4.5.2. HPS Boots First

In order to obtain the SOF file to be used to configure the device through JTAG with the HPS Boots First option, you need to generate a bitstream intended for another configuration method, such as AVST. An SOF file called design_hps_auto.sof is expected to be created automatically, and it can be used to configure the device. You discard or ignore the Phase 1 AVST bitstream, and use the Phase 2 bitstream to later configure the FPGA fabric from HPS software.

The following figure shows an overview of the process:
Figure 13. Configuration over JTAG with HPS Boots First
The following steps are involved:
  1. Compile hardware project with Intel® Quartus® Prime to obtain the SOF file.
  2. Compile the HPS FSBL source code to obtain the HPS FSBL hex file, or use a precompiled one.
  3. Use Programming File Generator to create the following files:
    • Raw Binary File (RBF): contains the small phase 1 configuration bitstream. Discard this file.
    • hps_auto SOF File: contains the phase 1 configuration data, and the HPS FSBL.
    • Core RBF File: contains the typically much larger phase 2 configuration bitstream. To be used by HPS software later to configure the fabric.
  4. Use Intel® Quartus® Prime Programmer to configure the device using the phase 1 hps_auto SOF file. HPS software starts running, beginning with HPS FSBL.
  5. At a later time, HPS software configures the FPGA fabric by using the phase 2 Core RBF bitstream.
The following example creates the files for HPS boot first:
quartus_pfg -c design.sof design.rbf -o hps_path=fsbl.hex -o hps=on
The input and output files for this command are:
  • Input Files:
    • design.sof
    • fsbl.hex
  • Output Files:
    • design.hps.rbf—to be discarded
    • design_hps.auto.sof—Phase 1 SOF
    • design.core.rbf—Phase 2 Core RBF
