Change ramlog to direct log writing in kernel 3.4.107

apollon77 · June 17, 2015

Hi,

I'm using the 3.4.107 kernel at the moment and I have also attached an HDD.

Now I have the problem that the CUbietruck get's unresponsive once every 1-2 weeks and because of the ramlog I have no logs to see what the problem is.

All services stop working, but power is still "on".

My only idea is to replace ramlog solution by "normal" logfile writing (and because I use an HDD it's maybe better to directly write on HDD in any case) to have infos when the machine crashes the next time.

What I do need to do for that (I'm not really a linux expert ;-) ).

Thanks for help.

Yes, I encounter this problem in recent build, but haven't got a solution yet. I thought it's related to hardware fail on some particular board. The problem could also be in U-boot.

100% working combination is kernel 3.4.106 with matched u-boot or older releases. I have zero problems with this, uptime several months.

To disable ramlog:

service ramlog disable
reboot

I am also working on to catch the bug, but it's a slow progress. Sometimes it works for weeks without a crash

apollon77 · June 17, 2015

Hi,

can I help somehow? On what logs I could check? I'm willing to support to catch it ... :-)

I found a way to monitor the hang-up, so I would be fine for now ...

I will let you know if I see anything in the logs when it happens again ...

Else I would need to do a kernel downgrade :-)

apollon77 · June 19, 2015

Hey Igor,

had a new crash just today. Any idea in which logs to check?

kern, messages and syslog don't show anything interesting.

Can I do anything to gather more logs?

BTW: in ramlog I see after disabling as you said above:

Jun 19 06:33:10 Error: ramlog is not running... [fail]

Igor · June 19, 2015

Hmm, I am not sure that you will find anything in the log. At least not in default user mode.

I am not a kernel debug expert, but I think looking trough this might be useful.

http://elinux.org/Debugging_by_printing

Regarding Ramlog. It's a bug which is safe to ignore.

apollon77 · June 19, 2015

Hm ... I don't understand a word in the link. It seems to me that this article is interesting for people that develop drivers and such :-(

How Do i downgrade the kernel to 3.4.106 together with all needed components like uboot and such? Is there an howto? Or is it the same as in FAQ to upgrade kernel?

Igor · June 19, 2015

How Do i downgrade the kernel to 3.4.106 together with all needed components like uboot and such? Is there an howto? Or is it the same as in FAQ to upgrade kernel?

Manual is in the FAQ but not sure if it's 100% valid for this older kernel. U-boot is not packed with kernel but separate.

http://mirror.igorpecovnik.com/kernel/3.4.106-cubieboard-default.tar

I can't find the exact u-boot, but try with this one.

http://mirror.igorpecovnik.com/u-boot/linux-u-boot-3.4.107-cubietruck_3.6_armhf.deb

apollon77 · June 20, 2015

Hm ... is the current 4.x kernel stable? Then upgrading to this would be an idea too ... most of the features listed as "not working" I do not need at the moment.

For this the FAQ is valid, correct?

Sergey11g · June 22, 2015

My Cubietruck unexpectedly dies as well once every 2 weeks. It would be great to figure out the reason of these crashes.

apollon77 · June 22, 2015

...and an Info on the "known issues" would be great too I think ... :-)

apollon77 · July 14, 2015

Hi Igor,

is the new "4.0" with Kernel 3.4.108 fixing these problems ?!

What needs to be installed? New Kernel, Rootfs ... UBoot too?

Igor · July 14, 2015

yes, I was stressing it for more than two weeks and it was stable.

u-boot is mandatory, kernel recommended, the rest is optional.

apollon77 · July 14, 2015

Ok, so I collect all the deb-Files ( so the ones in uboot plus kernel) and install them all as stated in FAQ ?! Correct?!

Igor · July 14, 2015

Kernel tar pack has it all except rootfs deb package which is anyway not needed in this case.

I got an error while running "dpkg -i linux-image*.deb":

Ok, that "again" error I get removed by removing the partly installed 3.4.108 by "dpkg -r linux-image-3.4.108-cubietruck", but initial error still occurs :-(

I boot from nand and everything else is on HDD.

and /boot is accessible and mounted rw and I get this when showing it after such a failed install-try:

Do you have any instructions for me to fix it ? Any help would be great!

Igor · July 16, 2015

Kernel installation is not yet ready for such scenario. I need to fix it.

The only thing you need to do is to convert zImage to uImage (inside /boot) and reboot:

mkimage -A arm -O linux -T kernel -C none -a "0x40008000" -e "0x40008000" -n "Linux kernel" -d vmlinuz-3.4.108-cubietruck uImage

apollon77 · July 16, 2015

So I simply ignore this install error? And use that command from you? Do I need to install al the other *.deb Files manually too?

Igor · July 16, 2015

Yes, ignore. Kernel post install script creates a symbolic link to installed kernel. This is not possible on FAT file-system which is on the first NAND partition /boot. I'll fix once that it won't show the error and that that this command will be executed automatically.

I am using NAND u-boot as is.

All other debs are more or less optional.

apollon77 · July 16, 2015

Great, will try tonight :-)

Should I install other deb Files too manually or is this already done by kernel-install?

