Not able to go to STOP1/STOP2/VLPS Modes using Power management SDKs

[KARTHKSARODE]

Hi Team 

I'm trying to go to STOP/VLPS mode using only power management SDKs but unfortunately it is not happening for STOP1/STOP2/VLPS but the same power management SDKs are able to switch mode to HSRUN , VLPR 

Right now , I'm using 2 statements from SDKs POWER_SYS_Init & POWER_SYS_SetMode 

Please let me know if I'm doing something wrong , when I tried to execute some sample code which doesnt have any SDKs , it is going to STOP mode 

But I want some referenece of Power Management SDKs

Thanks & Regards

Hi Karthik,

Have you tried the power_mode_switch_s32k144 SDK example?

It shows transitions to all the available power modes.

Which version of S32 Design Studio do you have?

Go to: File / New / S32 Project from Example

You should see it there.

This is S32DS 2.2 with SDK RTM 3.0.0:

Hi Daneil 

I could able to go to STOP1/STOP2/VLPS mode using the example code 

But help me understanding following things in that example code :

• Once it reaches STOP1/STOP2/VLPS mode , Is it automatically entering RUN mode(Clearly written in Print Statement -- PFA) ?
• 

   If it is automatically entering RUN mode , how to disable that ??

• If it is not entering RUN mode , if I configure pretended CAN network , will it recover from STOP1/STOP2/VLPS Mode if I recieve CAN message???

Best Regards

Hi Karthik,

It can also go from VLPS to VLPR if VLPR was the active mode before VLPS.

The Pretending network mode is supported in STOP1 and STOP2

Example S32K144 FlexCAN Pretended Networking STOP mode test S32DS.ARM.2.2
