Exiting Core Standby Mode using WKUP[4] on S32k312

saranshgoel — Tue, 17 Sep 2024 11:21:48 GMT

I am using the S32k312 board. I am currently able to wakeup the board from STANDBY mode when the GPIO PTA13 is configured as WKUP[4]. I am also able to wakeup the board from CORE-STANDBY mode when I configure the same pin as EIRQ[21].

I am not able to wakeup the board from CORE_STANDBY mode using WKUP[4]. I want to wake it up using the WKUP[4] as I also using the same pin to wake it up from STANDBY Mode. I have taken care of all the peripherals that have to be kept running while in CORE_STANDBY mode.

Can you please help me with this issue ?

Best Regards,

Hi @saranshgoel,

I have just been testing it, and I see the WPKU interrupt (nofitication) works when the core is in CORE_STANDBY (WFI).

Please share your project.

Daniel

Hi @danielmartynek ,

Thank you for your reply. I have figured out the issue. There was a mistake in the interrupt configurations. It works on my end too now.

Best regards,
