how to configure HSI in STM32L5...

[DYann.1]

Hello,

I would like to know if it's possible to configure my evaluation board HSI, I have this code and I would like to adapt it on my evaluation card and see if it is compatible with the rest :

// HSI
//
void SystemClock_Config(void)
    {

    RCC_OscInitTypeDef RCC_OscInitStruct =
	{ 
	0
	};
    RCC_ClkInitTypeDef RCC_ClkInitStruct =
	{
	0
	};

    /** Configure the main internal regulator output voltage
     */
    if (HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE0) != HAL_OK)
	{
	Error_Handler();
	}

    /** Initializes the RCC Oscillators according to the specified parameters
     * in the RCC_OscInitTypeDef structure.
     */
    RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI
	    | RCC_OSCILLATORTYPE_HSI48 | RCC_OSCILLATORTYPE_LSE
	    | RCC_OSCILLATORTYPE_LSI | RCC_OSCILLATORTYPE_MSI;
    RCC_OscInitStruct.LSEState =  RCC_LSE_BYPASS;
    RCC_OscInitStruct.HSIState = RCC_HSI_ON;
    RCC_OscInitStruct.HSI48State = RCC_HSI48_ON;
    RCC_OscInitStruct.LSIDiv = RCC_LSI_DIV1;
    RCC_OscInitStruct.LSIState = RCC_LSI_ON;
    RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
    RCC_OscInitStruct.MSIState = RCC_MSI_ON;
    RCC_OscInitStruct.MSICalibrationValue = RCC_MSICALIBRATION_DEFAULT;
    RCC_OscInitStruct.MSIClockRange = RCC_MSIRANGE_6;
    RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
    RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI;
    RCC_OscInitStruct.PLL.PLLM = 2;
    RCC_OscInitStruct.PLL.PLLN = 23;
    RCC_OscInitStruct.PLL.PLLR = RCC_PLLR_DIV8;
    RCC_OscInitStruct.PLL.PLLQ = RCC_PLLQ_DIV2;
    RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV7;
    if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
	{
	Error_Handler();
	}

    /** Initializes the CPU, AHB and APB buses clocks
     */
    RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_SYSCLK
	    | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2;
    RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
    RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
    RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
    RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

    if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_5) != HAL_OK)
	{
	Error_Handler();
	}

    /** Enable MSI Auto calibration
     */
    HAL_RCCEx_EnableMSIPLLMode();

    /** MCO configuration
     */
    HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_SYSCLK, RCC_MCODIV_1);

    //__HAL_RCC_PWR_CLK_ENABLE();
    }

With the .ioc file, it's better for understanding.

Thank you for your helps.

I saw your zip file. Did you see my answer?

As I said, you will have to use LSI as a clock source to something if you want CubeMX to enable it. Otherwise it is not needed and will not be enabled.

Yes it's the case with my _HSI_conf project (in projet I have the .ioc file) but I don't have the same code. What I would like to obtain 

    RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI
	    | RCC_OSCILLATORTYPE_HSI48 | RCC_OSCILLATORTYPE_LSE
	    | RCC_OSCILLATORTYPE_LSI | RCC_OSCILLATORTYPE_MSI;

And with  _HSI_conf project I have this code :

 RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI48|RCC_OSCILLATORTYPE_HSI
                              |RCC_OSCILLATORTYPE_LSE|RCC_OSCILLATORTYPE_MSI;

I'm missing the RCC OSCILLATOR TYPE LSI line

Always very vague and evasive, nothing concrete. Can you modify my .ioc file in my _HSI_conf projet and show me the generated code ?

And I have this code

 RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI48|RCC_OSCILLATORTYPE_HSI
                              |RCC_OSCILLATORTYPE_LSI|RCC_OSCILLATORTYPE_MSI;

And this is the code I am waiting for :

    /** Initializes the RCC Oscillators according to the specified parameters
     * in the RCC_OscInitTypeDef structure.
     */
    RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI
	    | RCC_OSCILLATORTYPE_HSI48 | RCC_OSCILLATORTYPE_LSE
	    | RCC_OSCILLATORTYPE_LSI | RCC_OSCILLATORTYPE_MSI;

I'm missing the RCC_OSCILLATORTYPE_LSE line
