stm32h747-disco BSP problems

[Kfell.1]

Hello;

I have the STM32H747I-DISCO card CPN: STM32H747I-DISCO, FG: DK32H747/SAT1, and on the MB1166-A03 screen A225300631. The problem is when I try to test the card with the BSP example, I encounter the following problem:

I saw in the forums regarding this topic that an ST Employee suggests that the fix is available on GitHub:

https://github.com/STMicroelectronics/STM32CubeH7/commit/1c84713102f8509deb79ae14db8dbb104c17c45e#diff-8a5b12f7040dfb560c495dc0a1213725ba939bf19d531dd1e97067b6a1a79ec0

I tried replacing the files, but nothing is working, so please, I need an immediate solution.

best regards

Hello @Kfell.1 

Are you using the last version of the stm32cubeh7 firmware, CubeMX and CubeIDE.

If not please update them and retry.

Best regards.

Thank you for your response, yes, I am using CubeIDE 1.13.

For the firmware, is it also updated?

Else, take a look to those 3 psotes they may help you:

I have done all the updates; the problem is with the board's screen display

What is exactly the problem. Can you give more details.

Best regards.

The problem is that the examples from CubeIDE related to LCD do not work on the board. and the error is

I suggest you to use this updated drive and do the modifications mentioned in the best answer of this post. No need to use the link.

@Kfell.1 Could you tell us again, which example project are you using?

The file Utilities/lcd/stm32_lcd.c is used by several examples for that board, but there isn't one named "BSP" there.

Hi

I used BSP project in cubeide examples

Hello,

1-  Was stm32_lcd.c already included in the project?:

2- Check the availability of stm32_lcd.c under the path \Utilities\lcd\stm32_lcd.c

@Pavel A. The project is under the path: Projects\STM32H747I-DISCO\Examples\BSP

The project is not available on github (strange) but in the STM32CubeH7 zip package.

@Kfell.1: 

Sorry, at the beginning you posted a symptom of linking issue now you said that you are running the example with an issue in the LCD display.. I'm a bit confused! 

I've just run the example and it worked fine from my side:

But there is another thread which I think it describes the same symptom as yours: https://community.st.com/t5/stm32-mcus-touch-gfx-and-gui/stm32f769i-disco-really-noisy-tft-lcd-display/td-p/55127

I find the problem

the problem is the version of driver : the LCD FGRIDA FRD397B25009D-CTK replaced by  FGRIDA FRD400B25025A-CTK

thank you

FWIW... Got explanation why the BSP project does not exist in the Cube firmware package on github. It has been deliberately removed, along with few others - because of dependency on encumbered components that require license clickery, which disturbs automated CI. In the case of BSP that is probably the LCD display functionality.
