Hello @Baris ,
Some possible causes of the problem you are encountering could be related in deed to the configuration or to the application logic. Therefore, please find my input below:
- I would suggest you to try testing one of the already provided Can examples on the S32K3x4-Q172 board that you have. You could start with the s32k3xx_can_transmit_ebt and s32k3xx_can_receive_s32ct applications, and configure them for the S32K344-Q172 processor, as described in the <modelName>_example_readme.html file associated to the model. You could find these applications under the S32K3_Examples folder.
- When you configure additional instances of a component, besides the settings inside the component, you also need to make sure that the pins, clocks and interrupts are also enabled. I can see from the attached image that the pins were already routed according to your hardware, however please check also the Clocks tool (FlexCAN_4 must be enabled), and make sure that inside the Platform component, under the Interrupt Controller and Generic Interrupt Settings tabs, the FlexCAN4 interrupts that you would like to use are properly configured (enabled, a priority assigned to them, and a handler associated).
- For an example on how FlexCAN4 is configured, you can check the default configuration we provide for the S32K344-Q257 hardware part, since for that processor we enable two CAN instances.
Hope this helps,
Irina
