I am using the OM13094 (LPCXpresso54618 CAN-FD kit), which provides two can modules CAN1 and CAN0.
I also use the provided SDK.
I try to send a frame from CAN0 to CAN1. The frame is correctly received but CAN1 stores the frame in the wrong memory section (at MSG_RAM_BASE0+RX_FIFO1_OFS). In particular, it stores the frame as if the base address of the Message RAM used for CAN1 was the one used for CAN0.
I attach here an excerpt of the code:
#define MSG_RAM_BASE0 0x20010000U //Base address of the Message Ram for CAN0
#define TX_BUFFER_OFS 0x00U
#define RX_FIFO1_OFS 0x20U
#define MSG_RAM_BASE1 0x20010050U //Base address of the Message Ram for CAN1
//Set Base Addresses
MCAN_SetMsgRAMBase(CAN0, MSG_RAM_BASE0);
MCAN_SetMsgRAMBase(CAN1, MSG_RAM_BASE1);
/* RX fifo1 config for CAN1*/
rxFifo1.address = RX_FIFO1_OFS;
rxFifo1.elementSize = 1U;
rxFifo1.watermark = 0;
rxFifo1.opmode = kMCAN_FifoBlocking;
rxFifo1.datafieldSize = kMCAN_8ByteDatafield;
MCAN_SetRxFifo0Config(CAN1, &rxFifo1);
/* TX buffer config for CAN0*/
txBuffer.address = TX_BUFFER_OFS;
txBuffer.dedicatedSize = 1U;
txBuffer.fqSize = 0;
txBuffer.datafieldSize = kMCAN_8ByteDatafield;
MCAN_SetTxBufferConfig(CAN0, &txBuffer);
The frame received by CAN1 is stored at address 0x20010020U (MSG_RAM_BASE0 + RX_FIFO1_OFS) instead of at address 0x20010070U (MSG_RAM_BASE1 + RX_FIFO1_OFS).
Can someone provide any help about this?
