configuration data starting from address 0 of the serial flash device.
3.2.7.1. Understanding Quad SPI Flash Byte-Addressing
At power-on the SDM operates from bootROM. The SDM loads configuration firmware from Quad SPI flash using 3-byte
addressing. Once loaded, the SDM configures the Quad SPI flash to operate in 4-byte addressing mode and continues to load
the rest of the bitstream until configuration completes.
Intel Agilex devices support the following third-party flash devices operating at 1.8 V:
• Macronix MX66U 512 MB, 1 and 2 gigabytes (GB)
• Macronix MX25U 128 megabyte (MB), 256 MB, and 512 MB
• Micron MT25QU 128 MB, 256 MB, 512 MB, 1 GB, and 2 GB
Micron and Macronix both offer Quad SPI memories a density range of 128MB—2GB.
