enabled There is currently no support on fw_printenv/fw_setenv to access an encrypted environment. This commit removes the package if U-Boot environment encryption is enabled to avoid environment corruption on access. It also documents the issue as a known issue. https://jira.digi.com/browse/DEL-2625 Signed-off-by: Alex Gonzalez <alex.gonzalez@digi.com> |

Known Issues and Limitations
- When using the TrustFence (TM) U-Boot environment encryption, access to the U-Boot environment from the Linux OS is not supported.
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
