TrustFence support in Digi Embedded Yocto is encapsulated in the TrustFence class.
This class must be inherited into your project’s conf/local.conf
configuration file to use TrustFence support:
conf/local.conf
INHERIT += "trustfence"
The TrustFence class configures a set of default configuration options, including:
-
Secure boot with signed images
-
U-Boot environment encryption
Trustfence features are only fully supported on closed devices. See Secure boot overview. |
