If i reboot, it fails. If I turn it off and turning it back on, it works.

From serial terminal:
==================

Hello again,

Seen here: http://forum.mikrotik.com/viewtopic.php ... 42#p353357
Make sure reset jumper hole (http://wiki.mikrotik.com/wiki/Manual:Password_reset) is clean and both sides are not connected with metallic object. It can make configuration reset on every reboot.
Perhaps during the last operations the reset button was not really jumping back or out and now the RB1200 is booting
even and even more?
No.
The problem is intermittent and RouterBoard was not open.
The problem is either in the factory or is firmware 3.2!

Who can send request to support@mikrotik.com to try to debug this problem?

I have my 3 RB1200 1000Km far from me.

My solution:

downgrade to 5.11, downgrade routerboot, change RAM module to kingston 2gb.

Now it has 5 hours uptime...I tried to reboot it 3-4 times....everything OK. I will see tomorrow.

Re: RB1200 do not reboot, stopped on: jumping to kernel code

Tue Apr 09, 2013 5:07 am

Took delivery of my first RB1200. The first two times I applied power, it failed to boot: no initial beep, not even output to the serial port. The third time it booted into RouterOS normally. After / system reboot, it stopped after displaying "Restarting system." and I had to remove & reapply power--which occasionally works, but usually does not.

Overall I'm seeing ~90% failure to run the boot loader upon power-up or reboot command. I see a slightly better rate if I hold down the reset button to force the default boot loader, but even that fails to load much of the time. Sometimes the green LED will come on and stay on; sometimes it doesn't come on at all. Rarely, the boot loader will start but print garbage rather than the "MikroTik" logo, sometimes it says "not an elf header" and tries bootp, then locks up before it finds the netinstall machine.

None of the following measures have made any difference:
  • upgrade to ROS 5.24 (boot loader 3.02)
  • downgrade to ROS 5.22 (boot loader 2.38)
  • downgrade to ROS 5.11 (boot loader 2.37)
  • using the reset button to force the backup boot loader
  • reducing CPU speed to 666MHz
  • format NAND
  • force backup-booter loading (from the boot menu)
So... does any of this look wrong (particularly the PCI settings)?

Re: RB1200 do not reboot, stopped on: jumping to kernel code

Tue Apr 09, 2013 4:38 pm

After (re)installing 5.24 and the 3.02 boot loader, I ran a series of tests last night. 11 of 34 cold-boots failed, and 15 of 36 soft-boots ( / sys reboot ) failed. In every case, the failure occurred before the boot loader was able to send anything to the serial port. Conversely (or contrapositively :) ), if the boot loader launched successfully, it would reach the ROS login prompt every time.

It didn't seem to matter how long the box was left powered on or off, or whether it was a cold-boot or a warm-boot, so I don't think it's a heat issue. It is as though the main board or memory board has an intermittent, low-level problem (race condition?) that makes it a coin-toss whether the boot loader will launch or hang.

At this point it's a curiosity, as I will be returning this box--but now I'm concerned that this might be a systemic problem that affects a certain production run, rather than an isolated defect. FTR, the serial number of this particular unit is 2D720112642D/121, and the MAC range is 00:0C:42:CF:30:9A - A3.

I have 2 pieces od RB1200 on the desk. Both are freezing + failed booting :(.... no answer from Mikrotik.

//if you change original 512mb ram to kingston 2 GB ...random rebooting will disappear. But I havent got enough courage to deploy it on network.

//with original 512mb ram...router upgrade from 5.11 to -> 5.24 will fail on boot...kernel error..now with 2 gb ram upgrade from 5.11 to 5.24 without any problem...

I'm having the same problem. Just bought an RB1200, upgraded to 5.24 - rebooted - it won't boot. Had to disconnect and reconnect power to boot it. Upgraded firmware to 3.02 and rebooted (again, had to disconnect and reconnect power to boot it).

But now reboots are working (tried 5 times in a row, it reboots ok now). I'll leave it running overnight to see if it reboots like the ohters have mentioned. Damn, I planned to deploy this one on site today.

Re: RB1200 do not reboot, stopped on: jumping to kernel code

I have a similar problem, Brand new RB1200 that I upgraded all packages to 6rc14.

The unit will reboot on command, but if I shutdown or power off the unit it will not boot unless I hold in the reset button and then plug in the power. The unit beeps after a few seconds and then boots ok.

Is there any fix for this if there is a power cut and the UPS runs dry then some has to go to site and pull it out of the rack and push the button!

Thanks,

Guy

Update - the unit does reboot, it just seems to take 60-90 seconds before it 'beeps'.

