    • MCA: Reset, Watchdog, RTC, GPIOs and ADCs
  • Updated U-Boot to version 2017.03-r2
  • Fixed XBee RESET_N polarity assertion. Requires updating polarity of the digi,reset-gpio property of node xbee on device tree files derived from ConnectCore 6UL SBC Pro to use polarity GPIO_ACTIVE_LOW
  • Updated AWS Greengrass core to version 1.7.0
  • Updated kernel version to v4.9.135 for i.MX6 and i.MX6UL platforms.

2.4-r1

  • Release based on Yocto 2.4 (Rocko) including:
    • New toolchain based on GCC-7.2.0 and GLIBC-2.26
    • Updated Qt 5.9.4
    • Package upgrades and security fixes
  • Updated kernel version to v4.9 for ConnectCore 6 platform
  • Updated U-Boot to version 2015.04-r12
  • Updated Cryptoauthlib version to v3.0
  • Added support for Goodix 10" display
  • Updated documentation

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.

  • If TrustFence (TM) image encryption support is enabled, the uSD image will boot a signed U-Boot only.
  • 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 and ConnectCore 6 Plus) running a 4.9 kernel version fail to join to autonomous groups.
  • Trustfence secure console is not supported on U-Boot v2017.03. In order to use this functionality, U-Boot v2015.04 will be required.

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

  • 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.

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 8X

  • i.MX8QXP Processor
    • The following processor features are not supported in this BSP release: Power Management, PWM, ADC, RS485. They will be implemented in future releases.
    • 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.
  • ConnectCore 8X SBC Pro
    • USB 3.0 not supported.
  • Digi Embedded Yocto
    • The following features are not supported in this release for the ConnectCore 8X plaform:
      • Trustfence (TM)
      • Digi Remote Manager
