Running AutoSD on Raspberry pi 4

Running AutoSD on Raspberry pi 4

The Automotive SIG publishes images built via OSBuild based on the OSBuild manifest present in the sample-images repository.

Here is a quick guide on how to get you started with them.

We recommend you start with the gadget image. See Sample OS images for more information about the available prebuilt images.

  1. Update eeprom.

    Note

    If eeprom is out-of-date, you might experience boot failures on Raspberry Pi 4 (rpi4). For more information about how to update eeprom, see the guide.

  2. Download your rpi4 image from https://autosd.sig.centos.org/AutoSD-9/nightly/.

  3. Unpack the image.

    console unxz auto-osbuild-rpi4-cs9-gadget-regular-aarch64-*.raw.xz

  4. Flash it onto your SD card.

    Important

    Change the block device, shown as /dev/disk0 in the example, according to your system.

    console sudo dd if=auto-osbuild-rpi4-cs9-gadget-regular-aarch64-*.raw of=/dev/disk0 status=progress bs=4M; sync

  5. Insert the SD card into your Raspberry Pi 4.

  6. Boot the Raspberry Pi 4.

  7. Connect the Raspberry Pi 4.

    Important

    Serial and WiFi are not yet functional.

    Connect to the Raspberry Pi 4 via a USB keyboard or via SSH with an Ethernet cable.

  8. Log in as root or guest using the password: password.

  9. Connect the Raspberry Pi 4 to the internet.

    • Option 1) Connect by using an Ethernet cable if you have one. This is the most simple solution.

    • Option 2) Enable the WiFi adapter on the Raspberry Pi 4:

      ```console

      dnf install -y NetworkManager-wifi

      systemctl restart NetworkManager

      ```

      List the surrounding WiFi SSIDs and connect to them:

      ```console

      nmcli dev wifi list

      nmcli --ask dev wifi connect

      ```

    • Option 3) If you are not near a router or cannot connect the Raspberry Pi by using an Ethernet cable, use the gadget image. For more information about how to use the gadget image, see USB gadget.

Enable Bluetooth

  1. To enable Bluetooth functionality, install some required packages:

    ```console

    dnf install NetworkManager-bluetooth

    systemctl restart NetworkManager

    ```

  2. Enable and start the service:

    ```console

    systemctl enable --now bluetooth

    ```

  3. List the available Bluetooth devices:

    ```console

    bluetoothctl list

    Controller AA:AA:AA:AA:AA:AA BlueZ 5.56 [default] ```

    Notice the MAC address of the device is listed as AA:AA:AA:AA:AA:AA. This is incorrect, and it indicates that some Linux firmware is missing.

    ```console

    cd lib

    grep -rni . -e firmware/ | grep brcm | grep dracut

    ./dracut/modules.d/62bluetooth/module-setup.sh:37: /lib/firmware/brcm/.hcd \

    ls /lib/firmware/brcm/

    'brcmfmac43430a0-sdio.ONDA-V80 PLUS.txt.xz' 'brcmfmac43455-sdio.MINIX-NEO Z83-4.txt.xz' 'brcmfmac43455-sdio.Raspberry Pi Foundation-Raspberry Pi 4 Model B.txt.xz' brcmfmac43455-sdio.acepc-t8.txt.xz brcmfmac43455-sdio.raspberrypi,3-model-a-plus.txt.xz 'brcmfmac43455-sdio.Raspberry Pi Foundation-Raspberry Pi Compute Module 4.txt.xz' brcmfmac43455-sdio.bin.xz brcmfmac43455-sdio.raspberrypi,3-model-b-plus.txt.xz brcmfmac43455-sdio.clm_blob.xz brcmfmac43455-sdio.raspberrypi,4-model-b.txt.xz ```

    Notice there are no *.hcd files for any Bluetooth firmware.

  4. Download the required firmware from GitHub:

    ```console

    cd ~

    git clone https://github.com/RPi-Distro/bluez-firmware/tree/master/broadcom

    cd bluez-firmware/broadcom

    cp *.hcd /lib/firmware/brcm/

    ```

  5. Reboot the system:

    ```console

    reboot

    ```

  6. List the available Bluetooth devices again to confirm that the device has a MAC address:

    ```console

    bluetoothctl list

    Controller DC:A6:32:B9:6A:DC BlueZ 5.56 [default] ```

  7. Start the device:

    ```console

    bluetoothctl

    power on Changing power on succeeded. ```

  8. Put a selected device, such as a controller or a portable speaker, in pairing mode so you can connect it to the Raspberry Pi 4.

  9. Scan for nearby Bluetooth devices:

    ```console

    scan on ... [NEW] Device F4:93:9F:63:7F:6C Wireless Controller ... ```

  10. Connect to the device:

    ```console

    connect F4:93:9F:63:7F:6C

    [bluetooth]# connect F4:93:9F:63:7F:6C Attempting to connect to F4:93:9F:63:7F:6C [CHG] Device F4:93:9F:63:7F:6C Connected: yes [CHG] Device F4:93:9F:63:7F:6C UUIDs: 00001124-0000-1000-8000-00805f9b34fb [CHG] Device F4:93:9F:63:7F:6C UUIDs: 00001200-0000-1000-8000-00805f9b34fb [CHG] Device F4:93:9F:63:7F:6C ServicesResolved: yes [CHG] Device F4:93:9F:63:7F:6C Paired: yes Connection successful ```

  11. After the device is connected, exit bluetoothctl:

    ```console

    exit ```
