Intel Agilex User Manual

Both the factory image and the application images start with firmware. First, the decision firmware loads the firmware. Then,
that firmware loads the rest of the image. These implementation details are not shown in the figure above. For more
information, refer to the Application Image Layout section.
4.4.1.3. RSU Flash Layout – Your Perspective
The sub-partition table (SPT) manages the quad SPI flash. In devices that include the HPS, the HPS can access and read the
SPT and report it to the SDM. .
The Intel Quartus Prime Programming File Generator creates the SPT when creating the initial manufacturing image. To
ensure reliable operation, the Programming File Generator creates two copies, sub-partition table and the configuration
pointer block, SPT0 and SPT1 and CPB0 and CPB1
The initial RSU image stored in flash typically contains the following partitions:
