目前CAN波特路设置为125k，用200米的线进行通讯时出现CAN_FLAG_TEC_REC_WARN这个错误，有人知道怎么回事吗？

目前在调试HC32F460时会卡在如下代码：在while(CAN_GetStatus(CAN_UNIT,CAN_FLAG_STB_TX)==RESET){}，哪位大佬可以指点一下吗？staticvoidCanTx(void){uint8_ti;staticuint8_tu8Data;for(i=0U;i<CAN_TX_DATA_SIZE;i++){m_stcTx1.au8Data=u8Data++;m_stcTx2.au8Data=u8Data++;m_stcTx3.au8Data=u8Data++;}/*FramewithCAN_ID1*/m_stcTx1.u32Ctrl=0x0UL;m_stcTx1.u32ID=CAN_TX_ID1;m_stcTx1.IDE=CAN_TX_ID1_IDE;m_stcTx1.DLC=CAN_TX_DLC;(void)CAN_FillTxFrame(CAN_UNIT,CAN_TX_BUF_PTB,&m_stcTx1);/*StartPTBTX*/CAN_StartTx(CAN_UNIT,CAN_TX_REQ_PTB);/*Checktransmissionend.*/while(CAN_GetStatus(CAN_UNIT,CAN_FLAG_PTB_TX)==RESET){}CAN_ClearStatus(CAN_UNIT,CAN_FLAG_PTB_TX);/*FramewithCAN_ID2*/m_stcTx2.u32Ctrl=0x0UL;m_stcTx2.u32ID=CAN_TX_ID2;m_stcTx2.IDE=CAN_TX_ID2_IDE;m_stcTx2.DLC=CAN_TX_DLC;(void)CAN_FillTxFrame(CAN_UNIT,CAN_TX_BUF_STB,&m_stcTx2);/*FramewithCAN_ID3*/m_stcTx3.u32Ctrl=0x0UL;m_stcTx3.u32ID=CAN_TX_ID3;m_stcTx3.IDE=CAN_TX_ID3_IDE;m_stcTx3.DLC=CAN_TX_DLC;(void)CAN_FillTxFrame(CAN_UNIT,CAN_TX_BUF_STB,&m_stcTx3);/*StartSTBTX*/CAN_StartTx(CAN_UNIT,CAN_TX_REQ_STB_ALL);/*Checktransmissionend.*/while(CAN_GetStatus(CAN_UNIT,CAN_FLAG_STB_TX)==RESET){}CAN_ClearStatus(CAN_UNIT,CAN_FLAG_STB_TX);}

我在调试HC32F460的CAN通讯时发现如果同时收到了两帧数据，第二帧数据会保存下来，导致下面接收的数据是上一帧的数据，然后后面的接收都错位了，中断里也清标志位了，有人指导一下吗？我的初始化及中断接收处理如下：[code]staticvoidCanInitConfig(uint16_tCAN_Baud_Rate){stc_can_init_config_tstcCanInitCfg;stc_can_filter_tastcFilters[CAN_FILTERS_COUNT]=\{{0x00000000ul,0x111ul,CanFilterSel1,CanAllFrames}};//

如图，是我从GD32F103数据手册中截取出来的，请问该模式下VDD是掉电的吗？那么当他被唤醒时VDD是自动上电吗？请大神讲解一下！多谢大佬！
