A X-Test Snap for Arm64/hf

This snap currently supports ubuntu-core 20/22 with optee 3.14 to 3.22 with arm64. We are still working on armhf.

Build

You can simply run ./run.sh build to build the snap, but you need to prepare the relevant build environment, such as arm64 Debian source. The script below can help you do that, but use it at your own risk.

CROSS_ARCH=arm64
if [ "$(dpkg --print-foreign-architectures | grep -c $CROSS_ARCH)" -ne 1 ] ; then
    sudo dpkg --add-architecture $CROSS_ARCH
    sudo sed -i 's/^deb \(.*\)/deb [arch=amd64] \1/g' /etc/apt/sources.list
for f in $(ls /etc/apt/sources.list.d/*.list); do
    sudo sed -i 's/^deb \(.*\)/deb [arch=amd64] \1/g' \$f
done
for f in $(ls /etc/apt/sources.list.d/*.sources); do
    echo "Architectures: amd64" | sudo tee -a \$f
done
fi
