Struggling with TouchGFX Generated Code Building on STM32Cube IDE.

[Karan 123]

Hi,

I am struggling Struggling with TouchGFX Generated Code Building on STM32Cube IDE.

I am working on below setup:

Software Tool Chain:

STM32CubeMX 5.6.0

TouchGFX 4.13.0 Designer

STM32CubeIDE 1.3.0

Hardware:

STM32F746G-DISCO (Discovery Board)

I have created GUI on TouchGFX 4.13.0. worked fine on simulator and Discovery Board as well.

I am doing as below :

Open TouchGFX:

1. File->New

2. Select Application Template STM32F746G Discovery Kit

3. Select UI Template -> Blank UI

4. Name the project TestHardware and Click Create

5. Add a Red box that fills with rectangle and the entire canvas.

6. Add a button that I can click

7. Click Generate Code

8. Click Run Target

This does work, and I get the desired Red box and single button that I can click.

When I am trying to Open In STM32CubeIDE 1.3.0 and Import as per below:

C:\TouchGFXProjects\TestHardware\STM32CubeIDE

Binary File Created in Too Large ..

1) STM32F746G_DISCO.bin        2.12 GB

STM32F746G_DISCO.elf         239 KB

STM32F746G_DISCO.hex         99 KB

2) STM32CubeIDE Debugger Error !!

(Read) Failed determine breakpoint type

Error ! Failed to read target status

Debugger connection lost.

Shutting down . . .

3) STM32CubeProgrammer 2.4.0 also have Error while programming .But The TouchGFX Generated File works Well.

4) Changing the STM32F746NGHx_FLASH.ld (from Repository Demo of specific board ) reduce the file size to 35KB . But Code did not work on target either Debug Mode receive error at mention 2) nor the STM32CubeProgrammer/ST-Link.

Is this is Bug or I am using something wrong. ? Please advice me ..

Thanks in advance

@Community member​,

You simply need the stm32f746*.s file in your CubeIDE project. It's missing from the AT. I fixed it but forgot to upload the AT - I'll rectify this asap. Until then, just include the .s file - it's because Eclipse based ides define weak symbols for parts of the .s file including reset_handler

Unfortunately i'm missing an F746G-DISCO board at home so i can't test it - I think that's why i hadn't uploaded it yet :)

But if you're interested in helping me test it, let me know.

Sure I will ..

Can you let me know where should I copy startup_stm32f746nghx.s from ?

As for now .. I have just copied

 from 

C:\TouchGFXProjects\MyApplication_9\gcc

to

C:\TouchGFXProjects\MyApplication_9\STM32CubeIDE

Debugger Start .. Now .. But Reached on HardFault..

Seen Old Complied Project on Screen

Thanks for your concern ..

Also Please more attention on the size of .bin in screenshot..

.bin files will be huge because they're covering memory area all the way up to external flash 0x90000000. That's a lot of 0s !

[Martin KJELDSEN]

Just get it from a CubeMX generated F746 project. Or from Cube FW packs.

It's not 100% clear to me how you created this project. Check that CRC is enabled in CubeMX - otherwise it will hardfault.

[Martin KJELDSEN]

If not CRC, then you'll need to show me more stack trace.

@Martin KJELDSEN (ST Employee)

OK .

startup_stm32f746xx copied from.

C:\Users\Gurpreet\STM32Cube\Repository\STM32Cube_FW_F7_V1.16.0

I have created Project from TouchGFX 4.13.0 . The Steps Mentioned by Alexandre RENOUX (ST Employee)

Yes .. CRC is Already Enabled ..

Still Having HardFault ..

[Karan 123]

How I will ?

[Karan 123]

Is this a Bug or What ?? How do I resolved that .. ?

or In which version TouchGFX team will be corrected ?
