1.2. Intel® Stratix® 10 SoC FPGA Boot Overview
The Intel® Stratix® 10 SoC FPGA combines an FPGA with a hard processor system (HPS) that is capable of booting Bare Metal applications or operating systems such as Linux*.
When booting the device from a power-on reset, you can choose between two different methods of booting:
- FPGA Configuration First Mode—When you select the FPGA First option, the SDM fully configures the FPGA, then configures the HPS SDRAM pins, loads the HPS first-stage bootloader (FSBL) and takes the HPS out of reset.
Note: The FPGA and all of the I/Os are fully configured before the HPS is released from reset. Thus, when the HPS boots, the FPGA is in user mode and is ready to interact with the HPS. Optionally, the SDM can hold the HPS in reset until instructed by the user. To release the HPS from reset, you can use soft IP such as a mailbox client to send a mailbox request to the SDM.
- HPS Boot First Mode—When you select the HPS First option, the SDM first configures the HPS SDRAM pins, loads the HPS FSBL and takes the HPS out of reset. Then the HPS configures the FPGA I/O and FPGA fabric at a later time.
Note: This mode is also referred to as Early I/O Release Mode or Early I/O Configuration. After power-on, the device configures a minimal amount of I/O required by the HPS before releasing the HPS from reset. This mode allows the HPS to boot quickly without having to wait for the full configuration to complete. Subsequently, the HPS may trigger an FPGA configuration request during the SSBL or OS stage.
