I have just updated one of my projects to STM32F1 FW 1.6.0, and my code was not able to compiled anymore. IOC file attached.
Here is my clocking scheme:
As you can see the LSI oscillator is not used, so I assume this is why the LSI_VALUE is not generated to the stm32f1xx_hal_rcc.h file. However the LSI_VALUE constant is still used in the stm32f1xx_hal_rcc_ex.c:
case RCC_PERIPHCLK_RTC:
{
/* Get RCC BDCR configuration ------------------------------------------------------*/
temp_reg = RCC->BDCR;
/* Check if LSE is ready if RTC clock selection is LSE */
if (((temp_reg & RCC_BDCR_RTCSEL) == RCC_RTCCLKSOURCE_LSE) && (HAL_IS_BIT_SET(temp_reg, RCC_BDCR_LSERDY)))
{
frequency = LSE_VALUE;
}
/* Check if LSI is ready if RTC clock selection is LSI */
else if (((temp_reg & RCC_BDCR_RTCSEL) == RCC_RTCCLKSOURCE_LSI) && (HAL_IS_BIT_SET(RCC->CSR, RCC_CSR_LSIRDY)))
{
frequency = LSI_VALUE;
}
else if (((temp_reg & RCC_BDCR_RTCSEL) == RCC_RTCCLKSOURCE_HSE_DIV128) && (HAL_IS_BIT_SET(RCC->CR, RCC_CR_HSERDY)))
{
frequency = HSE_VALUE / 128U;
}
/* Clock not enabled for RTC*/
else
{
frequency = 0U;
}

Hello
garsi.khouloud
,I have created a blank project for the same MCU, and it does not generate the LSI value constant.
I have forgotten to mention that I am running the CubeMX under Linux. I think it should not matter, but it seems to be.
