Arm SiP Services on Intel Agilex SoC FPGA

Overview

This sample demonstrates the usage of SiP SVC subsystem.This sample performs a voltage value query from Secure Device Manager in Intel Agilex SoC FPGA.

Caveats

SiP SVC subsystem relies on the firmware running in EL3 layer to be in compatible with protocol defined inside the SiP SVC subsystem used by the project.
The sample application relies on the Trusted Firmware ARM firmware in intel Agilex SoC FPGA query the voltage levels in Secure Device Manager.

Building and Running

For building the application:

# From the root of the zephyr repository
west build -b intel_socfpga_agilex_socdk samples/subsys/sip_svc

For running the application the Zephyr image can be loaded in DDR memory at address 0x00100000 and ATF BL31 at 0x00001000 from SD Card or QSPI Flash in ATF BL2.
