How to wakeup from vPortSuppressTicksAndSleep with blinky_rtc_FreeRTOS example?

[inghowe83]

Hi Nordic,

Here is my configuration:

HW: Customize nRF52840

SW: blinky_rtc_FreeRTOS_pca10056

Problem: The led blink for a few sec and the board went into vPortSuppressTicksAndSleep (Tickless Idle) and the led stop blinking. Please advice how can I change the setting to ensure as long there is led blink/activities the device won't enter tickless idle mode.

Please advice.

Have you changed anything in the software? 

The task led_toggle_task_function never sleeps also the timer created never expires, so I am not sure why your device does not wake up from the sleep.

Yes, I moved the following code

/* Initialize clock driver for better time accuracy in FREERTOS */
err_code = nrf_drv_clock_init();
APP_ERROR_CHECK(err_code);

into lfclk_init() function, and call it via main function.

The problem resolved when I move the code back into main function.
