Multiple linker symbol error after update to CubeMX 6.9.0

[JojoS]

After Upgrading to Cube 1.13.0 with CubeMX6.9.0, my project is no longer compatible with CubeMX 6.8.1.

When I start the CodeGenerator, it creates a file \Drivers\CMSIS\Device\ST\STM32H7xx\Source\Templates\system_stm32h7xx.c
which is a duplicate for the file in core/src.
It has some changes, how to handle this situation? Why is this template generated?

Hello

For some reason this has sometimes happen to me also with earlier CubeMx versions when update project. You can select \Drivers\CMSIS\Device\ST\STM32H7xx\Source\Templates\system_stm32h7xx.c file properties and from C/C++ Build page select 'exclude resource from build'.
