Hi,

We are using S12ZVCA for my project. We have a issue in CAN1_SendFrameExt().

bLength = 1;
pCAN_Frame_Tx = bCAN_Frame_Tx;
for(i=100;i<200;i++)
{
   dwCAN_ID = i;
   *pCAN_Frame_Tx = i-100;
   while((CAN0TFLG & 0x07U) == 0U);
   CAN1_SendFrameExt(dwCAN_ID, DATA_FRAME, bLength, bCAN_Frame_Tx);
}

It is loss the 3rd message.

OUTPUT:
00 64 00
00 65 01 (loss 00 66 02)
00 67 03
00 68 04
00 69 05

Hi,

I resolve the issue.

Click the Advanced and change the Clock source from Auto select to MSCAN0ExtClk in Processor Expert.

Best Regards,
