Seem that something on my Discovery board is going wrong.. How to flash original demo on STM32F469I-DISCO? How to go successfull with examples on TouchGFX?

I bought a STM32F469-DISCO to start my adventure with STM's MCU.

Included demo is great.

Now I'm trying to upload some other example from CubeIDE and TouchGFX.

I've updated st-link, and go.. (I'm working on a windows 10 system)

From CumeIDE some examples for my Discovery board work fine. For example from CubeIDE -> new Project -> Example Selector -> StM32F469I-DISCO -> BSP and HID_RTOS are running fine.

From TouchGFX no example work on my board: Run Simulator go fine, Run Target get my board into black screen.

The strangest thing is that if I try to reload the original demo it don't work:

even if I flash the original HEX from https://www.touchgfx.com/resources/demos/

even if I run from CubeIDE -> new Project -> Example Selector -> STM32F469I-DISCO -> TouchGFX

The effect is like in the video attached: seem like something is going wrong on my device.

I suppose that the board is ok: It worked with original firmware, and it work with others examples from IDE.

But:

 - how to run examples from TouchGFX?

 - how to reflash original hex from touchgfx.com?

Thanks

Try using STM32 Cube Programmer, and appropriate external loader for the F469I-DISCO

And reload the demo that came with the device.

Hi @Community member​ , thanks a lot for your support.

Great, that hex file in 1.2 vorsion work fine! The 1.3 no: it work similar to the video I've uploaded before.

How have you found it? :clapping_hands:

So, now I've to find the most important thing: make work with TouchGFX

Video is not viable on my Win 7 system. You'd do better with something in-line, or on YouTube.

There might be different versions of the board/screen, no way to make a determination from here. Could be a backlight or initialization issue.

Those are some pic of what happen if I run te TouchGFX demo from CubeIDE

After any reset pressure on the rear of the board the sequence could change... It's really strange.

In the other side, if I "Run Target" any example from TouchGFX the screen is alwais black. When I push the reset button 2 leds blink, and I can see the backlight that fade on. But nothing appear on the LCD
