## Digi ConnectCore 6UL

## Digi ConnectCore 6UL Starter Kit

## 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
* When using TrustFence encrypted images secure boot support, the CAAM will
hang the processor when trying to authenticate an encrypted kernel image after
a failed attempt. Hence the target needs to be reset after an authentication
failure.
* NXP i.MX6 processor does not set the sticky bit which write protects the
SRK_REVOKE eFuse on closed devices. This means that in the ConnectCore 6,
key revocation is always possible, no matter the value of the Yocto macro
TRUSTFENCE_UNLOCK_KEY_REVOCATION.

## Digi ConnectCore 6 SBC

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