S32K344 - Wake up on can message

[RBSamuel]

Hello everyone!

I need to create a code for the S32K344 microcontroller that should wake the MCU up when receive a specific can message. Is there any example or tip to implement this?

I saw on the following topic that I can't use the FlexCAN module directly.

Then I configured the CAN0 TX/RX and also set the RX to be WKUP, but nothing happens after MCU enters in standby.

For this specific wkpu, I'm trying to use the wkpu module for the hardware interrupt 19, according to the S32K3xx_IOMUX.xlsx.


Thank you.

Hi @RBSamuel,

You can use the following application note as base, which showcases various wakeup use cases, including FlexCAN: S32K3 Low Power Management AN and demos - NXP Community
