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.
