Missing entry for OctoSPI in PeriphClockSelection in PeriphCommonClock_Config for STM32H7A3

[GS1]

In CubeMX 6.5.0. I detected a missing clock specification for OctoSPI:

void PeriphCommonClock_Config(void)

{

 RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};

 /** Initializes the peripherals clock

 */

 PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_ADC|RCC_PERIPHCLK_SPI3

                             |RCC_PERIPHCLK_SPI2|RCC_PERIPHCLK_SPI1

                             |RCC_PERIPHCLK_UART8|RCC_PERIPHCLK_FDCAN

                             |RCC_PERIPHCLK_USART6|RCC_PERIPHCLK_UART7

                             |RCC_PERIPHCLK_UART4|RCC_PERIPHCLK_USART3

| RCC_PERIPHCLK_OSPI; // <<< is missing !!!

 PeriphClkInitStruct.PLL2.PLL2M = 4;

 PeriphClkInitStruct.PLL2.PLL2N = 200;

 PeriphClkInitStruct.PLL2.PLL2P = 10;

 PeriphClkInitStruct.PLL2.PLL2Q = 5;

 PeriphClkInitStruct.PLL2.PLL2R = 4;

 PeriphClkInitStruct.PLL2.PLL2RGE = RCC_PLL2VCIRANGE_1;

 PeriphClkInitStruct.PLL2.PLL2VCOSEL = RCC_PLL2VCOWIDE;

 PeriphClkInitStruct.PLL2.PLL2FRACN = 0;

 PeriphClkInitStruct.PLL3.PLL3M = 2;

 PeriphClkInitStruct.PLL3.PLL3N = 100;

 PeriphClkInitStruct.PLL3.PLL3P = 2;

 PeriphClkInitStruct.PLL3.PLL3Q = 2;

 PeriphClkInitStruct.PLL3.PLL3R = 2;

 PeriphClkInitStruct.PLL3.PLL3RGE = RCC_PLL3VCIRANGE_2;

 PeriphClkInitStruct.PLL3.PLL3VCOSEL = RCC_PLL3VCOWIDE;

 PeriphClkInitStruct.PLL3.PLL3FRACN = 0;

 PeriphClkInitStruct.OspiClockSelection = RCC_OSPICLKSOURCE_PLL2;

 PeriphClkInitStruct.Spi123ClockSelection = RCC_SPI123CLKSOURCE_PLL3;

 PeriphClkInitStruct.FdcanClockSelection = RCC_FDCANCLKSOURCE_PLL2;

 PeriphClkInitStruct.Usart234578ClockSelection = RCC_USART234578CLKSOURCE_PLL3;

 PeriphClkInitStruct.Usart16ClockSelection = RCC_USART16910CLKSOURCE_PLL3;

 PeriphClkInitStruct.AdcClockSelection = RCC_ADCCLKSOURCE_PLL2;

 if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)

 {

   Error_Handler();

 }

}

Please correct in next release of CubeMX.

Hello,

Thank you for reporting that,

Could you share an ioc file that highlights the issue ?

Hello Mike,

please see attached the IOC where the clock reference is missing. Clocksource is selected to PLL2R for OCTOSPI.

On the other hand:

In case I change the clocksource to PLL1Q, the clock initialisation is included in the OctoSPI initialisation and is done correctly. But it then no longer appears in the PeriphCommonClock_Config.

Thank you very much for your input,

From our database, I think the issue has been already spotted, and a fix expected for 6.6.0.

Anyways, I entered a ticket, and hopefully the fix will be validated against your input as well.

Again thank you.
