Mycroft Mark2 GUI using system QT5 and KDE framework

This is based on the very helpful build log of user AIIX that he published on https://github.com/AIIX/Documentation/blob/master/Custom-RPI4-MycroftImage.md He is doing this on Rasbperry 4 while the target here is Raspberry 3B but also on 64-bit.

Install Linux

I tried to do this on Ubuntu 20.04 but failed to bring the SDDM up so I switched back to 18.04 https://github.com/TheRemote/Ubuntu-Server-raspi4-unofficial/releases/download/v28/ubuntu-18.04.4-preinstalled-server-arm64+raspi4.img.xz Flash it to sdcard and boot. After first boot login as ubuntu/ubuntu (takes a while until you can do this), change password

Wifi

ls /sys/class/net

on RP3 the wifi interface is the wlan0

sudo nano /etc/netplan/50-cloud-init.yaml

# network: {config: disabled}
network:
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    version: 2
    wifis:
        wlan0:
            optional: true
            access-points:
                "ESSID-of-the-Accesspoint":
                    password: "your-password"
            dhcp4: true

Remark: After SDDM is using NetworkManager I had to remove the wifis part otherwise wlan0 was unavailable

user

sudo useradd mycroft -g users -G sudo -m -s /bin/bash
sudo passwd mycroft
sudo nano /etc/group

(add mycroft to all groups like ubuntu)

From now on work as user mycroft

update / initial apt setup

sudo apt-get update && sudo apt-get dist-upgrade -y
sudo apt install git gnupg wget curl apt-transport-https software-properties-common

Do the next steps as root:

sudo su -

Add KDE Neon gpg key:

wget -qO - 'http://archive.neon.kde.org/public.key' | sudo apt-key add -

Add the repository

echo "deb https://archive.neon.kde.org/unstable focal main" > /etc/apt/sources.list.d/neon.list
sudo apt-get update

swap

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo nano /etc/fstab

add

/swapfile               none            swap    sw                              0 0

ramdisk

sudo mkdir /ramdisk
sudo nano /etc/fstab

add

tmpfs                   /ramdisk        tmpfs   rw,nodev,nosuid,size=20M        0 0

mycroft core

sudo apt-get install git python3 python3-dev python3-setuptools libtool libffi-dev libssl-dev autoconf automake bison swig libglib2.0-dev portaudio19-dev mpg123 screen flac curl libicu-dev pkg-config libjpeg-dev libfann-dev build-essential jq
cd ~
git clone https://github.com/MycroftAI/mycroft-core
cd mycroft-core
./dev_setup.sh -sm

mimic

skipped for now

wget http://frozenmazegames.se/mimic-arm64_1.2.0.2+1559651054-1.deb
sudo dpkg -i mimic-arm64_1.2.0.2+1559651054-1.deb

Plasma Nano

Install the system Libraries

I will try to come up with a completer list later but I think most of it should be in the dependencies of the following

sudo apt install sddm kwin-wayland kwin-x11 openssh-server ftp i2c-tools konsole nano plasma-workspace-wayland plasma-workspace plasma-pa plasma-widgets-addons libkf5wallet-bin gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-libav gstreamer1.0-fluendo-mp3 qml-module-qtmultimedia network-manager plasma-nm konsole plasma-workspace-dev

I was not asked for the login manager so I set it manually:

sudo dpkg-reconfigure sddm

build plasma-nano

sudo apt install cmake kwayland-dev
cd ~
git clone https://github.com/KDE/plasma-nano
cd plasma-nano
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -DKDE_INSTALL_LIBDIR=lib -DKDE_INSTALL_USE_QT_SYS_PATHS=ON
make -j 2
sudo make install

pi config.txt

# i2c on
dtparam=i2c_arm=on
# audio on
dtparam=audio=on

[all]
max_framebuffers=2
dtoverlay=vc4-kms-v3d
arm_64bit=1

enable i2c_dev

I did not have an /dev/i2c* device after booting only if I manually loaded i2c_dev so I did

sudo nano /etc/modules

add

i2c_dev

the i could use:

sudo i2cset -y 1 0x4b 30

to make the volume
