How to implement S32K144 CAN Pretended Networking mode

alstlr926 — Mon, 13 Apr 2020 07:00:36 GMT

Dear supporters,

I have succeeded in implementing CAN transmission and reception through [FlexCAN_s32k144] example. And now I want to run CAN Pretended Networking mode using S32K144 EVB. However, no example file was found.
I have read [53.5.5 Receive process under Pretended Networking Mode] of Reference Manual, but there are some parts that I don't understand, so I want to use reference materials.

Please let me know if you have a reference or an example file for the Pretended Networking mode of S32K144.
If not, please give me an easy-to-access guide.

Thank you,

Minsik.

Hello alstlr926@naver.com,

There is this non-SDK example https://community.nxp.com/docs/DOC-346305

If you are using the SDK FlexCAN driver, the Processor Expert allows you to configure the PE mode.

But we don't have any SDK example yet.

Also, there is this example for MPC5748

Example MPC5748G PretendedNetworkingCAN S32DS_1.0

Regards,

Daniel

Hello, Daniel

Thank you for helping me. I have one more question. In the example, the MCU itself switches to STOP mode, and a CAN message is used to wake-up it, but is there a way to wake-up it while allowing only the CAN module, not the MCU, to switch to STOP mode?
* Only CAN module will switch to STOP mode and hope to continue MCU activation mode.

Minsik

Hello Minsik,

Unfortunately, the FlexCAN module enters its Stop mode only when a system stop mode is requested at the chip level.

Daniel
