S32K118_PWR Mode_switch_VLPSA_Abort Issue

Kurubara — Fri, 03 Apr 2026 15:14:02 GMT

Hi Team,

Im facing Issue Like When im Switching from the VLPR to VLPs Power Mode Im Not able to Switch the Sleep State to DeepSleep State Due to VLPSA Bit Was Set 1 As Information Mention In the S32K1XX Micro Reference Manual

Very Low Power Stop Aborted
When set, this read-only status bit indicates an interrupt occurred during the previous stop mode entry
sequence, preventing the system from entering that mode. This field is cleared by reset or by hardware at
the beginning of any stop mode entry sequence and is set if the sequence was aborted.
NOTE: This bit will not get set if STOP1/STOP2 get aborted.
0 The previous stop mode entry was successful.
1 The previous stop mode entry was aborted

As Mentioned Above State Was Setting How Could I Identify the Where Exactly The Status Read from the Interrupt.

Could Please the Below Attached Snippet

Hi @Kurubara,

Please disable all peripherals that are not used in VLPS mode.
For example, set the FlexCAN module to Module Disable mode.
Next, turn off all source clocks except SIRC and LPO.
Only after completing these steps should the system enter VLPS.

BR, Daniel

The VLPSA flag can be triggered when one of the peripherals, such as FlexCAN, fails to acknowledge the transition to VLPS mode.

It also appears that you are using very old drivers, likely the legacy SDK drivers, which are no longer supported. I strongly recommend migrating to the latest RTD drivers.

To debug this issue, open POWER_SYS_SetMode() and locate the WFI instruction in the corresponding sub‑function. Set a breakpoint at that point. When the core halts on the WFI, inspect all relevant clock and peripheral registers.

Regards,

Daniel

Hi danielmartynak,
thank u for Quick Response, For S32K118, RFM‑quality software support is provided by NXP Real‑Time Drivers (RTD) v3.0.0. This release includes full quality and safety packages and is the recommended and supported solution for production‑grade applications, including correct VLPS handling. Legacy S32SDK drivers are no longer supported for RFM use. which RTD Version I Need to Use For RFM Quality.

danielmartynek — Wed, 08 Apr 2026 07:44:42 GMT

Hi @Kurubara,

You can use the latest S32K1_S32M24X Real Time Drivers AUTOSAR R21-11 Version 3.0.0 QLP06.

Hi @Daniel,
currently I'm Using SDK2.2 Version for S32K118 RFM there is not Exact RTD version We are using, Its only Flex CAN or Any Other peripherals also. Can i know the List of peripherals

HI @Kurubara,

The SDK is a legacy SW that is no longer supported.

Please use RTD.

You need to have compatible S32DS IDE.
