MSPM0G3507: CAN frame repeated on early samples

Part Number: MSPM0G3507

Hello,

I am using the mscan single frame example on an early sample

I send the frame every second based on a timer

I made one IO toggle, timer is correct, and can functions are called every second

In the program in modified the CAN setting to CAN not FD

One time there is one frame sent, at next period 3 frames are sent

This is cyclic

Is there anything I shall do to correct those 3 frames?

/* Frame transmitted in CAN FD format. */
txMsg.fdf = 0U;//1U;

/* Write Tx Message to the Message RAM. */
DL_MCAN_writeMsgRam(MCAN0_INST, DL_MCAN_MEM_TYPE_BUF, 0U, &txMsg);
/* Add request for transmission. */
DL_MCAN_TXBufAddReq(MCAN0_INST, 0U);
//DL_GPIO_togglePins(GPIO_PORT, GPIO_TEST_PIN);

Thanks

Hi Thomas,

Which version of the SDK did you use? Did you receive CAN frames with a CAN analyzer?

Thanks,

Yuhao

I took a second PCB and there are no issues - it's maybe linked to this action, let me check - e2e.ti.com/.../4641561

Okay the non main memory modification doesn't change anything - only difference I can see is the capacitors of the crystal - let me dig that and try with more boards (it's still unsolved as I don't understand the reason)
