STM32H750 cubeMX : VREF clock not enabled before calling HAL_SYSCFG_EnableVREFBUF() in HAL_MspInit()
I think there is a mistake in cubeMX generated HAL_MspInit() when using VREFBuf:
at firmware startup, HAL_MspInit() calls HAL_SYSCFG_EnableVREFBUF() but the clock of VRREFBuf is not enabled before, so it fails in timeout.
To fix this I have added call of HAL_SYSCFG_EnableVREFBUF(); at the begining og HAL_MspInit() user code.
