Firmware that runs on SDM. Implements many functions including the functions listed here:
• FPGA configuration
• Voltage regulator configuration
• Temperature measurement
• HPS software load
• HPS Reset
• RSU
• Read, erase, and program flash memory
• Device security, including authentication and encryption
Firmware to identify and load the highest priority image. Previous versions of this user guide refer to decision firmware
as static firmware. Starting in version 19.1 of the Intel Quartus Prime software, you can use RSU to update this
firmware.
Decision firmware data structure containing the following information:
• The Direct to Factory Image pin assignment.
•
PLL settings for the external clock source. This optional clock source drives
to OSC_CLK_1 Clock Input.
• Quad SPI pins.
A list of application image addresses in order of priority. When you add an image, that image becomes the highest
priority.
Data structure to facilitate the management of the flash storage.
Configuration bitstream that implements your design. This image includes the SDM firmware.
The fallback configuration bitstream that the RSU loads when all attempts to load an application image fail.
Contains the factory image, the application images, the decision firmware, and the associated RSU data structures.
An image that updates the following RSU-releated items in flash:
• The factory image
• The decision firmware
• The decision firmware data
