hello

NXP Enginer！

当我配置 S32k31x 芯片时，我对 Can_43_Flexcan 有一些疑问。

I use S32DS vesion 3.6.1，RTD vesion 4.0.0.202407242201。

I want to use interrupt function Recive the CAN message, but I don't find the "callback" function "Can_43_FLEXCAN" anywhere .Result Hardware Accpt the CAN message Software can,t Respond immediately.
I Find the isr(CAN0_ORED_0_31_MB_IRQHandler) -> Can_43_FLEXCAN_CommonIrqCallback, Can_43_FLEXCAN_CommonIrqCallback can,t callback my code.

Hello Julián_AragónM

Thank you for taking the time to pay attention to my question despite your busy schedule.

I find the new way from the "Can_Example_S32K344" .It's Block the "CanIf.c" file and Rewrtie the "CanIf_Txconfigrmation" function in the main.

The new way and you intrudce way Differences.

Best regards,
