Enabling low level driver for one peripheral, includes the low level driver for RCC in GPDSC project.

But main.c contains code for the high level RCC access. Tested with CubeMX 5.6.1 and STM32L452VCT

Changing RCC also to the low level driver, includes the RCC HAL driver to the project, but main.c contains the low level access

HAL and LL are not independent. HAL often uses LL, and LL sometimes uses HAL. STMCubeMX does a pretty good job of only including those files that it needs, but it's possible one was included without being needed. Delete it and see if any errors pop up.

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.
