Part 4: QSPI Flash

The AX7350B FPGA development board is equipped with a 256MBit
Quad-SPI FLASH chip, model W25Q256FVEI, which uses the 3.3V CMOS
voltage standard. Due to the non-volatile nature of QSPI FLASH, it can be used
as a boot device for the system to store the boot image of the system. These
images mainly include FPGA bit files, ARM application code, and other user
data files. The specific models and related parameters of QSPI FLASH are
shown in Table 4-1.

QSPI FLASH is connected to the GPIO port of the BANK500 in the PS
section of the ZYNQ chip. In the system design, the GPIO port functions of
these PS ports need to be configured as the QSPI FLASH interface. Figure 4-1
shows the QSPI Flash in the schematic.
