STM32F746-DISCO CU2 & CU4 Display Models

[BA2]

Hello,

I am Bansi Attara. I initially used the STM32F7508-DK for my application, but due to its obsolescence, I transitioned to the STM32F746G-DISCO. During this shift, I encountered two variants of the STM32F746-DISCO:

1. DK32F746G$CU4
2. DK32F746G$CU2

While the second model (DK32F746G$CU2) works perfectly, the first model (DK32F746G$CU4) has issues with proper display functionality.

I have attached an image for your reference to help illustrate the issue.

Thank you for your attention to this matter.

Best regards,
Bansi Attara
