does someone know what can make the router stop working?

is there any way to know ?


RouterBOOT booter 3.18

RouterBoard 411U

CPU frequency: 300 MHz
  Memory size:  32 MiB
    NAND size: 128 MiB

Press any key within 2 seconds to enter setup..

loading kernel from nand... OK
setting up elf image... OK
jumping to kernel code
^Copendir: No such file or directory
opendir: No such file or directory
ERROR: no system package found!

There are many different reasons and you have to diagnose it on a case-by-case basis. In your particular case, it seems safe to say that it is a result of filesystem corruption, or a bad NAND. You will need to re-Netinstall RouterOS, and if that doesn’t work, then you have a bad board (though I’m about 95% confident Netinstall will fix it).

I know the NetInstall will fix fix it , I want to know what is the reason for the crash , so I will be able to avoid it in the future

“ERROR: no system package found!”
The boot process cannot continue because important system files are just missing.

5

what can cause it go missing?
no one can enter the router (except me) and change\remove packages or something

Thanks,

As Nathan said - most probably filesystem corruption.

but again , what can cause a filesystem corruption?
1-2 examples if you can

Thanks ,

Writing to it during power loss. High power electromagnetic pulse. Are these examples acceptable for you?

high power pulse is seem logic
I’m using a 26V power , so it is possible…

Thanks ,

SImple power outage and BOOM! Bad blocks, corrupted files etc.

4 Years later… Still the best little thread I’ve come across. :slight_smile: RB2011 ate crap after a POE power outage/spike recently. Seems they don’t like HV/POE issues.
