Using RTT viewer in SDK 12.2 SES

[khosla]

sdkconfig.txtmainc.txt(/attachment/6fb97103178e9eb2c30302351e63ce8f)Can you please tell whether i follow the the entire tutorial as in the link or just the first step for SDK 12.2 SES. Even if i use the first step, i need the CMSIS wizard that uses Java tool to modify the functionality in sdkconfig.h to enable logging through the RTT viewer.

But somehow there is a problem with opening the .jar file, since Java tool is not working for my windows.

Is there an alternative way to modify the sdkconfig.h, not manually, as there are chances of errors coming up if i change it myself, then there will be further problems

Hi,

It should be sufficient to enable NRF_LOG in sdk_config.h and set the backend to use RTT.

I'm not aware of any other tools that can edit the CMSIS files, except Keil and CMSIS Configuration Wizard. Why not try to undertand how the file works and fix the errors instead of looking for another tool? The documentation can be found here, and on the Keil page linked there. If you have some issues, post it here and I will try to help you solve it.

To enable logging over RTT, set the following defines in your sdk_config.h file:

#define NRF_LOG_ENABLED 1

#define NRF_LOG_BACKEND_SERIAL_USES_UART 0

#define NRF_LOG_BACKEND_SERIAL_USES_RTT 1

If you have enabled deferred logging by setting #define NRF_LOG_DEFERRED 1, you need to call NRF_LOG_PROCESS() or NRF_LOG_FLUSH() in you main loop, to process the log queue.

Best regards,

Jørgen

Please upload your main.c and sdk_config.h file, and specify which example you are using. Note that the information in the tutorial does not apply if you use NRF_LOG for RTT printing.
