CMSIS headers define LTDC_Layer2, but LTDC_Layer2_BASE doesn't exist #26

Describe the set-up

Include stm32l4p5xx.h header
Try to use LTDC_Layer2 definition

Describe the bug Compilation fails since there's no definition for LTDC_Layer2_BASE.

Hi @benedekkupper,

Thank you for this report. According to the reference manual RM0432, we have only one layer for STM32L4P5xx/ STM32L4Q5xx and two layers for STM32L4R7xx/STM32L4R9xx and STM32L4S7xx/STM32L4S9xx.

The reported point has been forwarded to our development teams and see if there is an update in the stm32l4p5xx.h and stm32l4q5xx.h files to correspond the reference manual. We will get back to you as soon as they provide us with their feedback.

Will keep you informed.

With regards,

Hi @benedekkupper,

Thank you for this report. The issue has been confirmed by our development teams. The LTDC_Layer2 definition will be removed from the stm32l4p5xx.h and stm32l4q5xx.h CMSIS files. This fix will be made available in a future version. Thank you again.

Thank you again for your contribution.

With regards,
