When using L496 Application Template, CubeMX wipes out LCD_IO code from TouchGFXGeneratedHAL upon first trivial code generation

Michael K · ‎2021-09-03

Title says it all. Steps to reproduce:

Create new project with L496 Disco Application Template
Open Project In CubeIDE, verify build OK
Open IOC in CubeMX. Change nothing, but click the Generate Code button. (Note that there is still an error in TouchGFX generator, generate anyway)
Build again, observe linker errors.

See image attached for code diff. Why is this happening? How can I prevent it?

I can use my version control to revert that section of the code, but I have to do it every time I regenerate the ioc :(

Hi,

This is intriguing as I do not face it. What versions of STM32CubeMX and TouchGFX are you using ? What is the revision of your STM32L496 discovery board ? In my case, TouchGFX 4.17, STM32CubeMX 6.3 and revision MB1261 B-0. The section of the code in red is not removed in my case.

What is the error you face in TouchGFX Generator ? Could you maybe share screenshots or your project ?
