[DRA821]Sciserver some problem comfirmation

Hi Xie,

The Sciclient must continue to be initialized for communication to request for all RM, PM, and Security services.

Sciserver is a new module which enables MCU R5F to service requests for all non-secure entities on the SoC. DMSC only services requests by secure entities. It is only required if you have other cores (e.g. A72/Linux) which must request services which previously were intended for DMSC.

Here are a few links to help explain the new architecture, including which libraries are required and what modules must be included in the application:

Please let me know if you have any specific questions.

Hi Xie,

Yes, you are correct on both - sciserver is required for in order Main R5F to use any Sciclient API. The sciserver is only implemented for TIRTOS in the PDK example, but other OS will require porting.
