Part 2.6: QSPI Flash

The FPGA core board AC7200 is equipped with one 128MBit QSPI
FLASH, and the model is 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, core application
code and other user data files. The specific models and related parameters of
QSPI FLASH are shown .
Position
U8
QSPI FLASH is connected to the dedicated pins of BANK0 and BANK14 of
the FPGA chip. The clock pin is connected to CCLK0 of BANK0, and other data
and chip select signals are connected to D00~D03 and FCS pins of BANK14
respectively. Shows the hardware connection of QSPI Flash.
