AWR1843: About DCAN Issue

Part Number: AWR1843

Hi SIr 

We used AWR1843 with latest SDK for development and there are some issues

1. We used CAN bus for data transmission and got data lost. And we only run MRR in AWR1843.

    Do you have any suggestion how to debug ?

2. for CAN bus throughput 

      a. will it affect the throughput  if we only run MRR or run MRR+SRR feature ? 

      b, Do we have any suitable tool or method to measure the can bus throughput  

BR

    Yimin,

    A1: You will need to check if there are any TX messages pending before sending the next packet. Please include DCANIsTxMsgPending() in your code to wait for the TX message pending.

    A2: There would not be any affect on the CAN throughput when using the MRR code . You just need to make sure you have enough time to send out the object data over the CAN interface during the interframe time. Moreover all the processing of the data is happening in the DSP which will not effect the throughput.

    Thanks,

    Raghu
