Same bug here. Here's my notes for the workaround which works great at least until this gets resolved.

Steps needs to be followed in the order below... I've numbered them to help with that.

Step 1: Create a New STM32CubeIDE Project

1) In STM32CubeIDE > File > New > Select Part Number > Next > Set ProjectName > Click Finish

2) Enable SYS > Serial Wire (other configs can be made later)

3) Save and close ProjectName.IOC

4) Build Project (Compiling should be successful!)

Step 2: Add TouchGFX 4.17 to the Project

5) Open ProjectName.IOC > Enable CRC > Software Packs > Select Component > TouchGFX 4.17

6) Expand Software Packs > Enable Graphic Application > *LEAVE ALL TouchGFX SETTINGS TO DEFAULT*

7) Save and close IOC *DO NOT BUILD THE PROJECT *

Step 3: Generate TouchGFX 4.17 Templates

8) Double-click on \TouchGFX\ApplicationTemplate.touchgfx.part

9) Select "Blank UI" > Click red Import button > Click Generate Code > Close Designer using the X

Step 4: Clean & Compile Project

10) Right-click ProjectName > Select "Clean Project"

11) Right-click ProjectName > Select "Build Project" (Compiling should be successful at this stage!)

Step 5: ToughGFX Configurations and Code generation

12) Open ProjectName.IOC > Software Packs > TouchGFX > Set Screen Resolution e.g. 240x240, etc

13) Double-click on \TouchGFX\ApplicationTemplate.touchgfx.part, Click Generate Code > Close Designer using the X

14) Right-click ProjectName > Select "Clean Project"

15) Right-click ProjectName > Select "Build Project" (Compiling should be successful at this stage!)

done!

Note: If Partial Buffer is required and selected in the TouchGFX configs:

16) Move attached "TouchGFX_DataTransfer.h" and "TouchGFX_DataTransfer.c" into the \TouchGFX\target\ folder

17) CLEAN PROJECT and Build Project

Hi. You are correct. Well, half-correct rather! You had me doubting and so I've tried those steps to find out it does not work for every parts. For instance the built failed for a STM32F412RGT6 however it did worked perfectly fine for a STM32H743VIT6.

I'm attaching the successful built (STM32H743VIT6) following the steps above. I've cleaned the project, see if you can build it.

ps. For the record; the STM32F412RGT6 failed build I'm getting the following errors:

1) undefined reference to `touchgfx_init'

2) undefined reference to `touchgfx_taskEntry'

Environment:

  • STM32CubeIDE Version: 1.7.0 Build: 10852_20210715_0634 (UTC)
  • TouchGFX 4.17.0
