SPIS Nrf log enabling problem

[Ozil 11]

I'm trying to print received data on my com port but when I set the  "NRF_LOG_ENABLED" as 1 the error below shows up.

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_log_default_backends_init (referred from main.o).
Not enough information to list image symbols.
Not enough information to list load addresses in the image map.

What does it mean?? How would I know what files to include. I then though I could use "printf()" command to do the same but it shows similar error. I included all the files which support uart into it. I'll mention below just to be sure:

In nRF_Drivers:

app_uart_fifo.c

nrf_drv_uart.c

in Libraries:

app_fifo.c

I included the path of those drivers and libraries too.

Hello Mesut,

 What example or template project are you using as starting point?

 I assume that you have read the documentation behind the Logger module?

I would recommend you to take a look at the "ble_app_uart" example found in: [<SDK_InstallFolder>\examples\ble_peripheral\ble_app_uart ]. 

Note the files included in the nRF_Log folder and compare your sdk_config.h file to see if you are missing something. I suggest you use the template "sdk_config.h" found in:  [<SDK_InstallFolder>\config\].

Hey Martin,

Thanks, there is no error now. I'm using the SPIS code from SDK14.2 . I wanted to see the received data on my com port, but I couldnt even after enabling the Nrf_Log_Enable in the sdk_config.h

You must also enable the log in sdk_config.h. Make sure that you have NRF_LOG_ENABLED 1 and NRF_LOG_BACKEND_SERIAL_USES_UART 1.

To view or write data over the Virtual COM Port, you need a terminal program, such as Termite. You can download Termite here. 

Remember to select the correct settings in Termite

I did it and still nothing. I'm using teraterm. (checked the settings as well and selected the proper baudrate)
