This is a list of known issues and limitations for Digi Embedded Yocto 4.0-r6:

  • Firmware update

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

    • To update from dey-3.2 version or lower 4.0-r6 on a single boot layout, you must flash the recovery partition with the latest Yocto release before performing the firmware update.

  • ConnectCore Cloud Services

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

  • GPU maximum performance reduced. The maximum frequency targets are 850 MHz for the shaders and 700 MHz for the core. However, in this hardware release the maximum frequency is limited to 650 MHz for the shaders and 600 MHz for the core, with the corresponding performance reduction.

  • 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.
