1. 在CPU1中通讯没有问题，但换到CPU2中，就通讯不了。
2 .在CPU1中通讯时，按以下配置，可正常通讯：
GPIO_SetupPinMux(62, GPIO_MUX_CPU1, 6);
GPIO_SetupPinMux(63, GPIO_MUX_CPU1, 6);
GPIO_SetupPinOptions(62, GPIO_INPUT, GPIO_ASYNC);
GPIO_SetupPinOptions(63, GPIO_OUTPUT, GPIO_PUSHPULL);
CANInit(CANA_BASE);
CANClkSourceSelect(CANA_BASE, 0);
CANBitRateSet(CANA_BASE, 200000000, 500000);
CANEnable(CANA_BASE);
收/发数组定义:
*(unsigned int *)ucTXMsgData = 0;
sTXCANMessage.ui32MsgID = 0x500A01; // CAN message ID - use 1
sTXCANMessage.ui32MsgIDMask = 0; // no mask needed for TX
sTXCANMessage.ui32Flags = MSG_OBJ_TX_INT_ENABLE; // enable interrupt on TX
sTXCANMessage.ui32MsgLen = sizeof(ucTXMsgData); // size of message is 4
sTXCANMessage.pucMsgData = ucTXMsgData; // ptr to message content
*(unsigned int *)ucRXMsgData = 0;
sRXCANMessage.ui32MsgID = 0x500B01; // CAN message ID - use 1
sRXCANMessage.ui32MsgIDMask = 0; // no mask needed for TX
sRXCANMessage.ui32Flags = MSG_OBJ_NO_FLAGS;
sRXCANMessage.ui32MsgLen = sizeof(ucRXMsgData); // size of message is 4
sRXCANMessage.pucMsgData = ucRXMsgData; // ptr to message content
3. 移动到CPU2时，CAN通讯通讯不了，程序如下：
在CPU1中定义：
GPIO_SetupPinMux(62, GPIO_MUX_CPU2,6);
GPIO_SetupPinMux(63, GPIO_MUX_CPU2,6);
CANInit(CANA_BASE);
CANClkSourceSelect(CANA_BASE, 0);
CANBitRateSet(CANA_BASE, 200000000, 500000);
CANEnable(CANA_BASE);
在CPU2中定义收/发通讯数组，不能通讯；或者将
CANInit(CANA_BASE);
CANClkSourceSelect(CANA_BASE, 0);
CANBitRateSet(CANA_BASE, 200000000, 500000);
CANEnable(CANA_BASE);
放到CPU2中，也不能通讯。
请教大家在CPU2中分配CAN通讯,除了分配GPIO口设置，还需要那些配置？
