Other Parts Discussed in Thread: AWR1843,
We have a Radar sensor device which is developed based on AWR1843 Boost and automotive lab demo MRR.
One difference of our radar sensor and AWR1843boost is that it doesn't have a 120ohm registor for CAN bus communication.
When we add an external 120ohm resistor on the CAN interface of Radar sensor. It work fine when the Radar sensor start running the mrr demo program.
However, if the Radar sensor start running the mrr demo program without the 120ohm registor, the program will stops or crashes very soon.
During the investigation, I find that the issue seems is related with the CANFD_transmitData. Because when the program doesn't call CAN FD transfer data function, the program will not crashes.
Further, I checked the return value and the error code that are set up after the CANFD_transmitData is called. But for both conditions: with 120ohm and without 120ohm, the return value and the error code are the same.
Now I suspect the issue is caused by CAN FD driver setting, I am still investigating. Will great appreciate if you can give me any advice. I think the program should be always running properly with or without the 120ohm registor.
Thanks
