Figure 3. External Configuration Host with HPS Flash

An external configuration host with HPS flash provides an SDM configuration bitstream containing:

  • SDM configuration firmware
  • FPGA I/O and HPS EMIF I/O configuration data
  • FPGA core configuration data
  • HPS FSBL code and HPS FSBL hardware handoff binary

In this system layout, you can use the HPS flash to store the HPS SSBL, Linux* image device tree information and OS file system. This layout enables the device to boot into an OS such as Linux*.
