Bug of MCO Pin configuration by CubeMX

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,

F.Nimura

Hi F.Nimura,

Thank you for your feedback. The issue has been reported internally.-Syrine-

Hi F.Nimura,

GPIO_Init uses GPIO_InitStruct.

Its settings are coming from the Configuration Tab->GPIO.

In this window, you have to select the needed output speed for RCC_MCO_1.

Could you please confirm which settings are in use in that window ?
