Problem with timer and input capture, timer does not run

Does anyone have experience with getting the timer to run with input capture, I am unable to make the input capture function.

I have a working system with STM32F03 (M0) devices initialization generated by CubeMX. Now I am testing an identical system with STM32G07 instead also initialization from CubeMX.

Same setup of timers but I am unable to make input capture work.

I am using TIM15 and PA2 input.

What I need is the timer to interrupt on both edges when input changes and I want to read out the time between edges. (Again functionallity was fine in STM32F03).

I configure counter mode as UP.

Prescale 10 and no internal clock division

Repetiotion counter is 0 and auto reload is disabled.

Polarity selection as both edges.

IC selection direct

No input filter (0)

To me it seems that the timer is not running, I can see from registers that edge signal is triggered and also I get an interrupt. But the timer value is always 0.

 htim15.Instance = TIM15;

 htim15.Init.Prescaler = 10;

 htim15.Init.CounterMode = TIM_COUNTERMODE_UP;

 htim15.Init.Period = 0;

 htim15.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;

 htim15.Init.RepetitionCounter = 0;

 htim15.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE;

 if (HAL_TIM_Base_Init(&htim15) != HAL_OK)

 {

  Error_Handler();

 }

 sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNAL;

 if (HAL_TIM_ConfigClockSource(&htim15, &sClockSourceConfig) != HAL_OK)

 {

  Error_Handler();

 }

 if (HAL_TIM_IC_Init(&htim15) != HAL_OK)

 {

  Error_Handler();

 }

 sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;

 sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;

 if (HAL_TIMEx_MasterConfigSynchronization(&htim15, &sMasterConfig) != HAL_OK)

 {

  Error_Handler();

 }

 sConfigIC.ICPolarity = TIM_INPUTCHANNELPOLARITY_BOTHEDGE;

 sConfigIC.ICSelection = TIM_ICSELECTION_DIRECTTI;

 sConfigIC.ICPrescaler = TIM_ICPSC_DIV1;

 sConfigIC.ICFilter = 0;

 if (HAL_TIM_IC_ConfigChannel(&htim15, &sConfigIC, TIM_CHANNEL_1) != HAL_OK)

 {

  Error_Handler();

 }

And in MSP i have:

  __HAL_RCC_TIM15_CLK_ENABLE();

  __HAL_RCC_GPIOA_CLK_ENABLE();

  /**TIM15 GPIO Configuration   

  PA2   ------> TIM15_CH1

  PA3   ------> TIM15_CH2 

  */

  GPIO_InitStruct.Pin = GPIO_PIN_2|GPIO_PIN_3;

  GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;

  GPIO_InitStruct.Pull = GPIO_NOPULL;

  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;

  GPIO_InitStruct.Alternate = GPIO_AF5_TIM15;

  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  /* TIM15 interrupt Init */

  HAL_NVIC_SetPriority(TIM15_IRQn, 0, 0);

  HAL_NVIC_EnableIRQ(TIM15_IRQn);

Anyone able to spot why the timer does not seem to run???

Please help :)
