3.2.4. HPS Boot First Dual Flash System

In a dual flash system, the SDM flash such as an active serial flash stores the configuration bitstream. The HPS flash such as an SD card stores the HPS SSBL and the rest of the OS files.

All the HPS flash devices are supported:
  • SD Card
  • eMMC
  • NAND

Depending on the boot stage that performs the FPGA configuration, you have the following options for storing the FPGA core and I/O configuration file:

  • In the HPS flash partition—The SSBL initiates configuration.
  • In the OS file system—The OS initiates configuration
