SK-AM62A-LP: About CANFD transferred data with CAN tools on AM62A7

Part Number: SK-AM62A-LP
Other Parts Discussed in Thread: AM62A7, SYSCONFIG

My target currently is just completing the basic communication on AM62A7 with external CAN tools, such as Canoe or ZLG tool etc..  The circuit schematics about this module is below:

           mcan_loopback_interrupt_am62ax-sk_mcu-r5fss0-0_nortos_ti-arm-clang.zip

Now the above attached file is my basice code project,which could be run on CCS in platform Ubuntu or Windows PC. I just make some simple configurations below:

1. set MCU_CAN2_STBz low level:

2.set the CANFD Bitrate to 2Mbps, change to CAN mode:

After compiling and running the project, it shows the data result on the COM port:

So my question is that how I could get & print the CANFD data from the external CAN tools like this just by changing the loopback mode? I hopefully realize the basic function about  transferring data each other with CAN tools currently.

By the way, what's the dfference on the version of my Sysconfig tools with below:

    Hi Django, 

    Thank you for your question. 
    Could you specify the SDK version you are using currently?

    As of now, external loopback example is not a supported feature in our SDKs. 
    We have taken your input and working on it. Please allow us some time to get back to you.

    Regards,

    I downloaded the file "mcu_plus_sdk_am62ax_08_06_00_18-linux-x64-installer"from TI website. In additon, the configuration related CANFD bitrate should be check as I posted above. At last, what's the version of Sysconfig tool by which I could check the Sampling point conveniently? As you know, the 1.18.0 Sysconfig doesn't have this item in the list.

    Hi Django, 
    The image that you have shared earlier are sys-cfg settings from a different device (AM64x). The external loopback example is present in AM64x; hence you see those parameters added. As I had mentioned, we are looking into adding support for AM62A as well. Hope this clears your doubt. 

    Will update you on this as soon as possible. 

    Regards,

    I've added the part as below pic. into the k3-am62a-mcu.dtsi according to the TI web instruction.
    Now we plan to get the data from mcu_mcan1 sended by using the ZLG tools. How many simple steps should be done to modify the TI demo code base on "mcan_loopback_interrupt_am62ax-sk_mcu-r5fss0-0_nortos_ti-arm-clang"?

    Hi Django,

    As mentioned earlier, the team is looking into adding this support for AM62Ax.
    Meanwhile, you can refer to AM64x and port the external loopback example. Also, you can refer to the documentation.

    Please note that external loopback has not been tested yet on AM62Ax.
