Hard fault reported when NRF_LOG enabled

[Sreelakshmi]

Hello,

I am using SDK15.0.0 and nRF52832. Using Segger IDE on windows platform.

My project has to read Analog sensor input through SAADC and transmit the values using SPI.

I did compile and tested SAADC and SPI modules individually. It works. I enabled NRF _LOG and it also worked.

Next step, I wante dto merge both SPI and SAADC implementation as one project.

Created user specific SAADC files and SPI files. Created main.c file with user specific functions(SAADC and SPI)

I created user folders and added them in configurations. Compiled and tried to test. It works.

So far it is working all good. Now, I wanted to enable NRF_LOG option after merge. After merging files it doesn't work and I get Hardware default from file ses_startup_nrf52.s

Please help me

Hi.

You have to debug the hard fault in order to find out what went wrong, I suggest you take a look at this debugging guide and find out what caused the hard fault.

Thank you. Used NRF_LOG() before it was initialised with NRF_LOG_INIT   NRF_LOG_DEFAULT_BACKENDS_INIT().

Is there help or guide about how to use this NRF_LOG and related functions.

Hi.

I was out of office yesterday, so sorry for the late reply.

You could take a look at the library description for the logging module which you can find in the infocenter, here.
