especially if nested interrupts is all working as it should. Average Current is 500~600uA when device is sleep mode when System ON mode.

Without an RTOS you can also do sleep(n milliseconds).

I noticed that portSUPPRESSTICKSAND_SLEEP never get called, the only way to make it work is disabling the only task that i have in my test application. h> int usleep( useconds_t useconds) Arguments: useconds The number of microseconds that you want to process to sleep for. I have been able to work out the issue with the Xilinx lwIP.

FreeRTOS claims that waking up a task using the new notification system is ~45% faster and uses less RAM than using a binary semaphore.

These APIs are very mportant for programming. This is a constant value available via the Clock_tickPeriod variable. sleep() packages only allow a precision of 1/100 seconds. For that kind of stuff you probably will have to implement your own interrupt handling. This happens on both cores independently, and can not be configured. The sleep function is provided by the unistd.

It seems that sys tick handler blocks all interrupts and in result my timer does not work properly (I need microseconds precision).

IвЂ™m working on a FreeRTOS port for ATmega1284P and trying to save as much power as possible in the Tickless Idle Mode, but an obstacle appeared. Use the -l c option to qcc to link against this library. If you need to delay the job for less than a second, however, you must use the usleep() API.

That means, At the start, the software timer will expire after every one second for 5 times. 2, which allows longer sleep periods by shutting down the OS tick when it is not needed. It did not increase the sleep current which stayed at 1.In light sleep mode, digital peripherals, most of the RAM, and CPUs are clock-gated, and supply voltage is reduced.

I need to put our device into a lower power mode which involves changing the main clock speed to a lower value and restoring it upon waking. Enter the frequency in Hz at which the internal clock that drives the peripheral used to generate the tick interrupt will be executing - this is normally the same clock that drives the internal CPU clock. The ESP-IDF FreeRTOS is a modified version of vanilla FreeRTOS which supports symmetric multiprocessing (SMP). Or you can use a non-preemptive scheduler, and do exactly the same. Freertos sleep microseconds After injecting the elapsed ticks in deep sleep by the call to vTaskStepTick(), the crash is happening on the first Systick interrupt.
