HardFault in TouchGFX Default Project on STM32H7S78-DK

[diogomargalho]

Hello,

I am using a STM32H7S78-DK and I created a project using TouchGFX Designer with the default empty template. However, when I try to run it, the board immediately hard faults.

Stack Trace:

main()
└── MX_TouchGFX_Init()
└── touchgfx_components_init()
└── nema_init()
└── nema_sys_init()
└── tsi_malloc_init_pool_aligned(1, (void*)nemagfx_stencil_buffer_mem, (uintptr_t)nemagfx_stencil_buffer_mem, NEMAGFX_STENCIL_POOL_SIZE, 1, 8);

I've seen some some discussions where the CRC could be the problem, everything seems fine with the CRC, and i don't think any of the issues are directly related to the NeoChrom GPU.
A while back i tried the same project setup, and it was fine. After that i was checking Rust with Embassy and adding lvgl to an empty project. I'm not sure if it could be related, it might just be a weird coincidence.

Hello @diogomargalho ,

Can you describe the steps to achieve this error?

I open TouchGFX Designer 4.25.0, create a new project with STM32H7S78-DK with freeRTOS and RGB565 and I am able to flash from the TouchGFX Designer itself.

Regards,

The steps to achieve it are:

1. Open TouchGFX Designer.
2. Create 'STM32H7S78 Discovery Kit'
3. Generate Code
4. Open the project with STM32CubeIDE
5. Add the Boot ELF to the Application Startup
   
6. Debug 'STM32H7S78-DK_Appli'

After this it crashes.

I never flashed a STM32H7S78-DK through STM32CubeIDE.

Usually, I build the code through STM32CubeIDE and then I open STM32CubeProgrammer to flash.
I select the external loader for the STM32H7S78-dk board then I connect the board, then I flash the boot and then I flash the appli.

Would this be ok for you to do that or do you really want to flash through STM32CubeIDE (I am not an expert on STM32CubeIDE but I could ask someone).

I don’t think the issue is with flashing. I’ve flashed from STM32CubeIDE in other projects without any problems. I think the problem could be in the code or the board itself, but I can try flashing through STM32CubeProgrammer.
