TMS320F28379D: LAUNCHXL-F28379D

Kishor, 

If you put a break point here, does it continuously stop at the break point if you keep hitting run? From the description, I am wondering if the MCU is continuously resetting.

No, it does not stop at this breakpoint .

Kindly Resolve the earlier mentioned issues and revert back as soon as possible . 

Kindly resolve the above mentioned issues and provide the details and revert as soon as possible.

Hello Kishor, 

Which CANOpen Stack are you using? As Launchxl F28379D natively does not support CANOpen.

Hello Kishor, 

Have you resolved the CAN issue? 

I am implementing basic SDO,PDO,NMT functionalities . I am specifying indexes, subindexes and everything related to  Motor Drive in code only hence not using CANOpen stack or any object dictionary . I have to implement CANopen DS402 on motor drive for specific indices. The main concern is card is transmitting CAN data even on receiving acknowledgement from  motor drive and even on removing all interrupts , conditions it transmits data continously and for implemeting CANOpen we need to send various different packets but not continously. Is it a bug or any register condition, interrupt condition  is getting triggered or provide clarification on this 

No I have not resolved the CAN issue and I am facing same issue as mentioned earlier. Kindly resolve the above mentioned issues and provide the details and revert as soon as possible.

Hi Kishore, 

What i think the issue is that the Launchxl F28379D works on a traditional CAN BUS transmission trend because as i said, F28379D does not natively support CANOpen techniques. Hence it continuously broadcasts a message like any normal CAN device would work. I think you should go through the CANOpen specifications once and use an external stack with the development board. I dont think we can transmit and receive PDO's and SDO's using CANOpen Strategies. It will work as a normal CAN broadcasting device without CANOpen Stacks. 

I think TI suggests the SIMMA SOFTWARE stacks for CANOpen, I personally have worked with the stack and it works.  

I hope this helps.

Ok I will try SIMMA SOFTWARE stacks for CANOpen .

I have resolved the retransmit issue with setting of DAR Register but the issue is packet is transmitted only after coming out of main function. Also if I have to send multiple SDO,PDO packets then on CRO data is reflecting only after coming out of main loop . Also how to observe various packets and their acknowledgements if packet is not sent after function call when dealing with various indices. Kindly tell how to resolve this issue and why this arises.

Does PDO send request and wait for response from other CAN nodes? Did you run canOpen protocol or stack on other CAN node, so they know how to response the PDO request?
