We are using the chip of the GR5513.

There is the simple code inherited from the rtos sample. When I using the UART mode, It can be fast output on the terminal, but when I selected RTT, the output in the terminal was too slow. The duration of the two items about 1s.

What's different between of them.

static void vEmpty(void *arg)
{
	while(1)
	{
		APP_LOG_INFO("%s: %d\r\n", __func__, __LINE__);
		app_log_flush();
		vTaskDelay(10);
	};
}

	APP_LOG_INFO("\r\nBuild: %s-%s\r\n", __DATE__, __TIME__);
	app_log_flush();
   
	xTaskCreate(vEmpty, "empty", 512, NULL, configMAX_PRIORITIES - 1, NULL);
    vTaskStartScheduler();                                          /*< freertos run all tasks*/
