2.4.1.4. LWFPGA Slaves Address Space

The Lightweight (LW) FPGA Slaves address space is located in the FPGA core and accessed from the HPS through the LWHPS2FPGA Bridge. The LWFPGA Slaves address space in the FPGA core is of unlimited size (soft logic in the FPGA performs address decoding). A portion of the Peripheral region provides a window of 2MB into the LWFPGA Slaves address space. The base address of the LWFPGA Slaves window is mapped to address 0x0 in the LWFPGA Slaves address space.

The HPS is not able to boot from the LWFPGA Slaves address space.
