S32K3x4 RTI wake

vinaykl — Wed, 04 Jun 2025 04:33:43 GMT

Hello Team,

I am using S32K3x4 Evaluation kit with S32 DS 3.4 update pack 3 and with RTD 2.0.3. I found an example from forum which uses PIT RTI to wake from StandBy mode. I had migrated it to RTD 2.0.3. But the this is it's not waking up after timeout from RTI.

Kindly let me know if anything is wrong with my configuration. Adding my project with this response.

Thanks, and regards,

Vinay

Hi Vinay,

SIRC need to be enabled in Standby mode, refer to the image in Example S32K312 STANDBY wake up using RTC DS3.5 RTD300

Hello Robin_Shen,

I have enabled SIRC in standby mode, still the board is not waking up by RTI.

Kindly let me know what else I need to change to make it work.

Thanks and regards,

There is a working S32K344_RTI_Cycl_Wkup_S32DS_3_4_RTD_LLD_2_0 example in S32K3 Low Power Management AN and demos.
If this is your new project, I would recommend you to add your own code based on S32K3 Low Power Management AN and demos RTD 4.0.0 & 5.0.0.

I tested your project and it is indeed unable to wake up. I found many differences when comparing it with S32K344_RTI_Cycl_Wkup_S32DS_3_4_RTD_LLD_2_0.
Due to the complexity of the project, I did not conduct a complete inspection. I only listed a few points that affect wake-up:

Hello Robin_shen,

I have changed all the configuration as per your guidance.

But if I tick "Last Mile Regulator Base Control Enable" my application is not even running correctly. So, I disabled and tried running it.

It is successfully entering StandBy mode but could not be able to wake from RTI.

I have migrated from S32K344_RTI_Cycl_Wkup_S32DS_3_4_RTD_LLD_2_0 to RTD 2.0.3 and changed name to the application you I previously shared to you.

Sharing latest copy of my project.

Please let me know what changes I need to be doing to make it work.

Thanks and regards,

Vinay

Please check the project I sent you separately. Then let me know the result.
If it still doesn't work, please tell me what is the SCH version of S32K3X4EVB-T172.
