SiP SVC sample
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.
