the log is from the boot, earlier log entries are lost during restart.

3

thanks for your reply , i didnt know that , is there anything i could do that my device wont restart and work normally ?

4

without additional info, no really.

post the output of ubus call system board to start with.

5

i am not sure where to find this section in my router , can you please tell me where to find it ?

6

you need to run the command ssh:ing to the router.

try ssh root@<IP.of.the.router> from a command prompt, password is the same as for the webUI.
or DL putty, is user friendlier.

I'd probably start by upgrading to 22.03.5, or 23.05.2, and resetting in the process.

once done, ssh to the router again, and run logread -f, and keep the command running, hopefully it'll catch something before a restart.

Support for ramoops has been added to the latest OpenWRT release: Link

cat /sys/fs/pstore/dmesg-ramoops-0
cat /sys/fs/pstore/console-ramoops-0
