Hello Champs,

How to set the mask bit (eg: 0x400~0x41f) of a certain segment of the received message ID in MCUSW  autosar?

Thanks.

    Hello Shine,

    Can you elaborate on the driver you are referring to inside of MCUSW? You mentioned the "Received Message ID", it sounds like a communication protocol. Also, can you add which SDK version you are using?

    Thanks,

    Erick

    Hi Erick,

    Thanks for your quick reply. 

    Customer is referring to the CAN driver, which needs to filter and receive the CAN ID of a certain network segment (such as 0X400~0X47F), and the SDK package is 8.03 or 8.04 (tda4vl).

    Thanks.

    Hi Shine

    So essentially you are looking to add a range filter for all IDs from 0x400 to 0x47F?

    Currently the MCAL CAN driver has the configuration where if for standard CAN IDs you set CanHandleType == CAN_FULL (in Can_Cfg.c) will in turn the SFT to 0x0 (Range Filter from SFID1 to SFID2) and SFID2 to 0x7FF (Max for standard IDs).

    If you modify the Can_Cfg.c to update the CanHwFilterCode = 0x400 then this will modify the SFID1 to 0x400 and hence you should be able to setup a range filter from 0x400 to 0x7FF.

    Now in case this doesn't work for you and leads to unintended message reception, then we need to make a driver modification to make SFID2 as 0x47F.

    Regards

    Hi Karan,

    Thanks for your support. 

    Following your suggestion, customer modified the code as follows:


    But still unable to receive any ID in the 0x400~0x47F network segment.

    The MCANSS_RX_BUFFER_ELEM_ID_MASK received at the bottom layer in Mcan.c is 0x1FFFF480U, and it still cannot be received.

    Thanks.

    Hi Karan,

    Customer has resolved the issue by setting CanHandleType =1(Basic) to 1.

    Thanks for your support.
