashrc
echo "source /usr/local/bin/virtualenvwrapper.sh" >> .bashrc
source .bashrc

mkvirtualenv donkey1
echo "workon donkey1" >> .bashrc
source .bashrc

Install donkeycar

cd
git clone https://github.com/castortut/donkeycar.git
cd donkeycar
git checkout master

It is recommended to find a set of wheels (prebuilt binaries) for the libraries with binary extensions and install them before running the following

pip install -e .[nano]
pip install matplotlib

Download mycar

cd
git clone https://github.com/castortut/donkey_mycar.git mycar; 
cd mycar

POST FIRST-BOOT

This requires more space than the 12GB image has left so do it after copying to an SD card and resizing the filesystem:

pip install --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v42 tensorflow-gpu==1.14.0+nv19.9
