    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
$ sudo ./sd_fusing_rpi3.sh -d /dev/sdb -b tizen-unified_20201007.2_iot-boot-armv7l-rpi3.tar.gz tizen-unified_20201007.2_iot-headed-3parts-armv7l-rpi.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.

      • 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 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.
