# 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).
|
|
* Cellular modem Telit LE910-EUG
|
|
* Firmware version 17.01.522 not supported. Digi Embedded Yocto 2.2 has been tested
|
|
with FW version 17.00.523.
|
|
|
|
## Digi ConnectCore 6UL
|
|
|
|
* 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
|
|
|
|
## Digi ConnectCore 6
|
|
|
|
* 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
|
|
|
|
## Digi ConnectCore 6 SBC
|
|
|
|
* The Micrel PHY KSZ9031 may take between five and six seconds to
|
|
auto-negotiate with Gigabit switches
