Compile problems from STM32CubeIDE in STM32H747-DISCO based TouchGFX project

[Pensees]

Hello,

I have compile problems with STM32CubeIDE.

< Detail information >

1) STM32CubeIDE version : 1.7.0

2) TouchGFX version : 4.17.0

3) Target Board : STM32H747I-DISCO

4) Process order in my case

• Create new STM32 project (select STM32H747I-DISCO board, targeted language is C++)
• Configure Software Packs (in .ioc file)

• GUI design from TouchGFX program (open ApplicationTemplate.touchgfx.part)
• Generate code
• Refresh ​STM32 project and copy necessary files From TouchGFX project to STM32 project
• Build project (in my case, compile error occurs)
• If needed, added Paths

5) Compile error messages 

Attached my project.

Please advise for me, thanks.

It seems to me you could figure this out by following page 2 of the attachment. Meanwhile, I would suggest you to disable binary generation as shown in page 3 so you do not need to spend much time waiting for big binary (>2GB) generation.

Thanks to Ethan HUANG, it compiles successfully.

And upload CM4.elf file also done.

But, CM7.elf file upload failed.

First (and only) guess is "external loader" is not enabled in "Debugger". Please take a look at the attached picture below:

It possible to load hex file via "STM32 ST-Link Utility" but nothing displayed...

[Ethan HUANG]

It's not clear to me "nothing display". I think you got either one below:

1. black screen
2. white screen

If you got #1, you need to figure out display setting first. If you got #2, it's normal because your TouchGFX project is pure white.

Anyway, I would highly recommend you start the project by using TouchGFX Designer w/ TouchGFX Board Setups of H747I-DISCO so you can get rid of much of the hardware configurations and therefore can focus on GUI design.

Starting from CubeIDE is a bit challenging and I would suggest you to refer to section "How-to" from the link below":

https://support.touchgfx.com/docs/development/board-bring-up/how-to/01-create-project

As you can see from section "3. Framebuffer in internal RAM

" , you may need to check if you can really see a read screen before enabling TouchGFX.

Upload is done in STM32CubeIDE. But still nothing displayed.
