[Issue] CubeMx Assert failed with I2C Low Layer

We encountered a problem with CubeMx and I2C Low Layer libraray on an STM32F413RH.

The code fall in an assertion.

The initialization from CubeMx :

  I2C_InitStruct.PeripheralMode = LL_I2C_MODE_I2C;

  I2C_InitStruct.ClockSpeed = 100000;  I2C_InitStruct.DutyCycle = LL_I2C_DUTYCYCLE_2;  I2C_InitStruct.OwnAddress1 = 0;  I2C_InitStruct.TypeAcknowledge = LL_I2C_ACK;  I2C_InitStruct.OwnAddrSize = LL_I2C_OWNADDRESS1_7BIT;  LL_I2C_Init(I2C1, &I2C_InitStruct);

The assertion in stm32f4xx_ll_i2c.c, line 173:

uint32_t LL_I2C_Init(I2C_TypeDef *I2Cx, LL_I2C_InitTypeDef *I2C_InitStruct)

{  LL_RCC_ClocksTypeDef rcc_clocks;  /* Check the I2C Instance I2Cx */  assert_param(IS_I2C_ALL_INSTANCE(I2Cx));  /* Check the I2C parameters from I2C_InitStruct */  assert_param(IS_LL_I2C_PERIPHERAL_MODE(I2C_InitStruct->PeripheralMode));  assert_param(IS_LL_I2C_CLOCK_SPEED(I2C_InitStruct->ClockSpeed));  assert_param(IS_LL_I2C_DUTY_CYCLE(I2C_InitStruct->DutyCycle));&sharpif  defined(I2C_FLTR_ANOFF)&&defined(I2C_FLTR_DNF)  assert_param(IS_LL_I2C_ANALOG_FILTER(I2C_InitStruct->AnalogFilter)); // failed here  assert_param(IS_LL_I2C_DIGITAL_FILTER(I2C_InitStruct->DigitalFilter));&sharpendif

CubeMx version 4.25.0

Package STM32Cube FW_F4 V1.21.0

Hi Nicola,

Could you please share your ioc file. This will help us for the debug.

Thanks!

Khouloud.

Done.

The problem is that the AnalogFilter and DigitalFilter in the struct are not initialized, so it can contain anything.

A call to LL_I2C_StructInit should be done I think.

Issue not fixed with CubeMX 4.26.0 and FW_F4 V1.21.0.
