Hi Sarra,
Thanks for the info, so are we thinking these are not faulty boards but rather some issue with the HAL?
Thanks
Andy

Hi Sarra,
I wanted to know if it is feasible to fix the screen problem. I bought the board to do a project for the university which has a deadline. It is to know if I have to return them due to lack of time. Could you please tell us how the issue is?
Thanks!

I met same question as you. TouchGFX works good, while AI-Vison shows noise picure

Hi @Az.2
It is a problem with the ST BSP code with these new boards. There is nothing you can do about it till ST fix the software.
This fix has been in progress for 3 weeks or so.
If you really need to use this board then maybe look for an old one somewhere or just wait till they fix it.

Thanks a lot!
It seems hard to buy a old one since I cannot find someone or somewhere sells it.

I'm not sure. It makes sense that it works. I wanted to try sending the image via USB so I don't have to use the LCD, but I never did it because I thought the problem with the LCD would be fixed soon.
It would be to combine the example of AI with that of the webcam. If I have time I'll give it a try and let you know if it works.
If you try it and it works for you, I would appreciate it if you could confirm it!

Hey Guys, GOOD NEWS!
It's the screen hardware problem, I bought a separate screen (B-LCD40-DSI1 4" WVGA TFT LCD) from mouser, which is same type but can normally display.
