freertos & logging

Question

Hi All, 
 I would like to use FreeRTOS in my project. I try to play with the examples/ble_peripheral/ble_app_hrs_freertos project. 
 I have enabled logging with RTT. The program is working well, I can connect with JLinkRTTClient and I have seen log messages. And when I try to logging in a task ble_stack_thread function for example the first line of function: 
 NRF_LOG_INFO("Task started
"); 
 it goes to HardFault_c_handler with address 0x20002db8.
When I comment this log messages it works well. 
 It seems to be some problem with FreeRTOS and logging. 
 I changed port_cmsis_systick.c as suggested here: devzone.nordicsemi.com/.../ 
 I use Debian Linux/Eclipse and SDK version is: nRF5_SDK_12.3.0_d7731ad 
 thnx

Hi Bjorn, I downloaded the nRF5_SDK_14.0.0_3bcc1f7, but in this example contains only one task, which is the logging task:( The ble funcionality doesn't run in a task. It should be good. And I make a new task like this: #if NRF_LOG_ENABLED // Start execution. if (pdPASS != xTaskCreate(logger_thread, "LOGGER", 256, NULL, 1, &m_logger_thread)) { APP_ERROR_HANDLER(NRF_ERROR_NO_MEM); } #endif if (pdPASS != xTaskCreate(alive_thread, "alive", 256, NULL, 1, &m_alive_thread)) { APP_ERROR_HANDLER(NRF_ERROR_NO_MEM); } and the task code is like this: static void alive_thread(void *arg) { UNUSED_PARAMETER(arg); int i=0; for(;;) { bsp_board_led_invert(BSP_BOARD_LED_2); vTaskDelay(500); if (++i<10) continue; i=0; NRF_LOG_INFO("tick "); } } Unfortunately I got the next message in serial console: nrf_sdh_freertos: SoftDevice task not created. app: Fatal I used make flash_softdevice and make flash. thx, Zamek
