Core dump for crash logs

[Ubaid_M]

Hello,

I am using nCS v1.9.1, have developed an application which is complete and during testing observed that at times it randomly crashes without any error log.
Tried debugging but still couldn't isolate the reason and trace the crash source.

Can you kindly suggest if anything like a core dump of crash logs available for tracing the source and reason for the crash..?

Thanks,

Hi Mohammed

I think core dump would be a good choice here. Zephyr has a good example on how to set up core dump which you can find here.

Hi Runar,

I am following the above document which you have mention. I follow the step 

1. after enable all the config, i am able to do coredump find , coredump verify, coredump print.

2. I copied the serial logs and and save as the coredump.log

3. i am able to convert the coredump.log to coredump.bin  using 1st command shown in the screenshot.
 

4. I have tried the 2 nd command for this i am getting the waiting for the gdb connection port.

5. I have tried 3 rd command gdb server is opening but for the after firing the 4 th command i am getting the connection timeout error.

please help me with this is i miss any steps in between. Some example code is there of this? i am referring this nordic ticket https://devzone.nordicsemi.com/f/nordic-q-a/101071/saving-coredumps-to-external-flash/448143

Hi Jyoti, 

If you could make a new ticket it would be awesome. We prefer to not mix different cases in the same case.
