I ask you about flasing elf file on TC275

I solved it.

Is there anyone who use CAN Bus Shield on TC275 ??

You can use a standard Arduino CAN shield but this uses a Microchip standalone CAN controller that interfaced via the SPI. It is better to use the TC275's own CAN modules and add CAN transceivers on a prototyping shield. We are considering making a CAN shield for the ShieldBuddy.

Here is an example sketch for using the TC275's own CAN modules:






/*** Core 0 ***/

void setup() {
// put your setup code for core 0 here, to run once:

SerialASC.begin(9600);

CAN0_Init(250000);
CAN1_Init(250000);


/* Parameters CAN ID, Acceptance mask, data length, 11 or 29 bit ID, Message object to use */
CAN0_TxInit(0x100, 0x7FFFFFFFUL, 8, 11, 0);

CAN1_RxInit(0x100, 0x7FFFFFFFUL, 8, 11, 1);

/* Dual Test */
CAN0_TxInit(0x101, 0x7FFFFFFFUL, 8, 11, 2);
CAN1_RxInit(0x101, 0x7FFFFFFFUL, 8, 11, 3);

/* Triple Test */
CAN1_TxInit(0x102, 0x7FFFFFFFUL, 8, 11, 4);
CAN0_RxInit(0x102, 0x7FFFFFFFUL, 8, 11, 5);

SerialASC.print("Multican is Initialized\n\r");

}



void loop() {
// put your main code for core 0 here, to run repeatedly:

IfxMultican_Message msg1;
IfxMultican_Status RxStatus;

const uint32 dataLow = 0x12340000;
const uint32 dataHigh = 0x9abc0000;

uint32 errors = 0;

/* Transmit Data */
{

/* Parameters CAN ID, 32 bits low data, 32 bits high data, data length */
CAN0_SendMessage(0x100, 0x12340000, 0x9abc0000, 8); // Original
//CAN1_SendMessage(0x100, 0x12340000, 0x9abc0000, 8);

/* Dual test */
CAN0_SendMessage(0x101, 0x12340000, 0x9abc0000, 8); // Original

/* Triple Test */
CAN1_SendMessage(0x102, 0x12340000, 0x9abc0000, 8); // Original
}

/* Receiving Data */
{
/* wait until MCAN received the frame */

/* Test 1 */
/* Parameters CAN ID, address of structure to hold returned data, data length */
RxStatus = CAN1_ReceiveMessage(0x100, &msg1, 8); // Original
//RxStatus = CAN0_ReceiveMessage(0x100, &msg1, 8);

if (RxStatus != IfxMultican_Status_noError)
{
SerialASC.print("ERROR: single IfxMultican_Can_MsgObj_read Message returned ");SerialASC.print(RxStatus,HEX); SerialASC.print("\n\r");
}


/* check the received data */
if (msg1.data[0] != dataLow)
{
++errors;
}

if (msg1.data[1] != dataHigh)
{
++errors;
}

if (errors)
{
SerialASC.print("ERROR: Found (errors)");SerialASC.print(errors);SerialASC.print("\n\r");
}
else
{
SerialASC.print("OK: single test Checks passed\n\r");
}

/* Test 2 */
RxStatus = CAN1_ReceiveMessage(0x101, &msg1, 8);

if (RxStatus != IfxMultican_Status_noError)
{
SerialASC.print("ERROR: dual test IfxMultican_Can_MsgObj_read Message returned ");SerialASC.print(RxStatus,HEX); SerialASC.print("\n\r");
}

/* check the received data */

RxStatus = CAN0_ReceiveMessage(0x102, &msg1, 8);

if (RxStatus != IfxMultican_Status_noError)
{
SerialASC.print("ERROR: triple test IfxMultican_Can_MsgObj_read Message returned ");SerialASC.print(RxStatus,HEX); SerialASC.print("\n\r");
}
