Description
Referring to the Intel Agilex® 7 FPGA I-Series Development Kit schematic diagram on page 2, you will see that the EPCQ Flash device is connected directly to the Intel Agilex 7 FPGA. However, when you check on the development kit, the EPCQ flash device is actualy connected to Intel® MAX® 10 FPGA. This can be verified by referring to the same document on page 35.
Resolution
The EPCQ device is actually connected to the Intel® MAX® 10 FPGA. You can verify this by referring to page 35 of the same document. The block diagram will be fixed in a future release of this document.
