STM32CubeMX Generating Incorrect Code for Clock Configuration

[Terence D]

Posted on September 27, 2017 at 23:56

I've used the STM32CubeMX application to setup the main PLL and PLLI2S as shown below:

When I generate the code, it generates the following:

PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_I2S;

PeriphClkInitStruct.PLLI2S.PLLI2SN = 123;

PeriphClkInitStruct.PLLI2S.PLLI2SM = 8;   // <--- Compilation failure, PLLI2SM is not structure element

PeriphClkInitStruct.PLLI2S.PLLI2SR = 5;

PeriphClkInitStruct.I2SClockSelection = I2S_CLOCK_PLL;  

// <-- I2SClockSelection is not a struct element

if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)

{

_Error_Handler(__FILE__, __LINE__);

}

As shown in the comments in the code above, both PLLI2SM and I2SClockSelection are not members of their respective structures.  This results in a compilation failure...  Anyone know what's going on here?

Hi Imen - I'm using STM32CubeMX Version 4.1, STM32Cibe V1.0. I've attached my ioc file.

Hi

tmdarwen

,

Thanks for sharing this issue.

I checked and confirm the error for

PLLI2SM and I2SClockSelection.

I raised thisissue internally to CubeMx team tofix it.

Thanks and Best Regards

Hello

tmdarwen

,

Just to be precise, this issue was solved in CubeMX4.

You can upgrade your CubeMX with the latest (cubeMX4.24).
