stm32F469i-DISCO strange behavior with LCD

[DKash.1]

Hi to all,

I'm new in stm32 and I have stm32F469i-DISCO board.

Factory demo worked well on it.

Then I've started to exploring examples from STM32CubeIDE (New -> STM32 project -> Examples -> filtered by board)

Last couple of tries was LCD_DSI_CmdMode_DoubleBuffering, LCD_Paint, TouchGFX

Just create new project - build and Run

And here example what I can see on the LCD

Then I'm taking compiled demo binaries from official page and program it using STM32CubeProgrammer

If I leave board without power for some time, 10 - 15 mins, this white lines gone and image became good. But this not work with examples - they didn't work after board "rest".

Also tried to program binaries compiled by STM32CubeIDE with STM32CubeProgrammer - the same but with some verification errors.

And official demo binaries also says verification errors.

Is it some hardware issue on my board and I need new one?

Any ideas?

Your board equip too external QSPI memory and you need manage it.

Error on image is about it.

Hello.

Change project settings: [c/c++]>[patch and symbols]>[symbols]

delete USE_STM32469I_DISCO_REVC

add USE_STM32469I_DISCO_REVA

[DMusz.2]

like this 🙂

[DMusz.2]

Depending on the version of the board:

USE_STM32469I_DISCO_REVA (25Mhz external osc)

USE_STM32469I_DISCO_REVB (8Mhz external osc)

USE_STM32469I_DISCO_REVC (NT35510 lcd driver)

There also look to be a couple of External Loaders
