Hello.
I am trying to use FreeRTOS and have run into a problem. If I call logging in the FreeRTOS software timer handler, the program stops.
Here is a simple example:
#include <stdbool.h>
#include <stdint.h>
#include <string.h>
#include "nrf_drv_common.h"
#include "nrf_log.h"
#include "nrf_log_ctrl.h"
#include "nrf_log_default_backends.h"
#include "FreeRTOS.h"
#include "timers.h"
#include "task.h"
volatile TimerHandle_t xOneSec_Timer;
void blink_task(void *p){
while(1){
NRF_LOG_INFO("Blink");
vTaskDelay(1000);
}
};
void vOneSecTimer( TimerHandle_t xTimer ){
configASSERT( xTimer );
NRF_LOG_INFO("Timer");
}
int main(void)
{
ret_code_t err_code;
// Initialize.
err_code = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(err_code);
NRF_LOG_DEFAULT_BACKENDS_INIT();
NRF_LOG_INFO("Start");
for(uint32_t i=0; i<20; i++){
NRF_LOG_INFO("Count %d",i);
for(uint32_t k=0; k<0x100000; k++){__NOP();};
}
xOneSec_Timer = xTimerCreate( "1STimer", 1000 , pdTRUE, NULL, vOneSecTimer);
xTimerStart(xOneSec_Timer,0);
xTaskCreate(blink_task, "Blink", 256, NULL, 2, NULL);
vTaskStartScheduler();
while(1);
}
The output to the Ozone terminal looks like this: I see a "Start" message, messages with a counter, but as soon as the timer handler is called, the program stops. If in the timer handler you do not call a log entry, but for example blink the LED, then everything works. I see messages from the blink task and blinking LED.
What am I doing wrong?