I'm happy enough :lol:

Same problem here with brand new RB1200 - as in same as Hotz1 is getting: randomly on reboot the system never starts up, with no output on the serial terminal at all after "Restarting system."

If the boot starts, everything works perfectly. If boot doesn't work, pull power and reinsert has worked each time. Failure to boot seems to be about 1/3 of the time

Experienced the problem on all of these so far (in order):
Original firmware as shipped 5.11, boot 2.37
Upgraded ROs to 5.24, boot 2.37
Upgraded bootloader to 3.02, still ROs 5.24
Upgraded to ROs 6.2, upgraded bootloader to 3.07

After going to 6.2/3.07, problem seems to be less...maybe 20% of reboot attempts lead to no boot...but that's anecdotal on only about a dozen reboots.

I haven't tried any downgrades, reducing CPU freq etc., as these don't seem to have any affect for anyone else.

Re: RB1200 do not reboot, stopped on: jumping to kernel code

Wed Jan 08, 2014 2:46 am

I'm reviving this thread because I have taken delivery of another RB1200, and it has the exact same problem with intermittent lockups during reboot as the last one I bought: Typically, it will successfully reboot two to four times in a row before it fails to complete the boot process--at which point the only way to recover is to physically cycle the power.

As before, there is no crash output or error message on the console; it simply stops printing to the console after "jumping to kernel code". (Sometimes, upon being sent the reboot command, it locks up after printing the "Restarting system." message to the console, and never even gets back to the boot loader.)

This pattern holds whether running ROS 6.7, 5.26 or 5.18 (and their corresponding boot loaders). Sometimes it even fails on the first try (initial power-up), and will even fail within a minute of powering up from room temperature, when the heat sink is still barely warm; i.e., it doesn't seem to be heat-related.

On those occasions when it does reach the login prompt, everything seems to be fine; i.e., no crashes or sudden reboots or watchdog timeouts, just normal operation.


Oddities when running ROS 6.7/3.10:
ONCE I got the following message after "jumping to kernel code":
Initramfs unpacking failed: no cpio magic
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Rebooting in 180 seconds..

TWICE, after locking up, it jumped on its own back to the boot loader after a few seconds, and completed the boot on the second attempt. On every other occasion that it has stopped indicating progress through the boot, it has failed to recover on its own, even after sitting for over 50 minutes on one occasion.


The serial number of this unit is 2D72011DF4B9/121, and the MAC range is 00:0C:42:C0:AC:0E - 17. (It isn't the same one that I bought before, as I posted earlier. That's why I came back to this thread in the first place: to make sure I hadn't been sold the same lemon as last time!) I have yet another RB1200 on its way, which should be arriving toward the end of the week, and will receive the same degree of scrutiny. If it has the same problems, that will mark the end of my involvement with RB1200s, at any price.

I had hoped that MT would have found it worthwhile to try to identify the problem with these particular boards, and either release (software) or describe (hardware) the fix, or pronounce them irreparable and put an end to the mystery once and for all. Best of all would be to identify a bad run of boards or components, so we could identify the bad ones without having to buy/test/return them. Instead, the main thing I see is that all mention of the RB1200 is scrubbed from routerboard.com, even from the archive section, where older hardware is still listed.

Re: RB1200 do not reboot, stopped on: jumping to kernel code

Tue Jan 21, 2014 7:36 am

For the record: I just took delivery of my third (used) RB1200, and this one has yet to lock up mid-boot. I can put it on a loop that sends it a reboot command via ssh every 15 seconds, and it will keep going for as long as I can stand the beeping. :-)

So, that rules out a software/configuration issue, and suggests a bad run of components or assembly.

FWIW, this working unit's serial number begins with "306E", whereas the two devices that I have had with this boot problem begin with "2D72". Also, the MAC address for the working example begins with D4:CA, rather than 00:0C like the other two. If anyone else has serial number/MAC info for RB1200s with this booting problem, or any info at all about why some of these devices have chronic intermittent boot problems, please post it here!

Here's a new one from the RB1200 with the intermittent boot failure, after having been given a "/system reboot" command:

After the usual "jumping to kernel code" message, it says,
  • /bin/bash: symbol 'll_tzname_UtC': can't resolve symbol in lib '/lib/libc.so.0'.
    Power down.

Im also having rebooting issues on a SER:2D72xxxx... unit with FW:3.10.

I first noticed it when I upgraded from 6.5 -> 6.9 then again through to 6.11 after a power cycle its normal again.

Same problem on RB1200 with FW 3.10 ROS 6.24 (and earlier versions starting from some 5.xx, I didn't have 4.xx on this board).
Serial: 2CD4*
On every single routeros upgrade I need to power cycle device cause it's not booting. I tried to wait for minutes to boot, still no luck.
