RouterBOOT always using backup booter

Mon Aug 22, 2016 4:49 pm

I have a RB3011 device which was appeared to be stuck at "ether boot".
It appeared that connecting a cable to the eth1 interface eventually caused it to boot anyway as this causes it to attempt bootp.
I took a serial cable and connected it, only to see that it keeps using the "RouterBOOT backup booter 3.27" and not the main booter.

What could be the cause for this?
- There is no configuration that forces the backup booter
- The reset button is not stuck.

I tried a couple of things, including upgrading the RouterOS software and RouterBoard firmware, to no avail.
I also used NetInstall to reinstall the RouterOS software but this did not help either.

This is what the complete reboot and bootup cycle looks like from the serial terminal:

Rebooting...
Stopping services...
Restarting system.


RouterBOOT backup booter 3.27

RouterBOARD 3011UiAS

CPU frequency: 1400 MHz
Memory size: 1024 MiB
NAND size: 128 MiB

Press any key within 2 seconds to enter setup
Please, check ethernet cable... <<< plugging in a cable on eth1 OR pressing enter causes bootup to continue.

You have probably configured the bootloader (/system routerboard settings) to first boot from ethernet instead of nand.

Try changing the boot device. Run this from terminal:
/system routerboard settings set boot-device=nand-if-fail-then-ethernet

Thanks Cha0s for your reply.
But I already tried that. No luck.

These are the current settings:

[admin@MikroTik] > system routerboard settings print
baud-rate: 115200
boot-delay: 2s
enter-setup-on: any-key
boot-device: nand-if-fail-then-ethernet
cpu-frequency: 1400MHz
boot-protocol: bootp
enable-jumper-reset: yes
silent-boot: no
protected-routerboot: disabled
