hello Infineon Expert:
the development environment is, ADS V1.8, TC367 TriBoard (EvtBoard with TFT LCD).
CAN Node 0 rxMode is initialized as mixed mode of standard filter and FIFO 1 code.
filter #3 is initialized as 'IfxCan_FilterType_range' type. range is [0x400, 0x47F]
other Filters (0~2 and 4~10) is initialized as 'IfxCan_FilterType_classic'
The transmission of CAN messages works well. The reception of also works well except the ID in [0x400, 0x47F]
If I sent a message ID like 0x415 from CanOe, the iLLD function
IfxCan_Can_getRxFifo1FillLevel(&gblCanDriver.canNode[0] return value means expected message received
In iLLD function, IfxCan_Can_readMessage() , when this line code is executed
IfxCan_Node_readData(rxBufferElement, message->dataLengthCode, data);
the CPU0 runs into Instruction Error Trap.
Actually, this line code in IfxCan.c, function IfxCan_Node_readData() causes the Trap.
data[i] = destinationAddress[i];
The received Message Id is correct and in memory address , 0xF0200208, its data is CAN PDU sent from Canoe
I don't know whether the 'rxBuffersStartAddress' and 'rxFifo1StartAddress' is initialized correct or not.
Following is part of my code, the whole CAN_driver.c is also attached .
The Node initialization function is below
void Init_CanDriver_Node0()
{
uint8 i;
IfxCan_Can_Config canConfig;
IfxCan_Can_NodeConfig nodeConfig;
/*CAN0 Initialization */
IfxCan_Can_initModuleConfig(&canConfig, &MODULE_CAN0);
IfxCan_Can_initModule(&gblCanDriver.can[0], &canConfig);
/* CAN 0 Node0 initialization */
IfxCan_Can_initNodeConfig(&nodeConfig, &gblCanDriver.can[0]);
nodeConfig.nodeId = IfxCan_NodeId_0;
nodeConfig.frame.type = IfxCan_FrameType_transmitAndReceive;
nodeConfig.txConfig.dedicatedTxBuffersNumber = 32;
nodeConfig.rxConfig.rxMode = IfxCan_RxMode_sharedFifo1;
nodeConfig.rxConfig.rxFifo1Size = 32;
nodeConfig.messageRAM.txBuffersStartAddress = 0x400;
nodeConfig.filterConfig.standardListSize = 32;
nodeConfig.messageRAM.standardFilterListStartAddress = 0x00;
nodeConfig.messageRAM.rxBuffersStartAddress = 0x200;
nodeConfig.messageRAM.rxFifo1StartAddress = 0x200;
nodeConfig.messageRAM.baseAddress = (uint32)&MODULE_CAN0;
IfxCan_Can_Pins pins;
pins.rxPin = &IfxCan_RXD00B_P20_7_IN;
pins.rxPinMode = IfxPort_InputMode_pullUp;
pins.txPin = &IfxCan_TXD00_P20_8_OUT;
pins.txPinMode = IfxPort_OutputMode_pushPull;
pins.padDriver = IfxPort_PadDriver_cmosAutomotiveSpeed2;
nodeConfig.pins = &pins;
IfxCan_Can_initNode(&gblCanDriver.canNode[0], &nodeConfig);
/*initialize the rx messages and Tx messages buffer*/
for(i = 0; i < MAX_MSG_RECV_BUF_NODE0; i++)
{
IfxCan_Can_initMessage(&rxMsgBufNode0[i]);
rxMsgBufNode0[i].bufferNumber = i;
}
/*initialize the module global tx message*/
for(i = 0; i < MAX_MSG_SEND_BUF_NODE0;i++)
{
IfxCan_Can_initMessage(&txMsgBufNode0[i]);
txMsgBufNode0[i].bufferNumber = i;
}
}
HW buffer of FIFO1 is initialized as below:
void InitOsekNmRx_Node0()
{
IfxCan_Filter filter;
/*initialize the NM reception HW buffer dedicated filter */
filter.number = NM_RECV_BUF_ID; //#3 filter
filter.elementConfiguration = IfxCan_FilterElementConfiguration_storeInRxFifo1;
filter.id1 = 0x400;
filter.id2 = 0x47F;
filter.type = IfxCan_FilterType_range;
filter.rxBufferOffset = NM_RECV_BUF_ID;
IfxCan_Can_setStandardFilter(&gblCanDriver.canNode[0], &filter);
/*initialize OSEK NM reception message buffer */
rxMsgBufNode0[NM_RECV_BUF_ID].messageId = 0x400;
rxMsgBufNode0[NM_RECV_BUF_ID].readFromRxFifo1 = TRUE;
/*initialize OSEK NM transmission message buffer */
txMsgBufNode0[NM_SEND_BUF_ID].messageId = 0x419;
}
The function handling FIFO message reception is below:
uint32 OsekNmRecvMessage(int node, uint8 * pData)
{
uint32 recvId = 0;
if(0 == node)
{
/*check the HW buffer dedicated to UDS physical addressing request message ID*/
if(IfxCan_Can_getRxFifo1FillLevel(&gblCanDriver.canNode[0])>0)
{
IfxCan_Can_readMessage(&gblCanDriver.canNode[0], &rxMsgBufNode0[NM_RECV_BUF_ID], (uint32*)pData);
recvId = rxMsgBufNode0[NM_RECV_BUF_ID].messageId;
// dlc = (int)dlcCodeAndLenMappingTbl[(int)rxMsgBufNode0[NM_RECV_BUF_ID].dataLengthCode];
}
}
return recvId;
}
thanks and BR
