1.2. System Components
The bitstream is stored in the configuration flash device (QSPI) connected to the SDM pins. The HPS software is typically stored in a mass storage flash device (SD/eMMC/NAND) connected to the HPS pins but can also be stored in the flash device connected to the SDM pins.
Component | Description |
---|---|
FPGA Configuration Data | When using FPGA first mode, this component of the bitstream contains the full FPGA and I/O configuration data. When using HPS first mode, it contains just the HPS and HPS EMIF I/Os. |
SDM Firmware | Firmware for the Secure Device Manager Provides commands for managing RSU. These commands are not directly accessible to you. Instead both U-Boot and Linux* offer services for accessing the functionality offered by the SDM commands indirectly. |
U-Boot SPL | The HPS First Stage Bootloader Initializes hardware and loads the HPS Second Stage Bootloader. |
ATF | Arm Trusted Firmware Provides secure services to U-Boot and Linux through SMC (Secure Monitor Call)5 |
U-Boot | HPS Second Stage Bootloader:
|
Linux* Drivers | Intel® RSU driver uses the functionality provided by U-Boot SMC and makes services available to applications running on Linux*. |
LIBRSU | Linux* user space library providing APIs for managing RSU. |
RSU Client | Linux* sample application which uses LIBRSU for managing RSU. |
Intel® provides an RSU solution that focuses on the reliable update of the components that are part of the configuration bitstream, and are located in SDM flash. It is your responsibility to devise a scheme for the reliable update of the rest of the system components.
