Part 6：ZYNQ Processor System (PS) peripherals
ZYNQ is composed of the PS part of the ARM system and the PL part of
the FPGA logic. Some peripherals on the FPGA core board are connected to
the IO of the PS, and some peripherals are connected to the IO of the PL. First
introduce the peripherals connected to the PS part.

Part 6.1: QSPI Flash

The AC7010/AC7020 FPGA core board is equipped with a 256MBit
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
U6
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.
