3.2.2. External Configuration Host with HPS Flash

Figure 8. External Configuration Host with HPS Flash
An external configuration host provides an SDM configuration bitstream containing the following components:
  • SDM configuration firmware
  • HPS EMIF I/O configuration data
  • HPS FSBL code and HPS FSBL hardware handoff binary

In this system layout, the HPS flash, contains the HPS SSBL, Linux* image device tree information, and the OS file system.

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
