Viewing NRF_LOG_INFO output

[morpho]

How could I view the logs outputted via NRF_LOG_INFO? Do I really have to set up the UART connection for it which means having UART driver in place?

Hi,

 

How could I view the logs outputted via NRF_LOG_INFO? Do I really have to set up the UART connection for it which means having UART driver in place?

It supports two backends to be defined in sdk_config.h:

NRF_LOG_BACKEND_RTT_ENABLED

or:

NRF_LOG_BACKEND_UART_ENABLED

 

By setting NRF_LOG_BACKEND_RTT_ENABLED to '1' (and disabling the UART backend), you can use JLink RTT Viewer to see your prints.

 

Kind regards,

Håkon

After setting the flags in sdk_config, I still don't see any prints in the RTT viewer with these settings

Hi,

 

Q1: Which project in the SDK are you testing with?

Q2: Could you please share your sdk_config.h?

 

Kind regards,

Håkon

0714.sdk_config.h
nRF5_SDK_17.1.0_ddde560

Any idea?

[Håkon Alseth]

The sdk_config.h looks good.

Did you try other examples with similar settings for RTT?

 

Kind regards,

Håkon
