2.2.1. External Configuration Host Only
In this example, the external configuration host ( Avalon® streaming or JTAG) provides the SDM with a configuration bitstream that consist of:
- 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
Because the HPS SSBL (or subsequent OS) is not part of the bitstream, the HPS can only boot up to the FSBL stage. This setup is applicable if you are using the FSBL to run simple applications (for example, Bare Metal applications).
You can use the FSBL to retrieve the SSBL from other sources, such as through the HPS Ethernet MAC interface. To implement these modes of access, you must create a working Ethernet software stack in the FSBL.
