NRF_LOG_INFO messages on SDK 15. Please Help

[Wael]

Hi:

I am fairly new to Nordic so please excuse my ignorance. I recently took over a project which used sdk 11 and I am in the process of updating it to 15 and want to see the NRF_LOG_INFO messages. I am using keil 5 as my IDE and a j-link plus emulator. please note that I am NOT using a Dev board but rather our production board which currently does not have the uart tx/rx lines connected. I was able to view printed messages using the segger_RTT function in the previous project without having the urt tx/rx lines. Do I need to connect these lines in order to use the keil built in terminal or termite? I have enabled  NRF_LOG_ENABLED in the sdk_config.h file but I do not see NRF_LOG_BACKEND_SERIAL_USES_UART. I do not see com port on my PC device manager like I do when I plug the dev board in. any and all help would be greatly appreciated. I have read everything on the board relating to this but do not see much help with regards to sdk 15.

Regards,

Same issue here, it is not working on SDK 15. I have the backend rtt enabled and uart disabled and do not see anything in the RTT terminal.

Just took over a project from SDK 11 and updating it to SDK 15 and having so much troubles... How is this possible...

I would recommend that you create a new case where you described your issue in detail. You should also include code showing your configuration and initialization of NRF_LOG. The current implementation of NRF_LOG was not available in SDK 11, so this is a new module that you need to add to your project. Please have a look at existing examples in the SDK that use NRF_LOG module, and make sure you use the same config/initialization.
