I can't return the tasks when wake up from VLPS in freertos

Hello, everyone.

I'm jinwon.

I'm using the following environment.

 S32K144,

 Compiler : IAR 8.30.1

 SDK :  3.0.0 RTM SDK.

 FreeRTOS v10.0.1

I switched to VLPS mode with POWER_SYS_SetMode api and wake up to RUN mode with GPIO interrupt.

Interrupt is well work, but I can not return to run Tasks.

void vApplicationIdleHook( void )
{

       // Check sleep condition

      if( POWER_STATUS_SLEEP ) {
         power_mode = POWER_SYS_GetCurrentMode();
         if( power_mode != POWER_MANAGER_VLPS ) {

                 // Change FlexCAN mode to disable mode

               FLEXCAN_DRV_Init(AMTEL_UDSCAN_INSTANCE, &canCom0_State, &canCom0_InitConfigDisable /*&canCom0_InitConfigFreeze*/ );

               // Setting GPIO interrupt

               INT_SYS_InstallHandler( PORTB_IRQn, &ISR_WakeUp_CAN_RX_PIN, (isr_t *)0 );
               PINS_DRV_SetPinIntSel( PORTB, 4U, PORT_INT_FALLING_EDGE );
               INT_SYS_EnableIRQ( PORTB_IRQn );

               status = POWER_SYS_SetMode( CONF_POWER_MANAGER_VLPS, POWER_MANAGER_POLICY_FORCIBLE );
               if( status == STATUS_SUCCESS ) {

                }

         }

      }

      // After entry VLPS mode, I can never reach here.

}

void ISR_WakeUp_CAN_RX_PIN(void)
{
      uint32_t CanRX_pin = PINS_DRV_GetPortIntFlag(PORTB) & (1 << 4U);

      if(CanRX_pin != 0)
      {
         PINS_DRV_ClearPinIntFlagCmd(PORTB, 4U);

         // I checked that this code reached here.
         status = POWER_SYS_SetMode( CONF_POWER_MANAGER_RUN, POWER_MANAGER_POLICY_FORCIBLE );
         if( status == STATUS_SUCCESS ) {

               // It's not reach here.

               // Return value is STATUS_TIMEOUT
          }

            INT_SYS_DisableIRQ(PORTB_IRQn);

             FLEXCAN_DRV_Init(AMTEL_UDSCAN_INSTANCE, &canCom0_State, &canCom0_InitConfigNormal);

              // After here, I can't run main task.
      }

}

How I can work more? Could you help me, please ?

Thank you, Daniel.

Yes, in your opinion, my colleague has created a ticket on NXP support and is in the process of making a case.

If the issue is resolved, I will add comment .

Hello Jinwon,

Could you please share the whole project or a test code at least so that we could test it.

If you don't want to share it here, you can create a ticket.

How to submit a new question for NXP Support 

Thanks,

Daniel
