Sorry, the problem is hardware.

Hello,

I succeed to send a CAN message in LoopBack mode. But when I try to communicate with an other microcontroller in Normal mode, TransmitMailbox is always equal to CANTXPENDING.

My code :

/* CAN cell init */

CAN_InitStructure.CAN_TTCM = DISABLE;

CAN_InitStructure.CAN_ABOM = DISABLE;

CAN_InitStructure.CAN_AWUM = DISABLE;

CAN_InitStructure.CAN_NART = DISABLE;

CAN_InitStructure.CAN_RFLM = DISABLE;

CAN_InitStructure.CAN_TXFP = DISABLE;

CAN_InitStructure.CAN_Mode = CAN_Mode_Normal;

CAN_InitStructure.CAN_SJW = CAN_SJW_1tq;

CAN_InitStructure.CAN_BS1 = CAN_BS1_8tq;

CAN_InitStructure.CAN_BS2 = CAN_BS2_7tq;

CAN_InitStructure.CAN_Prescaler = 1;

CAN_Init(&CAN_InitStructure);

/* transmit */

TxMessage.StdId = 0x01;

TxMessage.RTR = CAN_RTR_DATA;

TxMessage.IDE = CAN_ID_STD;

TxMessage.DLC = 2;

TxMessage.Data[0] = 0x01;

TxMessage.Data[1] = 0x00;

TransmitMailbox = CAN_Transmit(&TxMessage);

What are the other changes that I should do to pass in Normal mode?
