Hardfault on STM32F769 using TouchGFX

pascalous · ‎2024-09-09

hi

I use touchgfx 4.24 , STM32CubeIDE 1.16 and STM32cubeMX 6.12

I do a project with touchgfx, I import it on cubeide, no problems to launch it on the card (STM32F769I-DISCO)

I make a modification ( uart 5) on the file ioc and the bilioteque (newlib rentrand) as requested by CubeMX. When I launch after compilation I have an error, of type MemManage_Handler
I do not see mistake that I could have comeate.
Who can help me?

thank

Hello @pascalous ,

I would guess it is an issue with FreeRTOS actually.

Can you try to activate your UART5, but when do not fix the warning about NEWLIB_REENTRANT, when STM32CubeMX asks you "Do you still want to generate code", just click "Yes".

Regards,

Gaetan Godart
Software engineer at ST (TouchGFX)

Hello @pascalous and welcome to the community,

Check the MPU config and if you declared something in a memory region that MPU prevents that access.

I just remade a project, I neither is put any personal code. I put uart5 in assynchrone mode, I complicate the file ioc and I have the same problem. uart5 and mpu have they the same memory zone?

Before enabling the UART, did you get the same behavior?

Sorry your project doesn't compile it's incomplete. You need to attach the complete project. Also I don't see any TouchGFX code in your project.
