This is a list of known issues and limitations for Digi Embedded Yocto 4.0-r5:

  • 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.

i.MX6QP system-on-chip

  • NXP i.MX6 processor has a documented errata (ERR004512) whereby the maximum performance of the Gigabit FEC is limited to 400Mbps (total for Tx and Rx).

ConnectCore 6 Plus 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 QCA6564 wireless chip does not support Wake On Wireless LAN.

    • For P2P connections, Digi recommends "Negotiated GO" modes. The ConnectCore 6 Plus fails to join autonomous groups.

ConnectCore 6 Plus SBC

  • The Micrel PHY KSZ9031 may take between five and six seconds to auto-negotiate with Gigabit switches.
