Hello,

Replace manually the Flash latency from 0 to 3: FLASH_LATENCY_3

  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK)

by

  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_3) != HAL_OK)

As CubeMx don't let you change it, I need to check internally if it's an issue or not.

Hello,

Getting back to you regarding CubeMx. There is an issue in CubeMx V6.12.1.

For System clock @240MHz/VOS2, the HPRE prescaler needs to be  2.

So in your ioc file set HPRE to 2 instead of 1.

The issue seems to be fixed in an internal version that will be available soon on st.com.

If this solved your issue/answered your question, please accept it as solution.

Thank you.
