Hello Community,i have the strange behavior that the Clockswitch to HSE does not work in STM32L051. __HAL_RCC_SYSCLK_CONFIG(RCC_ClkInitStruct->SYSCLKSource); /* Get Start Tick */ tickstart = HAL_GetTick(); if(RCC_ClkInitStruct->SYS...

Hello Community,i have an empty project with STM32L051R8 MCU.Project was created with CubeIDE Version: 1.8.0Build: 11526_20211125_0815Only the OscillatorPins for external 8MHz crystal, RCC_MCO and SWDIO+SWCLK have been configured.HSE is used for PLL ...

Failure found, was a Misstypo in SCM -> wrong µC in project.Stay Healthy Martin

Additional Information: Understood the bitmasking for Value "8" and Code Line__HAL_RCC_GET_SYSCLK_SOURCE() ((uint32_t)(READ_BIT(RCC->CFGR,RCC_CFGR_SWS)))We check HW and come back again

OK Finally failure found.reason was a floating level @boot0-Pinmany thanks for the helpBR'sMartin

I will check Flash wait states...HSE starts and SysTickTimer is counting. it seems no SysTickInterrupt is thrown?see picture below

External XTAL works as expected. and configuration is as in the picture shown.
