Dear STMicro staff,

I found a bug in CubeMX, so I want you to fix this bug.

Device : STM32F429IEHx
Peripheral : Master Clock Output

In HAL_RCC_MCOConfig(), MCO pin's speed is set in GPIO_SPEED_FREQ_VERY_HIGH.
But after that, MX_GPIO_Init() is called, and the function changes the speed into GPIO_SPEED_FREQ_LOW.
Because of this speed change, Highly frequency clock won't be output from MCO port.

I hope this information will help you improve your products.

Yours faithfully,
