nRF9160 Clock timing

[ephraim]

Dear Sir.

Attached a code .

It takes about 20 seconds from power on until the Blue Led is On.

The timing of the Blue Led is about 2 sec , as in the code.

Commenting all lines beside the io_init(); , a delay of 20 seconds is still on.

Please Advise.

void main(void)
{
      int err;
      static unsigned int i = 0;

//      k_work_init(&work_bz, work_bz_func);

      k_work_init(&work_top, work_top_func);
      k_work_init(&work_spi, spi_work_func);    
      k_work_init(&work_adp5360, adp5360_work_func);

//      k_work_init(&work_lis2dw12, lis2dw12_work_func);

     

      initStructures();
      
       _AFE4900_AQUIRE_MODE.aquire_mode =  afe4900_aquire_sample;

 //     k_timer_init(&bz_timer, bz_func, NULL);
 //     k_timer_start(&bz_timer, K_SECONDS(1), K_MSEC(50));

 //     k_timer_init(&my_timer, my_expiry_function, NULL);
 //     k_timer_start(&my_timer, K_SECONDS(TIEMR_INTERVAL_SEC),  K_SECONDS(TIEMR_INTERVAL_SEC));
 
      io_init();
 //     pwm_init();
      

      _BZ_SM.bz_state = BZ_silence;

       init_i2cx_spix();
 
       ADP5360_vbus_sense();
       ADP5360_Interrupt_Config();

       SetLed(BLUE,ON);
        k_sleep(K_MSEC(2000));
       SetLed(BLUE,OFF);
       printk("Just before sleep \n");

       while(FirstCharge == false)
       {
          k_sleep(K_MSEC(100));
       }

//       for (;;) {
//        k_cpu_idle();
//       }

       FirstCharge = true;

        printk("Right after sleep \n");
       BlipCycles(20);

Is there any blocking call to setup a LTE connection inside any of the functions called? Also setting it on before a lot of the calls can help you see where the time is lost in startup, by then turning it off where you now turn it on
