Flash through the command line

You can flash the SD card through the command line on a Linux computer. To flash the SD card for Raspberry Pi 3 or 4, follow the steps below:

  1. Complete the following prerequisites:

    1. Install the pv package in the Linux computer:

      $ sudo apt-get install pv

    2. Ensure that you have an SD card of 8 GB or more.

    3. Verify whether the binary image files are in your computer.

    4. Fusing-script for Raspberry Pi 3 (fusing script is same for RPI3 and RPI4):

      $ wget https://git.tizen.org/cgit/platform/kernel/u-boot/plain/scripts/tizen/sd_fusing_rpi3.sh?h=tizen --output-document=sd_fusing_rpi3.sh
$ chmod 755 sd_fusing_rpi3.sh

  2. Flash the SD card to ensure it is ready to be used for Tizen:

    1. Insert an SD card to the Linux computer and verify its device node.

      Note

      To verify the device node:

      1. Run the following command before inserting the SD card into the Linux computer:

        $ ls -al /dev/sd*

        For example:

        $ ls -al /dev/sd*
brw-rw---- 1 root disk 8, 0  9 18 09:08 /dev/sda
brw-rw---- 1 root disk 8, 1  9 18 09:08 /dev/sda1
brw-rw---- 1 root disk 8, 2  9 18 09:08 /dev/sda2
brw-rw---- 1 root disk 8, 5  9 18 09:08 /dev/sda5

      2. Insert the SD card and type the same command again:

        $ ls -al /dev/sd*

        For example:

        $ ls -al /dev/sd*
brw-rw---- 1 root disk 8,  0  9 18 09:08 /dev/sda
brw-rw---- 1 root disk 8,  1  9 18 09:08 /dev/sda1
brw-rw---- 1 root disk 8,  2  9 18 09:08 /dev/sda2
brw-rw---- 1 root disk 8,  5  9 18 09:08 /dev/sda5
brw-rw---- 1 root disk 8, 16  9 22 14:59 /dev/sdb
brw-rw---- 1 root disk 8, 17  9 22 14:59 /dev/sdb1
brw-rw---- 1 root disk 8, 18  9 22 14:59 /dev/sdb2
brw-rw---- 1 root disk 8, 19  9 22 14:59 /dev/sdb3
brw-rw---- 1 root disk 8, 20  9 22 14:59 /dev/sdb4
brw-rw---- 1 root disk 8, 21  9 22 14:59 /dev/sdb5
brw-rw---- 1 root disk 8, 22  9 22 14:59 /dev/sdb6
brw-rw---- 1 root disk 8, 23  9 22 14:59 /dev/sdb7

        The new sdX node (where X is a letter) is the device node for the SD card.

        In this example, the device node for the SD card is sdb.

    2. Download compatible boot and platform image according to target device.

    3. Run the following commands:

      $ sudo ./sd_fusing_rpi3.sh -d <SD card device node> --format
$ sudo ./sd_fusing_rpi3.sh -d <SD card device node> -b <Boot Image path> <Platform Image path>

      For example:

      $ sudo ./sd_fusing_rpi3.sh -d /dev/sdb --format
$ sudo ./sd_fusing_rpi3.sh -d /dev/sdb -b tizen-unified_20221017.061100_tizen-boot-armv7l-rpi3.tar.gz tizen-unified_20221017.061100_tizen-headed-armv7l.tar.gz

  3. Open the Smart Development Bridge (SDB) connection. For more information, see Set up Raspberry Pi 3 or 4.

    Note

    Repeat sdb connect 192.168.1.11 in the Linux shell (Linux) or the command window (Windows) whenever you power cycle the device, in order to reconnect the SDB tool.

Set up Raspberry Pi 3 or 4

Connect the board to the PC

To configure the Raspberry Pi board, follow the steps below:

  1. Insert the SD card, in which Tizen IoT binaries and the drivers are flashed into the Raspberry Pi board.

  2. For the serial communication connection:

    1. Connect the host computer to the Raspberry Pi with a UART-to-USB dongle such as PL2303 or FT232 USB UART board.

      To use the PL2303, connect the Raspberry Pi TXD0 pin (pin 8) to RXD on the UART board, RXD0 (pin 10) to TXD on the UART board, and the ground (pin 6) to GND on the UART board, and set the jumper switch to 3.3V (pin 1).

