Sometimes, it may be desired that the DEY project does not sign the artifacts, for example, if they are going to be externally signed on a secure server. In this case, the user sets TRUSTFENCE_SIGN="0". On STM platforms, all the variables were being set if TRUSTFENCE_SIGN="1" and authentication support is not enabled on TF_A otherwise. Set TF_A_SIGN_ENABLE (which adds authentication support to TF_A) always for STM platforms (as long as the project inherits the trustfence class) and set FIP_SIGN_ENABLE="0" if its sibling TRUSTFENCE_SIGN="0", so that DEY doesn't sign the FIP image either.

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.
- 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).
- Wireless
- Performance of the wireless interface is reduced when using concurrent mode, as the wireless interface is shared between several different functionalities.
- When using wireless concurrent mode, Digi recommends you keep the different modes on the same frequency channels. For example, when configuring access point mode on channel 36 in the 5GHz band, connect to the same channel both in station mode and Wi-Fi direct so that the radio performance is optimized.
- When working as an access point, DFS-capable channels in the 5GHz band are not supported.
- For P2P connections Digi recommends "Negotiated GO" modes. The QCA6564 devices (ConnectCore 6UL, ConnectCore 6 Plus, and ConnectCore 8M Nano) fail to join autonomous groups.
ConnectCore MP15/MP13
- ConnectCore MP1 System-on-Module (SOM)
-
Wireless
- P2P on the ConnectCore MP1 doesn't currently work in concurrency with other modes (station or SoftAP).
-
The following features are not yet supported:
- TrustFence
-
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.
- The QCA6564 wireless chip does not support Wake On Wireless LAN.
