6. Configuring the FPGA Fabric from HPS Software

Configuring the FPGA fabric from HPS software is supported only when using the HPS Boot First mode.

When creating the configuration files, you obtain a phase 1 HPS configuration file, and a phase 2 FPGA fabric configuration file. Typically, the two files come from running the Quartus® Prime Programming File Generator on a SOF file resulted from compiling a hardware project.

The phase 1 and phase 2 configuration files can also be obtained from different projects, or modified projects, if the following conditions are met:
  • The same Programming File Generator version is used for generating both files, as this ensures both have the same SDM firmware version.
  • Both SOF files that are used have the same HPS IO settings and HPS DDR settings.
  • The FPGA fabric can be configured from both U-Boot and Linux.
Note: For more information about project compatibility between phase 1 and phase 2 designs, refer to Hardware Project Compatibility in HPS Boot First Mode.