      Note

      Before using a UART-to-USB dongle, familiarize yourself with any hardware limitations it has by visiting the manufacturer’s website.

    2. Execute a terminal program such as Minicom or PuTTY.

      • Minicom example:

        Minicom can be used in Linux computer. Run the following command to run Minicom:

        $ sudo minicom -c on

        To configure Minicom:

        1. Go to the Minicom configuration settings menu by consecutively pressing Ctrl + A, Z, and O (the letter O).
        2. In the Serial Device field, set the correct USB port for serial communication. The format is /dev/ttyUSBX where X equals the number of the port.
        3. Modify the Hardware Flow Control field to No.
        +-----------------------------------------------------------------------+
| A -    Serial Device      : /dev/ttyUSBX                              |
| B - Lockfile Location     : /var/lock                                 |
| C -   Callin Program      :                                           |
| D -  Callout Program      :                                           |
| E -    Bps/Par/Bits       : 115200 8N1                                |
| F - Hardware Flow Control : No                                        |
| G - Software Flow Control : No                                        |

        In the serial shell, log in with root/tizen:

        localhost login: root
Password: tizen
Welcome to Tizen

      • PuTTY example:

        Download PuTTY from the Internet and launch PuTTY.

        PuTTY Config

        To configure PuTTY, follow the steps below:

        1. Select Serial connection type.
        2. Enter the serial line number for the board connected to your computer (it can be COMN where N is a natural number such as COM1, COM4, and so on) in the Serial line field.
        3. Type 115200 in the Speed field.
        4. Click Open.

        In the serial shell, log in with root/tizen:

        localhost login: root
Password: tizen
Welcome to Tizen

  3. For the SDB connection:

    1. Connect the host computer to the Raspberry Pi through an Ethernet cable.

      Note

      If Ethernet ports are not available in the host computer or the Raspberry Pi, you can also use an Ethernet-to-USB dongle.

    2. Set a new network interface in the host computer as shown in the following figures. This is a one time activity:

      • Linux computer.

        Linux Network Configuration

      • Windows computer.

        Windows Network Configuration

      If you are using the Ethernet-to-USB dongle, you must install the proper driver for the dongle. If the network cable is connected correctly, you can find a new connection in Network and Sharing Center. In the new connection, enter the properties of IPv4, and configure as shown in the Windows computer figure.

  4. Verify the IP address for eth0.

    ifconfig

    If the IP address for eth0 is 192.168.1.11, go to step 5. If not, set an IP address for the SDB connection in the serial shell of the Raspberry Pi using the ifconfig command:

    ifconfig eth0 192.168.1.11

  5. Connect Smart Development Bridge (SDB) in the Linux shell (Linux) or Command window (Windows) of the host computer:

    sdb connect 192.168.1.11
sdb root on

    For example, for Linux computer:

    ~$ sdb connect 192.168.1.11
* server not running. starting it now on port 26099 *
* server started successfully *
connecting to 192.168.1.11:26101 ...
connected to 192.168.1.11:26101
~$ sdb root on
Switched to 'root' account mode
~$

  6. Enter the sdb help command in the Linux shell (Linux) or Command window (Windows) of the host computer, for more information.

    Note

    sdb execution file is available in the tools sub-directory of the directory where Tizen Studio is installed.

Install drivers

  1. Connect Smart Development Bridge (SDB) as described in Connect the board to the PC.
  2. Install the connectivity drivers for each board:
    • Raspberry Pi 3/4

      1. Download the plugin zip file from the Raspberry Pi 3/4(7.0) Plugin section at Tizen Device Firmware and follow the instructions.

      2. For the case of the Linux shell (Linux), run the sh script given in the instructions. For example:

        $ ./install_with_SDB.sh

Set up Wi-Fi

This section is not applicable if you want to connect your device to the SmartThings Cloud. In case of SmartThings devices, the device enables SoftAP mode during setup. Therefore, you need not switch to Wi-Fi separately.

You can set up a Wi-Fi connection by running wifi_manager_test and entering the options 1 > 3 > 9 > b > c. If you set up the connection once, it reconnects automatically the next time you power cycle the device.
