logs are attached, i have updated also tell me

  1. difference too among these files.
  2. does it store all the ramoops or is there space limitation.
  3. i have shared the logs of the nano which was deployed in the truck last week…but when i mount to pstore i can see only latest current todays’s logs…why there are no last weeks one???
  4. i have also observed that after reboot, the previous logs files vanished…how to store each and every log…because remote nano rebooted many times and we want each log to find out the cause…

[ 412.128573] sysrq: Trigger a crash

It looks like you are trying to boot from sdcard but sdcard has file system crash.

24

this crash was explicitly created by me

echo 1 > /proc/sys/kernel/panic

Trigger panic via sysrq

echo c > /proc/sysrq-trigger

25

Then you should recover your board and just leave your board there until the next crash happened.

Hi,

What you are asking are the nature of ramoops. It will only record once.

If you think this does not match what you need, get your device back and connect with UART serial console.
Run the application and see if that hit the issue.

isnt there any way to store all logs which cause the system to crash remotely and i can see when device gets back???

There is no this mechanism in system sw currently, may other developers help to share ideas.
