# 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.
|
||
|
||
* When using TrustFence (TM) encrypted images secure boot support, the CAAM
|
||
will hang the processor when trying to authenticate an encrypted firmware image
|
||
after a failed attempt. Hence the target needs to be reset after an
|
||
authentication failure.
|
||
* If TrustFence (TM) image encryption support is enabled, the uSD image will
|
||
boot a signed U-Boot only.
|
||
|
||
## Digi ConnectCore 6UL
|
||
|
||
* In the Bluetooth interface, the UART hardware flow control doesn’t work
|
||
properly. To work around this problem the UART is configured without hardware
|
||
flow control at 115200 bps, reducing the maximum throughput of this interface.
|
||
This problem will be corrected in newer revisions of the hardware.
|
||
|
||
* U-Boot version dub-2015.04-r4.5 may report running on Starter Board version 1
|
||
even when your Starter Board is version 2. In that case Ethernet does not work
|
||
in U-Boot. More recent versions of U-Boot fix this issue.
|
||
|
||
## 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
