Quad-SPI FLASH chip, model W25Q256, 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 6-1.

Position

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 6-1

shows the QSPI Flash in the schematic.
