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

I have the same question, can we get one of the experts in on this. I have moved the project to 4.15 / 1.5 it compiles and runs on the old board.

CubeMX is not happy about it so I need to make that migration also.

Then I want to move it all to the H735 board. I think I can port over all my code additions. Its the touchGFx stuff, how does one migrate?

Any hints?

Another detail is that I'm using 4.14 touchGFX version, CubeMx 6.1 and CubeIDE 1.4

Hi,

The STM32H735-dk application template can only be selected in TouchGFX Designer 4.15

When you say migrate, do you wish to only migrate the UI you have made for your project on the STM32F746-dk ?

Yes I mean this! Just to migrate the UI interface I made to the STm32H735-Dk and load it to the display from touchGFX run Target. But another question...I can't download touchGFX 4.15, I can just adding it from CubeMX..

[Romain DIELEMAN]

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

In general when you have an "empty" project for a board, you can import the gui part of an older project using the Designer. In Edit menu, find import. Then click Browse and find your old project.touchgfx file.

Thanks

Yes I've seen this, but since the template for STM32H735G-DK can only be selected in TouchGFX designer 4.15 and I can't download it from :

https://www.st.com/en/development-tools/touchgfxdesigner.html

How can I do this step? Actually I need just to load the UI I've done with the STM32F746-DK to the new H7-DK from touchGFX designer

[Flemming Gram CHRISTENSEN]

Hi. Try again. If you do not select a version explicitly, you will get 4.15 (I just tried).

Thanks.

[Giovanni Cambareri]

Yes...thanks! As you told I've tried to select the 4.15.... Now I can download it.

But I've a problem...I've imported the previous UI to the 4.15 and if i run the target I've got this error:

 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

I am not sure, so I will let others answer.

But to progress I would start CubeProgrammer manually, select the external loader, find the .hex file, and program.

If it works, then it can also be done from the command line.

Have a nice day.
