220.127.116.11. Specifying Boot Order for Intel® Agilex™ SoC Devices
For Intel® Agilex™ SoC devices you can specify the configuration order, choosing either the FPGA First or the Hard Processor System (HPS) First options.
When you select the FPGA First option, the SDM fully configures the FPGA, then configures the HPS SDRAM pins, loads the HPS first stage boot loader (FSBL) and takes the HPS out of reset. In this mode the fabric begins functioning just before the HPS exits reset. Note that FPGA First option does not allow FPGA reconfiguration by using HPS. This user guide defines a state when the FPGA is functional. Configuration and initialization are complete.
- Minimizes the amount of SDM flash memory required.
- Minimizes the amount of time it takes for the HPS software to be up and running.
- Supports FPGA reconfiguration while the HPS is running.
