I cannot make the CAN TX interrupt work (CAN RX int does work, though):

Using: stm32l476 on the ST eval board, I set the CAN INT as follows:

if (HAL_CAN_ActivateNotification(&CanHandle, CAN_IER_TMEIE | CAN_IER_FMPIE0 | CAN_IER_ERRIE |

CAN_IER_EPVIE | CAN_IER_BOFIE) != HAL_OK)

{

/* Notification Error */

Error_Handler();

}

Any idea?

Does it end up in the Error_Handler()?

Does it end up in the Default_Handler()?

Do you have body code for an CAN1_TX_IRQHandler?

It end up in no handler, no exception. I do have a body code for CAN1_TX_IRQHandler()

NVIC?

/* NVIC configuration for CAN1 Transmission interrupt */

HAL_NVIC_SetPriority(CAN1_TX_IRQn, 1, 0);

HAL_NVIC_EnableIRQ(CAN1_TX_IRQn);
