Why does reading or writing across the FPGA-to-HPS Bridge in Agilex™ 5 devices fail?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    In Agilex™ 5 devices, the FPGA-to-HPS Bridge (F2H) hardware currently supports AXI5, ACE-lite, and AXI4. However, some signals are not tied-off appropriately, which results in unsuccessful transactions.

    Resolution

    To work around this problem, use Quartus® Prime Pro Edition software version 24.1 and install the patches below which will configure the appropriate AXI signals to allow successful transactions across the F2H bridge.
