STM32 MCUs Embedded software

Hi, I try to communication with two stm32f4 via CAN bus. the first board (which transmit the message) as can1 and the second (which receive the message) as can2. I'm using the new HAL_CAN function.

In polling mode, HAL_CAN_AddTxMessage() returns HAL_OK, but HAL_CAN_GetRxMessage() returns HAL_CAN_ERROR_PARAM. In interrupt mode, the function HAL_CAN_RxFifo0MsgPendingCallback() never has been called (CAN1_RX0_IRQHandler not been called). Also HAL...
