Using FT4222H, how should I handle this prompt now?

[hackpascal]

Open https://packages.msys2.org/package/mingw-w64-x86_64-json-c?repo=mingw64,
then click the link of the "File" row (e.g. https://mirror.msys2.org/mingw/mingw64/mingw-w64-x86_64-json-c-0.17-1-any.pkg.tar.zst) to download the package.
Unpack the package, and copy mingw64/bin/libjson-c-5.dll to ufprog directory.

After copying, run the command again to prompt these

Where did you download the ufprog? The released zip file contains all necessary files.

[zj53523094]

I downloaded it from the place where you replied on the oshwhub.com source platform, but I don't know how to compile it myself. That may be due to incomplete package compilation. Can the boss conveniently provide a compiled package?

[hackpascal]

for the rest dll files you can download from https://github.com/hackpascal/ufprog/releases/tag/v1.0-2023-09-18

currently ufprog is under development and cannot build release package now

This connection works well. Now I just don't know how to add an adapter chip? Has W25Q64 already been adapted? How did you connect the wiring during your testing? I am thinking, as shown in the picture, the most likely reason why the chip does not recognize it is due to a connection issue, right? Could you please give me some guidance on the wiring?

I've tested almost all flash chips which can be purchased online.
Comparing to CH347/FT2232, The communication of FT4222H is not very stable.

[zj53523094]

Thank you very much. I just wanted to say that it would be convenient to share the circuit schematic during your testing. The chip was not recognized, and I am even more worried about my wiring being connected incorrectly.I will follow your principle and investigate my own issues again

[zj53523094]

Some important principles cannot be seen, can you share a complete one?

[zj53523094]

Which pin are you using for the chip selection signal?

[zj53523094]

Which PIN is WC # 、 CS connected to the main chip?

[hackpascal]

I am an amateur at PCB layout... If you really want the full design, just leave me an email address.

@.***。thinks

nothing but asterisks can be seen. lol

Which PIN is WC # 、 CS connected to the main chip?

WC# is tied to GND with 10k resistor
