Aurora - RaspberyPi image

Setup environment

 sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
     build-essential chrpath socat cpio python3 python3-pip python3-pexpect \
     xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \

Initialize project

./init

Build for Raspberry Pi 4

. sources/poky/oe-init-build-env bitbake aurora

Build for QEMU(x86_64)

Change the MACHINE variable to qemux86-64 in ${BUILDDIR}/conf/local.conf
Run sources/poky/oe-init-build-env bitbake aurora

If you encounter any error at running the task do_package_write_rpm you can set the PACKAGE_CLASSES variable in ${BUILDDIR}/conf/local.conf to package_deb

To speed up the qemu image, one can enable virtualization: https://help.ubuntu.com/community/KVM/Installation

sudo apt-get install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
sudo adduser `id -un` libvirt
sudo adduser `id -un` kvm
log out/reboot

After that, one can tweak the parameters of the qemu virtual machine so that it has access to more memory/processing power/cpu features". For example: runqemu qemux86-64 qemuparams="-cpu max -smp $(nproc) -m 2048M -display sdl -machine type=q35,accel=kvm" For a bigger list of qemu features and other parameters, check: https://wiki.gentoo.org/wiki/QEMU/Options

Built images may be found in ${BUILDDIR}tmp/deploy/images/raspberrypi4/

Extract the new image: bzip2 -df aurora.wic.bz2

Find the coresponding device for the sdcard using: lsblk -p

Transfer the image to the sd-card using dd(Note: your of might be different. Pay close attention to the previous step.): dd if=aurora.wic of=/dev/mmcblk0 bs=4M conv=fsync status=progress
