CAN Example on S32K14W-Q064 rerefence board

Hi,

I'm testing CAN communication on S32K14W-Q064 reference board. I'm using S32DS version 3.6.3 and AUTOSAR R21-11 RTD 3.0.0 recommended by here.

I'm trying to check some examples like 'CAN_example_S32K144W' and 'FlexCAN_Ip_example_S32K144W' but it doesn't work.

Could you give me some information like additional configurations or test codes? Thanks in advance.

Hi@vincent841

the demo "FlexCAN_Ip_example_S32K144W" work in flexcan loop-back mode, you need to do some modification

1.change flexcan0 work mode to normal,

2.add port for flexcan0

@Senlent thanks for your reply. I have one more question.

I found UJA1169TK(CAN0) and TJA1145(CAN1) as CAN tranceiver on the reference board(S32K14W-Q064).

Do these devices require any additional configuration for CAN communication? If so, could you share any relevant modules or example code?

Thanks in advnace.

Hi@vincent841

The UJA116x's CAN features are enabled by default, so you don't need to configure them to evaluate CAN feature.

The TJA1145 requires configuration, but I don't have driver example code for this transceiver.

If you have questions related to the UJA116x or JTA1145, please create a new topic.
