There is a bug in stm32l1xx_hal_conf.h. The MSI_VALUE value is wrong.

[MSipo]

DeviceId = STM32L151RETx

FirmwarePackage = STM32Cube FW_L1 V1.10.2

Bug in: stm32l1xx_hal_conf.h

On row 110. The MSI_VALUE is defined as 16000000. It should be defined as 2097152 Hz

/**
 * @brief Internal Multiple Speed oscillator (MSI) default value.
 * This value is the default MSI range value after Reset.
 */
#if !defined (MSI_VALUE)
 #define MSI_VALUE ((uint32_t)16000000) /*!< Value of the Internal oscillator in Hz*/
#endif /* MSI_VALUE */

Hello @Community member​ ,

I found different define in the latest firmware package that you may want to check out:

/**
 * @brief Internal Multiple Speed oscillator (MSI) default value.
 * This value is the default MSI range value after Reset.
 */
#if !defined (MSI_VALUE)
#define MSI_VALUE (2097000U) /*!< Value of the Internal oscillator in Hz*/
#endif /* MSI_VALUE */
 

Please make sure to use the latest release of STM32CubeL1 V1.10.2, then keep me infomed about your update.

Hi @Community member​ ,

After check, it seems the error is in the template stm32l1xx_hal_conf.h when using CubeMX tool, which is not aligned with the HAL package.

 #if !defined (MSI_VALUE)
 #define MSI_VALUE ((uint32_t)16000000) /*!< Value of the Internal oscillator in Hz*/
#endif /* MSI_VALUE */
 

I have passed your feedback along to our CubeMX team for fix.

Thank you for bringing this issue to our attention.
