你好，
我有開個專案MCU選用的是STM32F091CBTx 包含CANBUS的應用，
直接下載到在NUCLEO64(STM32F091RC)的時候，CAN_TX (PA12)是可以發出CAN的訊息出來

可是當我把同一個專案直接下載到STM32F091CBTx應用板上的時候，CAN_TX (PA12)發出CAN的訊息卻是不正確的
請問一下，這是什麼原因

程式碼如下
/* CAN init function */
void MX_CAN_Init(void)
{
  CAN_FilterConfTypeDef  sFilterConfig;
  hcan.Instance = CAN;
  hcan.Init.Prescaler = 3;
  hcan.Init.Mode = CAN_MODE_NORMAL;
  hcan.Init.SJW = CAN_SJW_1TQ;
  hcan.Init.BS1 = CAN_BS1_10TQ;
  hcan.Init.BS2 = CAN_BS2_4TQ;
  hcan.Init.TTCM = DISABLE;
  hcan.Init.ABOM = ENABLE;
  hcan.Init.AWUM = DISABLE;
  hcan.Init.NART = DISABLE;
  hcan.Init.RFLM = DISABLE;
  hcan.Init.TXFP = DISABLE;
  if (HAL_CAN_Init(&hcan) != HAL_OK)
  {
_Error_Handler(__FILE__, __LINE__);
  }

sFilterConfig.FilterNumber = 0;
sFilterConfig.FilterMode = CAN_FILTERMODE_IDMASK;
sFilterConfig.FilterScale = CAN_FILTERSCALE_32BIT;

sFilterConfig.FilterIdHigh       = 0x0000;
