Thanks Runar for update,
I'm currently working on enabling modem trace logs for the nRF9160 using nRF Connect SDK version 1.7.0 and modem firmware version 1.3.0. I’ve followed the recommended configurations by adding the following macros to my prj.conf file:

# Enable modem trace CONFIG_NRF_MODEM_LIB_TRACE=y # Select the backend for trace output CONFIG_NRF_MODEM_LIB_TRACE_BACKEND_RTT=y

However, I am encountering the following errors:

prj.conf:189: warning: attempt to assign the value 'y' to the undefined symbol NRF_MODEM_LIB_TRACE error: Aborting due to Kconfig warnings CMake Error at C:/H565935/CL5G_R200/zephyr/cmake/kconfig.cmake:268 (message): command failed with return code: 1 Call Stack (most recent call first): C:/H565935/CL5G_R200/zephyr/cmake/app/boilerplate.cmake:554 (include) C:/H565935/CL5G_R200/zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:24 (include) C:/H565935/CL5G_R200/zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:35 (include_boilerplate) CMakeLists.txt:31 (find_package) -- Configuring incomplete, errors occurred!

It appears that the NRF_MODEM_LIB_TRACE and NRF_MODEM_LIB_TRACE_BACKEND_RTT symbols are not recognized. Could you please provide guidance on how to properly enable modem trace logging with this SDK version? If these features are not supported in SDK 1.7.0, is there an alternative approach.

Thank you for your assistance.

Hi

Try to use CONFIG_NRF_MODEM_LIB_TRACE_ENABLED instead of CONFIG_NRF_MODEM_LIB_TRACE. If you want RTT you can use CONFIG_NRF_MODEM_LIB_TRACE_MEDIUM_RTT

Hi,

As mentioned above i have used CONFIG_NRF_MODEM_LIB_TRACE_ENABLED  and CONFIG_NRF_MODEM_LIB_TRACE_MEDIUM_RTT, but i was facing below error

Error

It appears that the linker is unable to locate the SEGGER_RTT_ASM_WriteSkipNoLock function, can you help to solve this issue.

Thanks and Regards,
Pradeep Gamidi.

Hi

I need to check regarding the SEGGER_RTT_ASM_WriteSkipNoLock. However regarding CONFIG_NRF_MODEM_LIB_TRACE_ENABLED=y is not the same as CONFIG_NRF_MODEM_LIB_TRACE=y
