Hi folks.
There are some errors on Mikrotik AC2 and freshly installed OpenWRT 24.10.4.

Can anybody check these errors and explain them, please?

Thanks in advance!

1st group - dts has different definitions for same partitions, since it boots at all there is no problem.

2nd overlay filesystem got initialized on first boot, will not happen again

tmpfile messages - jffs file system does not support tmpfile call, will work anyway.

Great, thanks. I thought that I faced with some NAND issues.
So everything fine and I'm happy.

I'd like to avoid to create new topic, so I'll ask here.

There is another issue with that Mikrotik. Sensors app stopped to show temperature.
Everything was fine on 24.10.2 and when I installed 24.10.4 it was working for some time, but now I'm getting that

any ideas how to check or fix that issue?

Thanks in advance.

Should be steadily shown.
Maybe swap driver + firmware to ones without -ct , if neither works report a bug/regression on gh.
(wifi device and driver includes temperature sensor)

6

What is ct? And how can I swap driver?

The problem is is fact, that is was working on 10.4 at the beginning! I configured collectd to collect data. But then temperature graph disappeared.
Tried to reboot router, but nothing has changed.

It was my stupidity. I totally forgot, that wireless interfaces were disabled on that router. And there are couple of them in a remote location....So the issue is resolved. Sorry for wasting your time.
