Linker errors and "Run target" fails

[idrissmc]

hi everyone,

i wanted to create a project with touchGFX but there are errors, i just create the graphic interface, i didn't add any code!

even though when i tried to upload to my card an example it said error too!

how can i resolve this?

 

[Martin KJELDSEN]

Please show me the log from the designer on why "run target" fails - Which board is this? You need ST-Link installed, and you haven't, is my guess.

As far as your linker issues - Looks like the generated image code has not been added to your project. This looks like Keil - Did you simply start from an Application template? The "Generate" code button should update the project with new files but you can add them manually - I'm not sure what could be wrong with that - but "Generate code" will fail if it cannot execute its "post generate command".

hi @Martin KJELDSEN​,

i use the F746G-disco board, I have cubeProgrammer installed, I found the trick but now i have an other problem, PostGenerateCommand "echo test" i put.

so, I created a project on cubeIDE, I added TouchGFX on the middleware, then I executed TouchGFX Designer, I created 2 screen to test, Then I opened again Cube IDE, and here the errors.

I use Cube IDE 1.0.2 and touchGFX 4.13.0

N.B.: I tried to exclude simulators files as someone did on a tutorial but it didn’t work!

is there any documents?

you'll have to have ST-Link installed. It's not the same as the cubeProgrammer (although it might rely on ST-Link as well? I'm not completely sure)

It seems that you have followed a guide for an old version of TouchGFX. Be aware that the 4.13.0 have significant enhancements and changes that most likely render the 'old' method obsolete.

hi @Martin KJELDSEN​ 

I got 1 error now, please help, I can't understand how to make .elf

It said cannot find -llibtouchgfx-float-abi-hard

[Martin KJELDSEN]

There's a linker error somewhere - Can you show me a bit further up the log window?

I found it i add it but it still the same error

Just created a project that links fine (CubeIDE 1.2.0)

* CubeMX Project Generator - Toolchain: CubeIDE

* Generate code

* Open part-file in TouchGFX Designer - Generate code

* Refresh project in CubeIDE and build

Hi @Martin KJELDSEN​ , the problem i’ve installed cubeIDE 1.2.0 but in middleware there’s no graphics any more, so can you tell me how to open touchgfx directly from CubeMX (execute : as the previous version), I have to select additional software then activate graphics touchgfx & then how to open touchgfx?

thank you

[Martin KJELDSEN]

Please read the sticky on installing and using X-CUBE-TOUCHGFX 4.13.0. TouchGFX Graphics middleware is no more as of CubeMX 5.5.0 (it had too many restrictions on required hardware).

Hi @Martin KJELDSEN​ ,

i can now debug into QSPI, but when I created some images on TouchGFX, I can’t see them on the LCD when I debug but I still see texts and backgrounds made of boxes, only when I add images I can’t see them on the board, what do you think it could be the problem? :thinking_face:

[Martin KJELDSEN]

Did you program the external flash? you need to specify a flashloader for that particular chip through stlink or stcubeprogrammer.

[idrissmc]

Yes @Martin KJELDSEN​ i did it, it works now but I think I have to program QUADSPI through CubeMX and not leave the default settings, when I did that it works, if I understand maybe when I generate code , the sittings (of QSPI) will interact with an other file(Im not sure) but when modify the prescaler and fifo it works, but I still not understanding what’s the flash size? I put 24 but 24 isn’t the size of the external flash! :thinking_face:
