Hello ,
I am using NRF 52 DK board and SDK15.3.0 .
I have tested \examples\peripheral\blinky_freertos code and its working fine .
but the same code ( in that code , one task ans one timer is created ), if I port to examples\ble_peripheral\ble_app_hrs code ( added NRF_LOG_INFO in the timer callback instead of led toggle ). It works for once and shows hardfault error.
Below is the code I am running
main(){
bool erase_bonds;
log_init();
clock_init();
//xTaskCreate(pixart_task, "Pixart_sensor", 300, NULL, 2, &handle_pixart_task);
timer_handle = xTimerCreate( "timertest", 5000, pdFALSE,NULL, led_toggle_timer_callback);
if(timer_handle != NULL){
xTimerStart(timer_handle, 0);
}
/* Activate deep sleep mode */
// SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;
vTaskStartScheduler();
//===============================================================================================
for (;;)
{
}
}
and below is the error I am getting :
<info> app:
timer callback 1 >>>>>>>>>>>
