Hi Andrej,

For the SVC issue - that should be easy to resolve: The only point at which the NS application stored in the repo uses SVC is when TFM_NS_CLIENT_IDENTIFICATION is enabled.

If your scope is a feasibility study with any OS you can turn off this feature by adding set (TFM_NS_CLIENT_IDENTIFICATION OFF) to your Config*.cmake build configuration or toggle the corresponding line in CommonConfig.cmake to OFF to turn it off globally for all build configs in your repo.

Regards Miklos

Hello,

Do you know about any existing port of FreeRTOS (instead of RTX) to TFM? Did somebody a feasibility study? I have just started to look at it, and immediately detected a conflict, both are using Supervisor Calls (SVC) for own needs.

Thanks, Andrej
