So, when I debug the code, it's waiting at WFI(). As far as wakeup is concerned, I have enabled EXTI on PF10.
This is my pre sleep function:
void PreSleepProcessing(uint32_t *ulExpectedIdleTime)
{
osTimerStop(mt_TimerInt); // TimerB0 stop
ein_EinFktInitslow(); //Stop timers
hw_SetSpeedSlow();
hw_IntSavflash(); //Disable all IRQs using HAL function
HAL_SuspendTick(); //Time base: Tim3
}
Post Sleep:
void PostSleepProcessing(uint32_t *ulExpectedIdleTime)
{
HAL_ResumeTick();
hw_IntResflash(); //Enable all IRQs
hw_SetSpeedFast();
osTimerStart(mt_TimerInt, _MTZ_50ms*50); // TimerB0 starten
ein_EinFktInitAlle(); //now activate timers
}
vPortSuppressTicksAndSleep Function's snippet from port.c file. Commented out the 2nd and 15 line and added 14th to make it compatible for tickless mode (followed this tutorial https://youtu.be/B1cUWRpXrPU). Nothing else changed in this file.
/* Restart SysTick. */
// portNVIC_SYSTICK_CTRL_REG |= portNVIC_SYSTICK_ENABLE_BIT;
/* Sleep until something happens. configPRE_SLEEP_PROCESSING() can
set its parameter to 0 to indicate that its implementation contains
its own wait for interrupt or wait for event instruction, and so wfi
should not be executed again. However, the original expected idle
time variable must remain unmodified, so a copy is taken. */
xModifiableIdleTime = xExpectedIdleTime;
configPRE_SLEEP_PROCESSING( xModifiableIdleTime );
if( xModifiableIdleTime > 0 )
{
__asm volatile( "dsb" ::: "memory" );
HAL_PWREx_EnterSTOP1Mode(PWR_STOPENTRY_WFI);
// __asm volatile( "wfi" );
__asm volatile( "isb" );
}
configPOST_SLEEP_PROCESSING( xExpectedIdleTime );
Hopefully, this much code is enough.
