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.

@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.

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

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.
