[Trusted-services] Re: Does trusted service framework project support the trusted service run in S-EL1?

Hi Carlos,

thanks for the clarification 😊.

I double checked with the document owners and according to them the supplement does not require the service to run at S-EL1, only the example message sequences describe such a scenario. Hopefully, the next public release will remove this ambiguity.

May I ask if the target you are working on is an IoT or a mobile platform?

Hi George

1. Hafnium, running on S-EL2 2. https://developer.arm.com/documentation/den0138/latest, according to this document, this SP should run on S-EL1 3. TPM trusted service FFA over CRB 4. Sorry, it my typo, it should be entry.S
