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.
Position
U13,U14
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.
