IWR6843ISK: CANFD does not work in IWR6843ISK + IWR6843-Carrier Eval-Board using canfd driver demo test

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843

Hi,

I'm trying to get CANFD to work on IWR6843ISK and IWR6843-Carrier Board. I have run the example code for CANFD driver "C:\ti\mmwave_sdk_03_03_00_03\packages\ti\drivers\canfd\test\xwr68xx\xwr68xx_canfd_mss.xe4f", however I received no data from the MMWAVEBOOST.

I did look into the schematics of IWR6843_ISK_Schematic_Assembly_BOM and saw that there is no CANFD being used. So my questions are:

1) Is it possible to run CANFD example on the IWR6843ISK + IWR6843-Carrier ?

2) As I see that man can used different pins for CAN_FD e.g D13,F14... for CANFD_RX and E14, H14... for CANFD_TX. Which TX/RX-Pins do I have to use for CANFD communication when using IWR6843ISK + IWR6843-CArrier Board ?

3) Which MUX-configuration on IWR6843-Carrier do I have to set to CAN_FD communication to work ?

Thanks very much.

Bien

    Hi Bien,

    Responses:

    1) Yes.  You have already found the SDK's driver test code for IWR6843.  It is probably easiest to run in the CCS debugger.  You will see that it waits for a test number.  You can stop the code and set the variable to the desired test number and restart it.

    2/3). You will find the proper pinmux is setup in the test code.  

    For some of the tests, external connections must be made. You can find the CANFD test procedure in this thread:

    https://e2e.ti.com/support/sensors/f/1023/t/879653

    If external hardware is connected to the EVM, you need to make sure that the external device is using the same message IDs as are configured in the test code (or modify the test code). Otherwise you will not receive messages.
