Hi Vkap,


Apologize that it cannot be. You can only use 1 QSPI flash and a QSPI flash IP. I would suggest you to choose bigger QSPI flash, then, include a serial flash IP in your design. You may refer to link below for more information about the serial flash IP

With the IP, you can interact with the flash memory during user mode. However, you may want to avoid the memory addresses which you bitstream is stored in.


Thank You.
