How to write to and read from fpga flash memory?

I'm trying to store data inside the flash memory which I can read from later. For example, I want to store data such as 0001,0010,0011,0100. However, most resources found is to load the configuration...

Are you talking about a separate configuration flash memory? Cyclone V does not have onboard flash.

Configuration flash is for just that, configuring the FPGA device. I suppose if you allocated part of it to be writable by the FPGA and then configured the FPGA with a flash controller IP, you could do it, but maybe it would be better to understand what your goal is here.

    attached is the block diagram of the FPGA I'm using. The goal is to access the 512MB flash to store multiple data which later can be read from and arithmetic operation can be performed on the data. The result will the be stored inside the flash again. Do you have information on how to store data inside the flash?
