Migrate project from STM32F746G-disco to STM32H735-DK

[Giovanni Cambareri]

Hi, which is the fastest way to migrate a touchGFX project from  STM32F746G-disco to STM32H735-DK? Actually on touchGFX application template I can't choose the STM32H735-DK.

I will glad if someone could help me

Hi,

What version of STM32CubeProgrammer are you using ?

/Romain

[Giovanni Cambareri]

The last version of CubeProgrammer.

But the error comes out if I run the target from TouchGFx.

Now I will try from CubeProgrammer

Like Flemming said, you can use the "Import Gui" option in the "Edit" tab in Designer to migrate the UI interface. Once you enter the "Import GUI window", press the Browse button and navigate to the project folder where you developed your UI (on the F746-disco board I presume). Navigate to the TouchGFX folder of that project, and open the TouchGFX project.

Yes , I've already done this .

But I've got this error when i run the target from touchGFX designer:

Error: external loader C:\Program Files (x86)\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\ExternalLoader\MX25LM51245G_STM32H735G-DK.stldr cannot be loaded.

    make[1]: *** [_extflash_] Error 1

    gcc/Makefile:288: recipe for target '_extflash_' failed

    ../gcc/Makefile:52: recipe for target 'flash' failed

    make: *** [flash] Error 2

    Failed

  Failed

Any idea how to solve this? thanks a lot

[Giovanni Cambareri]

I've tried from CubeProgrammer and it works! Thanks a lot!

But I would like to understand why I can't do it from TouchGFX Designer

Hi,

TouchGFX Designer uses CubeProgrammer to run on target the project, but the latest version (CubeProgrammer 2.6) is having issues out of our reach. The error you shared shows that the issue comes from the external loader not being found/open within CubeProgrammer, and therefor the external flash could not be run.

Could you try to run your project from TouchGFX Designer with CubeProgrammer 2.5 installed to see if it fixes this issue ?

Hi,

I've just tried installing CubeProgrammer 2.5 and run target but I've noticed from touchGFX designer log this thing:

As you can see touchGFX uses CubeProgrammer 2.4 even if I've installed 2.5 or 2.6 version.

Here the log from touchGFX Designer:

I will assume it is the same issue I had a few weeks ago. I had an issue with CubeProgrammer 2.4 which was in my Program Files (x86)\ folder, while my CubeProgrammer 2.5 was in Program Files\. As of now, the makefile looks first for the CubeProgrammer version in the x86 fodler, then looks at another location if it cannot find any. This will be soon updated to reverse the search order to prevent this kind of issues.

• go to C:\Program Files (x86)\STMicroelectronics\STM32CubeProgrammer
• make sure it is the version 2.4 (open the /bin folder and open the STM32CubeProgrammer.exe or right click on it to look at its properties
• If it is the 2.4, uninstall it

[Giovanni Cambareri]

It works, thanks a lot and have a nice day!

[Romain DIELEMAN]

Great to hear !!

This is an annoying issue which like I said we will try to fix soon (or at least an "automatic work-around").

I faced that issue while working on the F756 eval board and banged my head on the table a couple of times trying to fix it. CubeProgrammer with Designer 2.4 worked fine on other boards for me so it took a lot of testing before I found that solution... (also had other errors ofc :sad_but_relieved_face: )

Have a nice day as well,
