Is there Security Extension support for ARMv7-A architecture for ThreadX?

Question

We are using Security Extension feature for ARMv7-A architecture. Is it possible for ThreadX and the user application to run in non-secure mode with support for calling secure services for ARMv7-A architecture? Such secure services may have low priority so that context switching is needed. Only ARMv8-M porting of ThreadX seems to support such feature.

Answer 1

ThreadX does not have any security extension support for ARMv7-A.
