Hi e2e, I am using the AWR6843ISK with MMWAVEICBOOST for my use-case that requires CANFD.

I want to transfer my point cloud data via CANFD. I have a working code with same functionality on AWR1843 board, I have migrated the code from AWR1843 to AWR6843.

Problem is the function "CANFD_transmitData" is returning error code of -3502 which corresponds to CANFD_EINUSE.

This is mostly because my first packet request is not being processed and hence when next packet request is sent I get this error code.

I have tried changing the switch position S1.1 on MMWAVEICBOOST which switches between CANFD and SPI.

Hi,

The above settings looks correct from the HW point of view. Can you confirm if the signal is connected to the CANFD port J1? Pin 1 is CAN1_TX and pin3 is CAN1_RX.

Also you can try the test code in SDK for CAN FD (C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\canfd\test\xwr68xx) to verify the basic CAN functionality?

1. Yes, connection is proper and connected to CANFD.
2. I have tried the test code in AWR6843, and CANFD is able to transmit the data. I m using Peak CAN for analyzing the data.

Hi,

Thanks for confirming this information! Can you please check your functional code is using the same drivers as the test example?

Thank you for your help.

Code is working now.

Problem was we were using SPI A along with CAN, once I disables SPI I m able to send data. We will be switching to SPI B in order to use both SPI and CAN.
