CCS/AWR1642BOOST: Problems to use CAN

JuiYang Chi
Intellectual 860 points
Part Number: AWR1642BOOST
Other Parts Discussed in Thread: MMWAVE-SDK

Tool/software: Code Composer Studio

I have removed resistors (R4, R6, R28, R63) and shorted-circuited R11, R12. And use C:\ti\mmwave_sdk_01_01_00_02\packages\ti\drivers\can\
But I can't receive the data from AWR1642BOOST.
Are there any methods or tests that can let me know the CAN-bus runs successfully.

I'm worried about the welding error.

    Hello Juiyang,

    Below are the CAN ECO to be done on the AWR1642BOOST for the CAN communication to work.

    The CAN lines are brought out on the J3 connector of the AWR1642BOOST.

    If you are trying the CAN-FD application in the MMWAVE-SDK, you will need to configure the nominal bitrate to 1MBps and Data bitrate to 5MBps. This is the configuration the device is configured to send out the CAN messages.

    What  external CAN-FD analyser are you using ? You will need to set the CAN analyser to the above mentioned baudrates to receive and send data successfully.

    Thanks,

    Raghu

    Hello Raghu,

    According to the above figure, it just say R4, R6, R11 and R12. How about R28 and R63?

    And I use the CAN_test ,not CAN-FD. So I set the BitRate 1MHZ.
    Is it okay? I use the code from C:\ti\mmwave_sdk_01_01_00_02\packages\ti\drivers\can\

    I use MCP2515 to analysis the data to computer from CAN. Because I want to transmit code for other device.

    Because I use heat gun to remove R4, R6, R28 and R63, I worry hurt other component.
    Is there a other way to test CAN?

    Thanks,

    JuiYang

    Hello Juiyang,

    You are looking to get the DCAN interface working on the AWR1642BOOST. The DCAN connector would be available on the MMWAVE-DEVPACK .

    There are couple of ECO to be done on the MMWAVE-DEVPACK for external DCAN communication to work .

    The DCAN connectors are brought out on the J2 connector of the MMWAVE-DEVPACK. 

    With these modification and the CAN analyzer connected to the J2 of the MMWAVE-DEVPACK, your CAN communication should work with the CAN_test application in the MMWAVE-SDK.

    Thanks,
