CubeMx 4.22.1 code generation issue in SystemClock_Config

[Stephane Bonnot]

With STM32Cube_FW_L4_V1.9.0 when generating code using PLL (HSE or other), SystemClock_Config(void) is missing a diviser :

RCC_OscInitStruct.PLL.PLLM is not set and thus generates an issue ( default value is 0)

adding  RCC_OscInitStruct.PLL.PLLM = 1; // (or any value set in CubeMx) 

solves the issue.

#4.22.1 #stm32-l4 #cubemx

Hello

Bonnot.Stephane

,

Please use the last version of CubeMx 4.

This issue about 'PLLM is no more generated' is fixed in the CubeMx version 4.23 asmentioned in the Release note of STM32CubeMX
