LP-MSPM0G3519: undeclared identifier 'CAN_UNINIT' and 'CAN_READY'

Prashant Singh Tomar
Prodigy 190 points
Part Number: LP-MSPM0G3519

Tool/software:

Hello team,

we are using MCAL : MCAL_MSPM0_00.02.04.00 package

SDK : mspm0_sdk_2_04_00_06 version

While integrating Can module, below compilation error is occured

Error:

C:/work/ACP-9.3.2_MSPM0GX51X_ticgt-4.0.0_LTS_BasicTemplate/Tresos/plugins/McalExt_TS_T47DxM1I0R0/MCAL_Delivery/mcal/Can/src/Can.c:181:41: error: use of undeclared identifier 'CAN_UNINIT

C:/work/ACP-9.3.2_MSPM0GX51X_ticgt-4.0.0_LTS_BasicTemplate/Tresos/plugins/McalExt_TS_T47DxM1I0R0/MCAL_Delivery/mcal/Can/src/Can.c:790:24: error: use of undeclared identifier 'CAN_READY'

Reason:   

Although the states CAN_UNINIT and CAN_READY are already defined in Can_GeneralTypes.h, as per the AUTOSAR standard, such states should be handled internally by the driver.

BR,

    Hi Prashant,

    Thanks for your feedback and sorry for the late response.

    As for the compile error, I tested with the CanApp example in the MCAL package, but not find this error. As you said, the CAN_UNINIT and CAN_READY is defined in Can_GeneralTypes.h, which is further included in the can.h file. If you keep these header file as same, I think this macro undeclared error should not occur.

    Could you please share more information about your problem background? Thanks.

    Best Regards,

    Pengfei

    Hi Pengfei

    If we include Can_GeneralTypes.h, we get a lot of errors related to redefinition. Please check the error log below.

    Hi Prashant,

    Sorry I may not state clearly. I did not let you to include the Can_GeneralTypes.h in your main program, actually this header file is included in Can.h file, and you could directly include Can.h in your main program.  

    You could refer to CanApp.c example in path of \mcal\examples\Can\soc\MSPM0G351x\m0plus\CanApp.c.

    Hi Pengfei Xie,

    Sorry for the late reply. What I meant to say is that, according to the AUTOSAR standard, the Can_GeneralTypes.h file should be included from the AUTOSAR Base Module, not from the vendor implementation. Therefore, the states CAN_UNINIT and CAN_READY, which are already defined in Can_GeneralTypes.h, should be referenced in either Can.h or any common header file included within the CAN driver implementation.

    BR,
