S32k146 wake up from VLPS, program could not work continue but reset

my project is based on MCAL 4.4 RTD 1.0.0 of S32k146 with FreeRTOS, before I try to sleep, I deinit all the modules  and then use Mcu_SetMode(McuModeSettingConf_VLPS) to make mcu sleep.

But when I wake up the MCU with PortB0(GPIO), the program does not run continue but reset!

I do not know where the configuration is wrong so that the MCU could not work as expect.

Could you please help me?

I found the reset reason, not the software but the hardware does. Thanks for you attention!

Thanks for your reply! I found the reset reason that the power circuit is not strong enough and makes the mcu reset when the mcu wake up form VLPS, so our hardware engineer is working on that. If there is any other help, I will make another post.

Thank you so much!
