IWR6843: TX issue while transmitting data over CAN

Part Number: IWR6843
Other Parts Discussed in Thread: AWR6843AOP

Tool/software:

Hi,

I have enabled can transmission over IWR6843 MCU, with the help of object_data_over_can example from the radar_toolbox_1_10_00_13. I am using PEAK CAN Analyzer to look into the data being transmitted from the Radar. I can see (in PCAN View) the data being transmitted over CAN, but when I try to transmit a frame over the same CAN Bus, the transmission halts and I need to reset the MCU to restart the communication again. [NOTE: Data is always received from the TI Radar side, the issue is surfaced if we try to transmit anything]

I put some debug statements in the MCANAppCallback() function in the event CANFD_Reason_RX and was able to narrow down that all the instructions above the CANFD_getData() function call is being executed. CANFD_getData() is an API exposed by the TI SDK, which why I am stuck about what could be the possible reasons it is failing.

If anyone can clarify the issues that can occur, and what else I should consider in my testing.

Thanks & Regards,

Prishat
