STM32MP25 CubeMX RCC Warning when HSE set to Crystal/Ceramic Resonator

Description of the Issue

I am experiencing a configuration validation warning related to RCC when generating code in STM32CubeMX version 6.15.0 for the STM32MP257DAK3 MPU. Although the code can be generated, CubeMX reports the following RCC warning during validation:

 

 
Main Config: These peripherals still have some not configured or wrong parameter values: [RCC]

This warning appears even when the RCC configuration seems complete and valid.


Steps to Reproduce

  1. Open STM32CubeMX v6.15.0

  2. Create a new project for STM32MP257DAK3

  3. Navigate to System Core → RCC

  4. Set HSE to Crystal/Ceramic Resonator

  5. Click GENERATE CODE

  6. CubeMX displays the above warning during pre-generation configuration check

  7. I've selected Pin Context Assignment from the dropdown menu, but it's empty.
