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

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.
