STM32F105RBT6 -> No interrupt from CAN2

[HitTive]

Hi, I have a problem. I can transmit data with Can2 but input data isnt generate any interrupt. I use a HAL libraries. I can see a correct input data in CAN_RDL0R and CAN_RDH0R register. CAN1 work properly.

CAN1 and CAN2 configuration code:
if (_hCANx == &hcan1) {
		CAN_FilterConfTypeDef filter;

		filter.FilterNumber = 0;
		filter.FilterMode = CAN_FILTERMODE_IDMASK;
		filter.FilterScale = CAN_FILTERSCALE_32BIT;
		filter.FilterIdHigh = 0x0000;
		filter.FilterIdLow = 0x0000;
		filter.FilterMaskIdHigh = 0x0000;
		filter.FilterMaskIdLow = 0x0000;
		filter.FilterFIFOAssignment = CAN_FILTER_FIFO0;
		filter.FilterActivation = ENABLE;
		filter.BankNumber = 0;
		HAL_CAN_ConfigFilter(&hcan1, &filter);

		HAL_CAN_Receive_IT(&hcan1, CAN_FIFO0);

		_Status |= CAN_INITIATED;

		return 0;
	} else if (_hCANx == &hcan2) {
		CAN_FilterConfTypeDef filter;

		filter.FilterNumber = 14;
		filter.FilterMode = CAN_FILTERMODE_IDMASK;
		filter.FilterScale = CAN_FILTERSCALE_32BIT;
		filter.FilterIdHigh = 0x0000;
		filter.FilterIdLow = 0x0000;
		filter.FilterMaskIdHigh = 0x0000;
		filter.FilterMaskIdLow = 0x0000;
		filter.FilterFIFOAssignment = CAN_FILTER_FIFO1;
		filter.BankNumber = 14;
		filter.FilterActivation = ENABLE;
		HAL_CAN_ConfigFilter(&hcan2, &filter);

		HAL_CAN_Receive_IT(&hcan2, CAN_FIFO1);

		_Status |= CAN_INITIATED;

		return 0;
	}

and rest configuration od CAN2 is the same like CAN1 (without GPIO of course)
