Issues with Writing to Flash Memory Using FTDI FT2232HQ

[GT_ahm]

To whom ever it may concern

I hope this message finds you well.

We are currently working on a project involving the Digilent Arty A7 evaluation board, which utilizes an FTDI FT2232HQ chip.
 Our objective is to program the flash memory (S25FL128SA) using the FT_PROG utility.
 While we have successfully erased the FTDI device, we are encountering difficulties when attempting to rewrite it.
Specifically, we aim to upload a program into the flash memory without relying on Vivado, as our goal is to provide our client with a solution 
that allows them to perform the programming through a small application.
Could you please provide guidance or a solution for successfully writing the bin file to the flash memory using the FTDI FT2232HQ? 

Also what to do to revert back my FTDI FT2232HQ chip to its orginal digilent configuration.

Thank you for your attention to this matter. I look forward to your response.

Best regards
