In STM32-G0B1RE, I have an issue of SPI peripheral clock configuration and clock initialization.

[Grace_04]

I'm trying to communicate with external device using SPI, but I'm not getting any SPI peripheral clock at configuration level and there is no clock initialization details in SPI Init(); 

void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)

{

GPIO_InitTypeDef GPIO_InitStruct = {0};

if(hspi->Instance==SPI1)

{

/* USER CODE BEGIN SPI1_MspInit 0 */

/* USER CODE END SPI1_MspInit 0 */

/* Peripheral clock enable */

__HAL_RCC_SPI1_CLK_ENABLE();

__HAL_RCC_GPIOA_CLK_ENABLE();

/**SPI1 GPIO Configuration

PA1 ------> SPI1_SCK

PA6 ------> SPI1_MISO

PA7 ------> SPI1_MOSI

*/

GPIO_InitStruct.Pin = GPIO_PIN_1|GPIO_PIN_6|GPIO_PIN_7;

GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;

GPIO_InitStruct.Pull = GPIO_NOPULL;

GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;

GPIO_InitStruct.Alternate = GPIO_AF0_SPI1;

HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

/* USER CODE BEGIN SPI1_MspInit 1 */

/* USER CODE END SPI1_MspInit 1 */

}

}

I'm not sure what you're showing us here, perhaps a misunderstanding?

HAL_SPI_MspInit initializes the pins, that's it. The peripheral initialization will be in MX_SPI1_Init which calls HAL_SPI_Init. The function MX_SPI1_Init should be in main.c.
