When enabled, this option instructs the Zephyr build process to
|
||
|
|
additionaly generate a TF-M image for the Secure Execution
|
||
|
|
environment, along with the Zephyr image. The Zephyr image
|
||
|
|
itself is to be executed in the Non-Secure Processing Environment.
|
||
|
|
The required dependency on TRUSTED_EXECUTION_NONSECURE
|
||
|
|
ensures that the Zephyr image is built as a Non-Secure image. Both
|
||
|
|
TF-M and Zephyr images, as well as the veneer object file that links
|
||
|
|
them, are generated during the normal Zephyr build process.

Note:
|
||
|
|
Building with the "_nonsecure" BOARD variant (e.g.

|
|
"mps2_an521_nonsecure") ensures that
