+# Image setup
+Guide to a manual image setup.
+
+
+## 1. The image
+Use Pi Imager to setup a base image. I used the username `oa` for this.
+
+
+## 2. Base requirements
+1. Setup increased swap space to avoid compile errors:
+```bash
+dphys-swapfile swapoff
+sed -i 's/CONF_SWAPSIZE=100/CONF_SWAPSIZE=1024/g' /etc/dphys-swapfile
+dphys-swapfile setup
+dphys-swapfile swapon
+```
+2. `apt-get update`
+3. Run the `setup_deps.sh` and `setup_runtime.sh` scripts.
+4. Setup Pipewire for audio:
+```bash
+apt-get install -y pipewire-audio pipewire-pulse pipewire-alsa
+```
+5. Setup udev rule
+```
+echo "SUBSYSTEM==\"usb\", ATTR{idVendor}==\"*\", ATTR{idProduct}==\"*\", MODE=\"0660\", GROUP=\"plugdev\"" | sudo tee /etc/udev/rules.d/51-openauto.rules
+```
+6. Install i2c headers for SWC (i2c-tools is useful for debugging)
+```bash
+apt-get install -y i2c-tools
+```
+
+
+## 3. Openauto
+Either clone/build or cross compile and copy the files over. Place them into `/home/oa/autoapp`.
+
+
+### 4. Enable auto login and start
+1. Hush login by doing `touch ~/.hushlogin`.
+2. Turn off login messages and enable auto login by changing `/etc/systemd/system/getty@tty1.service.d/autologin.conf`.
+```text
+ExecStart=-/sbin/agetty --skip-login --nonewline --noissue --autologin oa --noclear %I $TERM
+```
+3. Enable autostart as a user service (`systemctl --user enable /home/oa/openauto/autoapp.service`)
+```ini
+[Unit]
+Description=Openauto application.
+
+[Service]
+Type=simple
+WorkingDirectory=/home/oa/openauto
+ExecStart=/home/oa/openauto/autoapp --platform eglfs
+Restart=always
+
+[Install]
+WantedBy=default.target
+```
+4. Remember to enable GPIO 26 for enabling the amps
+
+
+## Bootup speed improvements
+1. Edit the `config.txt` file with the following changes:
+```txt
+dtoverlay=vc4-fkms-v3d
+gpu_mem=256
+
+boot_delay=0
+initial_turbo=30
+start_cd=1
+dtoverlay=sdtweak,overclock_50=100
+
+disable_splash=1
+dtparam=i2c_arm=on
+dtoverlay=pi3-disable-wifi
+
+avoid_warnings=1
+```
+2. Edit the `cmdline.txt` file with the following changes:
+```text
+console=tty1 root=xxxxxxx rootfstype=ext4 elevator=noop fsck.mode=skip fsck.repair=yes rootwait quiet logo.nologo loglevel=0 noswap plymouth.ignore-serial-consoles consoleblank=0 ipv6.disable=1 cfg80211.ieee802 cfg80211.ieee80211_regdom=AU
+```
+3. Turn of unncessary services. You may have to edit this list by using `systemd-analyze blame`
+```bash
+systemctl disable dphys-swapfile.service
+systemctl disable systemd-timesyncd.service
+systemctl disable ModemManager.service
+systemctl disable NetworkManager-wait-online.service
+systemctl disable udisks2.service
+systemctl mask systemd-rfkill.service           # hw button for wifi
+systemctl mask systemd-rfkill.socket
+systemctl disable triggerhappy.service          # joystick stuff or something on /dev/input/
+systemctl disable triggerhappy.socket
+systemctl disable raspi-config.service          # reenable if using some options in raspi-config
+systemctl mask rc-local                         # if not using /etc/rc.local
+systemctl disable sshswitch.service             # raspi enable ssh if file in boot
+systemctl disable rpi-eeprom-update.service     # applies a bootloader update if available
+systemctl disable keyboard-setup.service        # keyboard locale stuff
+systemctl disable e2scrub_reap.service
+systemctl disable console-setup.service
+systemctl disable avahi-daemon.service
+systemctl disable fake-hwclock.service
+systemctl mask systemd-journal-flush.service
+sysetmctl mask systemd-fsck-root.service
+```
+4. Change SSH to not use DNS in `/etc/ssh/sshd_config`
+
+
+
+
+## Wireless Setup
+1. Set wifi regulatory domain via `raspi-config`
+2. Setup hotspot via nmcli
+```bash
+nmcli con delete preconfigured
+nmcli con delete hotspot
+nmcli con add type wifi ifname wlan0 mode ap con-name hotspot ssid openauto autoconnect true
+nmcli con modify hotspot 802-11-wireless.band a
+nmcli con modify hotspot 802-11-wireless.channel 165
+nmcli con modify hotspot ipv4.method shared ipv4.address 192.168.4.1/24
+nmcli con modify hotspot ipv6.method disabled
+nmcli con modify hotspot wifi-sec.key-mgmt wpa-psk
+nmcli con modify hotspot wifi-sec.psk "xxxxxx"
+nmcli con modify hotspot wifi-sec.pmf 1
+nmcli con up hotspot
+```
+3. Add the corresponding lines to `openauto.ini`
+```ini
+[WiFi]
+SSID=openauto
+Password=xxxxxx
+```
+4. Pair and trust the phone via `bluetoothctl`
+
