Hi, I was wondering where is the content of the SPIFlash how to to compile it. Thanks

Hi @pineappletikka thanks for your interest in this, I have not even built this board. The external memory is for storing configurations in order for the FT2232H to be set to operate in different modes, as far as I know. As to how to write to it, I haven't looked into it. I will update these details when I make this board.

In case you need more information, check the [datasheet](datasheet https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT2232H.pdf) page 46.

The FT_Prog utility is used to write to the external memory

Hi @Muriukidavid, thanks for the prompt reply! I will definitely have a look at those documentations. Good luck with the manufacturing and keep us up to date! :)
