Known Issues and Limitations

This is a list of known issues and limitations at the time of release. An updated list can be found on the online documentation.

  • Firmware update
    • The software update package must be located in the root level of the update media (subfolders are not yet supported).
  • Cloud Connector
    • Remote file system management fails with long file names and paths (over 255 characters).
  • For P2P connections Digi recommends "Negotiated GO" modes. The QCA6564 devices (ConnectCore 6UL, ConnectCore 6 Plus) fail to join autonomous groups.
  • Trustfence is not yet supported on U-Boot v2018.03.

ConnectCore 8X

  • i.MX8QXP Processor
    • 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. These targets will be met in future releases of the hardware.
    • BSDL operation is not supported. It will be available in future releases of the hardware.
  • Digi Embedded Yocto
    • The following features are not supported in this release for the ConnectCore 8X platform:
      • Trustfence (TM)


IMPORTANT: This release updates the firmware of the System Control Unit (SCU). This is an NXP proprietary firmware and its last version is not compatible with the previous one released on DEY-2.6-r1. As a consequence:

  • Old U-Boot v2018.03-r1 cannot boot images from this release DEY-2.6-r2.
  • New U-Boot v2018.03-r2 cannot boot images from previous release DEY-2.6-r1.

To succesfully run DEY-2.6-r2 images you need to update the U-Boot on your device.


ConnectCore 6UL

  • ConnectCore 6UL System-on-Module (SOM)
    • The UART connected to the Bluetooth chip on early versions of the ConnectCore 6UL system-on-module (hardware version < 4) cannot properly execute flow control. To work around this issue, UART1 of these SOM versions has been configured to operate at 115200 bps and without hardware flow control, reducing the maximum throughput of this interface.
    • When using wireless concurrent mode as the wireless interface is shared between several different functionalities performance is reduced.
    • When using wireless concurrent mode Digi recommends to keep the different modes on the same frequency channels. For example, when configuring access point mode on channel 36 on band A, the recommendation would be to connect to the same channel both in station mode and WiFi direct so that the radio performance is optimized.
    • When working as an access point, DFS capable channels in band A are not currently supported.
    • The QCA6564 wireless chip does not support Wake On Wireless LAN.

ConnectCore 6 Plus

  • ConnectCore 6 Plus System-on-Module (SOM)
    • NXP i.MX6QP 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 SBC
    • The Micrel PHY KSZ9031 may take between five and six seconds to auto-negotiate with Gigabit switches.

ConnectCore 6

  • ConnectCore 6 System-on-Module (SOM)
    • 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).
    • When using softAP mode on Band A on the Qualcomm AR6233, channels used for Dynamic Frequency Selection (DFS) are not supported.
    • The Qualcomm AR6233 firmware does not support the following configuration modes:
      • Concurrent modes involving P2P mode, such as P2P + softAP or P2P + STA.
      • Bluetooth + softAP + STA concurrent mode.
    • A maximum of five clients are supported when using Qualcomm's AR6233 in softAP mode.
    • A maximum of ten connected devices are supported when using Qualcomm's AR6233 Bluetooth Low Energy mode.
  • ConnectCore 6 SBC
    • The Micrel PHY KSZ9031 may take between five and six seconds to auto-negotiate with Gigabit switches.

Support Contact Information

For support questions please contact Digi Technical Support:

When you contact Digi Technical Support, include important system details and device information to help Digi resolve the issue more quickly.

  1. In the device, run the command 'sysinfo'. This generates the following file: /tmp/<current timestamp>.txt.gz.
  2. Attach the <current timestamp>.txt.gz file to your support ticket.
You can’t perform that action at this time.
