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

Description

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

Resolution

To work around this problem, use the 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.
