Once the Intel Stratix 10 SoC FPGA exits POR, the SDM samples the MSEL[2:0] pins1 to determine the boot source. Next, the device configures the SDM I/Os according to the selected boot source interface and the SDM retrieves the configuration bitstream through the interface. SDM can boot from the following boot sources listed in the following table.
SDM Boot Source | Details |
---|---|
Avalon-ST (x8/x16/x32) | Supported |
JTAG | Supported |
Active Serial (AS)/ Quad SPI | Supported. SDM only boots in x4 mode for active serial flash and Micron* MT25Q flash. Other supported quad SPI flash devices boot in x1 mode. After the configuration firmware loads into the SDM, the SDM can switch the flash into x4 mode. |
The typical configuration bitstream for FPGA configuration first contains:
- Configuration firmware for the SDM
- FPGA I/O and HPS external memory interface (EMIF) I/O configuration data
- FPGA core configuration data
- HPS FSBL code and FSBL hardware handoff binary data
The SDM completes the configuration of the FPGA core and I/O, and then copies the HPS FSBL code and HPS FSBL hardware handoff binary to the HPS on-chip RAM.
