This is a list of known issues and limitations for Digi Embedded Yocto 5.0-r2:

  • Firmware update

    • The software update package must be located in the root level of the update media (subfolders are not yet supported).

  • ConnectCore Cloud Services

    • Remote file system management only supports names and paths up to 255 characters.

  • Mouse input does not work in Flutter-based applications. When launching Flutter applications, the system fails to register mouse input. This prevents interaction with graphical elements and UI components, impacting use cases that rely on pointer input. Using a panel with a touchscreen prevents the issue from appearing. This issue has been reported to the community, and we are waiting for a fix.

  • Mouse clicks stop working in WebKit after running the Aquarium demo or video settings icon. After executing the Aquarium WebGL demo in WebKit, mouse click events are no longer recognized in subsequent browsing sessions. An application restart is required to recover proper mouse functionality. This issue has been reported to the community, and we are working together on a fix.

  • Recipes with large downloads may fail during fetch operation due to timeout.

    Bitbaking an image recipe implies downloading and building the source code of all the recipes that form part of the root file system, which takes several hours the first time. Some source code repositories, such as the Linux kernel, represent a large download that might time out and make your build process fail. If this happens, run the following command to just fetch the source code of the offending recipe separately (to dedicate all CPU resources to it):

    $ bitbake -k --runall=fetch <image-recipe>

    When this task finishes successfully (you may need several retries), you can proceed to build your image recipe. Do the same with any recipe that fails with a timeout during the fetch operation.

ConnectCore MP25 SOM

  • Wireless

    • Performance of the wireless interface is reduced when using concurrent mode, as the wireless interface is shared between several different functionalities.

    • When using wireless concurrent mode, Digi recommends you keep the different modes on the same frequency channels. For example, when configuring access point mode on channel 36 in the 5GHz band, connect to the same channel both in station mode and Wi-Fi direct so that the radio performance is optimized.

    • When working as an access point, DFS-capable channels in the 5GHz band are not supported.

  • The boot artifacts from dey-4.0 cannot boot a dey-5.0 system.

  • USB 3.0 Type-C wire orientation detection is not supported yet; only one side works by default.

  • MMC0 input/output errors may appear during extended suspend/resume cycles.

  • The system may fail to power off correctly, eventually falling back to a watchdog reset.

ConnectCore MP25 Development Kit

  • The pinout on ConnectCore MP25 Development Kit DVK versions 1-4 is mirrored compared to standard pinout. For these boards, you must create a custom adapter to connect the debugger. To find out which board version you have, refer to Carrier board version and ID.
