Black display after flashing any demo project in F769

[BHure.1]

After my lost battle with H750 and H745, I wanted to have a small win. However, it doesn't work like that. I took my F769 disco board and flashed the most basic sample project in touchgfx - directly from touchgfx, no modification on the interface/code. The display went black and did not want to work even I reset/unplugged the board.

Tried with the sample demo for F769 from ST site- black display also -- both tried to flash from ST utility and CubeProgrammer( I have 2.6.alpha cube programmer).

I then tried the Embedded wizard demo for F769 and to my surprise, running their flashing master demo works.

I have TouchGFX 4.15.0 & Cube Programmer 2.6 alpha.

What am i doing wrong?

Hello,

Please provide the steps.

I have tried with my F769 disco and everything works perfectly.

• Open Designer 4.15
• Select F769-Disco Application Template
• Select any UI Template (animated image example for instance)
• Generate code
• Run Target (works)

The only thing different that I see different so far is that I use CubeProgrammer 2.5 but I don't think that would be the issue.

Maybe could you give the version of your board ? Mine is MB1225B. And the display is MB1166 Rev A.
