I updated to TouchGFX 4.19.0 -> 4.20.0 and get this linker error. I cannot figure out how to fix it. Everything compiles successfully, but linker fails.

Found solution, I did not generate code with CubeMX, only with Designer.

When updating, make sure you generate with both.

    I want to move my project to TouchGFX 4.20 from TouchGFX 4.18. 

    But I allways take a error in IDE.

    I uptaded MX, IDE and TouchGFX.

    I opened project on MX. I selected TouchGFX 4.20 on Software Packs. And i generate, it open on IDE and I build all in IDE. So everything perfect.

    But I must change GUI on the Touch GFX. For example I add pushbutton. I generate code in Touch GFX. Then i opened the project for writting the code in IDE. I build all in IDE but it gives error(linker).

    I use this current version:

    Touch GFX 4.20, IDE 1.10.1, MX 6.6.1

    Hello,

    Could you explain which issue you are facing exactly ? There are multiple ones here. The initial one was that the user did not regenerate code from STM32CubeMX which is always recommended as there might be important changes between library versions, in this case the painter implementation. You can find more on the release posts on this forum or on the online documentation as well when there are known bugs.

    If you are facing another type of issue please create another post for better visibility so that other users or st employees can help you. I would suggest contacting your local ST contacts if you have issues as this is a forum, we try to answer as much as we can but cannot find answer/find solution for every post.
