    Hi jmoha4,

    You can use Examine option in Quartus programmer to read back the flash data.

    Open Programmer --> Add Device

    Choose your FPGA device and click Okay. (For my case I use cyclone 10 LP 10CL08Y)

    Right Click on your device --> choose "Attach Flash Device"

    Choose your Flash device and click Okay. (For my case I use EPCQ64)

    Finally, Tick Examine and click Start

    I hope this will help.

    Cheers
