OTA Upgrade

Airbox supports OTA software updates, allowing you to update to a new version of the SOPHON SDK. The default SDK version in the Resource Download section is v23.10.01.

You can check the current SDK software version using bm_version:

linaro@Airbox:~$ bm_version
SophonSDK version: v23.10.01
sophon-soc-libsophon : 0.5.0
sophon-soc-libsophon-dev : 0.5.0

Upgrade libsophon​

If your application requires a newer SDK version, you can update the SDK software using the OTA upgrade package. Here, we use SDK-23.09 LTS SP3 as an example to upgrade libsophon to 0.5.1.

  • Download the target SDK version from the SOPHGO official website and extract it to obtain SDK-23.09_LTS_SP3.

  • Open the sophon-img subfolder in the SDK directory, and copy the bsp_update.tgz and system.tgz files to Airbox (e.g., to /home/linaro).

  • Extract bsp_update.tgz on Airbox and execute the upgrade script:

    tar zxvf bsp_update.tgz
    cd bsp_update
    sudo ./bsp_update.sh

  • Navigate back to the directory where system.tgz is located and extract its contents into the /opt/sophon/libsophon-0.5.0 directory:

    sudo tar xzf system.tgz -C /opt/sophon/libsophon-0.5.0
    sudo sync

  • After rebooting, verify whether libsophon has been successfully upgraded using bm-smi.

(Optional) Upgrade sophon-mw​

If your application requires a newer version of sophon-mw, you can install the updated .deb packages included in the latest SDK. Here, we use SDK-23.09 LTS SP3 as an example to upgrade sophon-mw to version 0.12.0.

  • Copy the sophon-mw-soc-sophon*.deb files from the SDK sophon-mw directory to Airbox (e.g., to /home/linaro).

  • Uninstall the current version of sophon-mw:

    sudo apt remove sophon-mw-soc-sophon-ffmpeg
    sudo apt remove sophon-mw-soc-sophon-opencv

  • Install the new version of sophon-mw:

    sudo dpkg -i ./sophon-mw-soc-sophon-ffmpeg_0.12.0_arm64.deb
    sudo dpkg -i ./sophon-mw-soc-sophon-opencv_0.12.0_arm64.deb

  • Check the sophon-mw version using bm_version:

    linaro@Airbox:~$ bm_version
    SophonSDK version: v23.10.01
    sophon-soc-libsophon : 0.5.0
    sophon-soc-libsophon-dev : 0.5.0
    sophon-mw-soc-sophon-ffmpeg : 0.12.0
    sophon-mw-soc-sophon-opencv : 0.12.0
