But main.c contains code for the high level RCC access. Tested with CubeMX 5.6.1 and STM32L452VCTChanging RCC also to the low level driver, includes the RCC HAL driver to the project, but main.c contains the low level access
The problem is that, despite selecting the HAL driver in the project manager settings, the RCC HAL drivers are not included in the project file (GPDSC). Only the LL drivers are included.