Igor · July 16, 2015

Kernel install only kernel (and modules), dtb only dtb, uboot only uboot, headers only header, ... They are not linked together by purpose.

apollon77 · July 17, 2015

I only asked bacause in faq it says "if not installed automatically install some manually"

apollon77 · July 17, 2015

In general I only used the possibilities: install system to nand and then to sata ... and so I ended with this install situation .. is it not "as planned"?

Hm ... don't looks that successfull ... After doing that (install kernel, create that uImage-File, install u-boot, I run reboot and on shell I got some syslog-error.

Here is the full infos from my syslogserver (start reading at the end):

And now it wont reboot anymore :-(

BTW: I wonder: My /boot was 4% space used initially, after creating uImage it was 83% ... this means the next kernel update will don't work because now more space availabe ... How can I resite /book in nand?

Igor · July 18, 2015

What I can see from log is that you are booting kernel 3.4.107 which makes me think that you haven't used the proper kernel as source. Somehow the conversion from zImage to uImage was not made properly. This is necessary since we use the preinstalled NAND u-boot.

I'll recreate the exact scenario in next days to make sure this scenario works.

apollon77 · July 18, 2015

From my point of view these error happend on shutdown because when I try to restart I get simply nothing in syslog-server.

Ok, but what can I do now? The former uImage was only 64 byte in size, which looks more then a symbilic link size then like a correct size ...

I was able to use sd-boot to boot and mount the partitions. Interesting is the fact that the /nand/nand1 looks now as follows:

root@cubietruck:/mnt/nand1# ls -la
total 5666
drwxr-xr-x 3 root root   16384 Jan  1  1970 .
drwxr-xr-x 4 root root    4096 Jul 18 09:33 ..
-rwxr-xr-x 1 root root  118912 Nov 18  2014 boot.axf
-rwxr-xr-x 1 root root     106 Nov 18  2014 boot.ini
-rwxr-xr-x 1 root root       0 Jul 17 22:02 config-3.4.108-cubietruck
drwxr-xr-x 2 root root    2048 Nov 18  2014 linux
-rwxr-xr-x 1 root root     512 Jan  1  1980 magic.bin
-rwxr-xr-x 1 root root   46360 May 15 21:15 script.bin
-rwxr-xr-x 1 root root       0 Jul 17 22:02 System.map-3.4.108-cubietruck
-rwxr-xr-x 1 root root     281 May 15 21:34 uEnv.txt
-rwxr-xr-x 1 root root 5605360 Jul 17 22:02 uImage
-rwxr-xr-x 1 root root       0 Jul 17 22:02 vmlinuz-3.4.108-cubietruck

So the 3 new files that were installed with the kernel update have a size of 0 now, but "df" startes still 83% used space ... But uImage have correctsize as before after the conversion ...

Any idea how to restore it to the state before? Else I need to set up completely new :-(

One option is to boot SD image with 3.4.108 ...copy /lib/modules/*********-3-4-108 to nand2 and sda1, convert /boot/zImage to uImage with previously mentioned method and copy to NAND1 ... check uEnv.txt @NAND that it's pointing to proper root.

So do step by step. First boot from NAND and rootfs=/dev/nand2 ... than copy modules to HDD and switch rootfs there.

nand2 is empty (only a "lost+found" directoy is there ...

But you are right ... on sda1 the /lib/modules directory for 3.4.108 is not existing ... so the install of the linux-image that produced the "symbolic link error" above also did not copied these files correctly. Will try tomorrow if it works when copying them there.

Maybe convert was good but only those files are missing ... :-)

apollon77 · July 19, 2015

Hm ... it must have been too late yesterday ...

On sda1 the lib/modules directory for 3.4.108 exists and has all files. I have now unpacked the 3.4.108 deb file and used the file from there and copied again to nand1.

Will try to reboot tomorrow (can't get to the device to get sd card out :-) ).

Ok, have now installed from fresh sd-image 3.4.108 to nand2. With this nand1 (boot) got newly written too and then I only changed to root in uEnv.txt and everything went well.

I only needed to deinstall the only partially installed 3.4.108 kernel-image from hdd and copy the /lib/modules-Files again but after that now my old system is back :-))

Thank you for all your help ... hopefully you can reproduce.

I I can help in testing or such simply tell me !

Igor · July 20, 2015

I know now what's the essential problem and it will be fixed. NAND/SATA/USB install part is as is. If you follow the install it works, It fails in custom situations - It's not designed for that yet.

I am glad everything went o.k. and thanks, testing is always helpful and saves a lot of time. Mine and all users if we discover and fix thigns propmtly.

Hey Igor,

bad news, had the same effect today with kernel 3.4.108 :-( system just halted, no services responded. Just like with 1.3.107 :-( Any idea on it?

apollon77 · July 30, 2015

Did you delete your last post with question on uboot?

I had installed new uboot as I tried to upgrade to 3.4.108 from 3.4.107. worked without an error.

Then I needed to setup /boot newly from sd with the 3.4.108 image if you remember ... is uboot on that or not?!

Do I need to install uboot packet manually now (again)?
