Cubietruck SD-card or power supply or whatever - need some troubleshooting advice

[AlbertB]

Hi everybody,

I am looking for some advice and help for troubleshooting.

Here is the current situation regarding my cubietruck:

I have installed Armbian Stretch (mainline kernel 4.14.y or 4.17.y) from here https://www.armbian.com/cubietruck/ on a SD-card using etcher on Ubuntu. If I power up the cubietruck 3 out of 5 times it won't boot. If it starts I can just fine ssh into the system and everything seems to be o.k. But after some time if I start to do something e.g. apt-get update / apt-get upgrade the system will freeze at some point. If i let the cubietruck on it's own it'll run for several hours without freezing. So the problem seems to be related either to CPU usage or SD-card i/o.

As the most similar issues seem to be related either to power supply or SD-card I have already tested some things:

• I tried different ac/dc connectors. One 5V 2000mA and the other 5V-5.25V 3000mA -> same behaviour.
• I tried 3 different SD-cards. One made by Kingston (8GB) and two made by Samsung (16GB) -> The Kingston card works better than the Samsung cards. I would say Kingstob boots about 40% of the time. Samsung cards seem to boot only about 20% of the time. All of them seem to work flawlessly with a Raspi 2 (with Raspbian installed).
• I tried to check /var/log/messages after freezing by removing the SD-cart form my cubietruck and review the filesystem on my PC. But there is no messages file. This might be due to the way Armbian mounts /var/log to some kind of RAM disk so no hints from there.

Where to go form here? Test a third kind of SD-cards? Try a different operating system? Are there any debug tools in Armbian that could give me a hint?

 

Best regards,
Albert

Hi Albert,

 

Welcome to armbian.

It is nice to see, that you read about 'how to burn the SDcard' and are also aware of power & SDcard issues.

Reading your comment, once you put load on your SoC = it draws power, your board freezes.

Do you own, or can you borrow a Voltmeter or Multimeter to measure the voltage directly on the board and see if it drops once you start apt-get update?

 

Cheers

Tido

Hi,

 

I own a multimeter and I could try to do it. Can you show me where to measure? Google hasn't been too helpfull for me.

 

In the "How to provide and interpret Debug output" thread I red that armbianmonitor might be able to give DC values somehow. See:

Maybe I could open two ssh sessions and run armbianmonitor with some kind of voltage option in a loop in one session and start apt-get in the other session.

 

Regards,

Albert

[Tido]

This is easy, you go on the website of Cubietruck, search the PIN-header for your device and there you find 'ground' and '5v+'  on these you attach your Multimeter.

Sei einfach vorsichtig, damit du keinen Kurzschluss machst.

No need for an "option" since A20/AXP209 boards like CT are detected automatically. Simply run

armbianmonitor -m

or even better

armbianmonitor -u

(since this contains also voltage information for exactly this reason). Thousand of answers here in this forum are wasted just because users are not encouraged to always provide 'armbianmonitor -u' output first. Not even moderators follow this simple rule  

[AlbertB]

Here is the output of armbianmonitor -m during apt-get upgrade until it freezes:

Well, there is no drop of DC-IN and temperature isn't raising either. How reliable are these values?

By the way this is where apt-get upgrade stopped:

WTF should I, more often than not is the reporting of onsite values WRONG !!!  written by TK himself more often than not.

So you take a Multimeter and find it out yourself.

Thank you. Voltage/temps look ok but there is a kernel oops reported. Next try: please run in one shell now

dmesg -w

and in another

armbianmonitor -v

(package integrity check which indicates problems with corrupted filesystems or SD cards)

[tkaiser]

The image you're using is from January this year so already containing our DRAM clockspeed adjustments. Might be worth a try afterwards with memtester (apt install memtester)

[AlbertB]

Thank you for the help. Here we go:

Only that there's no filesystem corruption. Running out of ideas other than trying now memtester as next step.

 

Still there was a kernel oops before in armbianmonitor -u output so there's something wrong:

Your DC-in value is always way below 5V. Therefore I would think that my issue isn't reladed to my ac/dc adaptor.

Yes. Some people reported problems with kernel 4.14.y Try modern 4.18.y kernel/u-boot (armbian-config->system-> alternative kernels -> DEV) combo before changing cables and PSU.

O.k. how can I change this in a headless environment? As menitoned above I installed Stretch from here https://www.armbian.com/cubietruck/.

armbian-config is CLI tool. SSH to machine and run it.

[AlbertB]

armbian-config -> System -> Switch gives me "No alternative kernels available".

[Igor]

Switch to nightly before and make sure to run apt update before ...

Now switch to DEV alternative kernel. It shpuld be 4.18.something

If I remember correctly I tried this yesterday after switching to nightly build and armbian-config -> System -> Switch still gave me "No alternative kernels available".

Try again and make sure you read my previous comments. I have no more ideas. It should work this way. In case you failed, there are build tools: https://github.com/armbian/build  Build from sources.

I checked again -> armbian-config -> System -> Switch -> "No alternative kernels available" message. So I am very sure now.

Before that I first executed "apt update" and then used armbian-config to switch to nightly builds. Was this the right order?

 

I wonder when the additional kernel should get on the system. Does the SD-card image contain different kernel versions? or do you expect "apt update" to pull more kernels?

Running out of ideas. Starting from a clean image must work. 

[AlbertB]

Is there a SD-card image of Armbian with a legacy kernel or with the 4.18 kernel? I would give it a shot with a different kernel.

 

I also played around with the build environment but wasn't able to choose a different kernel anywhere. (See attachment)

Because 4.18.y is development kernel and not for end users. You need to build with extra parameter EXPERT="yes" and choose DEV kernel at kernel selection.

Everything that its premade is there: https://dl.armbian.com/cubietruck/archive/

I think there might be an issue with my sd-card slot. Therefore right now I am trying a different approach. I installed Cubieez (from here ) following these instructions directly to NAND. My cubietruck boots now every time without any issues. Heavy CPU load doesn't seem to freeze it anymore.

 

Now I'd like to move the operating system to a usb drive (maybe later on a SATA drive) and run the cubietruck from there. I found some instructions here but I am stuck because I cant find uEnv.txt anywhere on my Cubieez install.

[AlbertB]

For another try I installed Arch for ARM on a SD-card (see: instructions). It boots every time now and won't freeze under load. I am a bit confused now. The very same SD-card didn't work well wit Armbian but does work witch Arch Linux. Or might the newly installed NAND make a difference? It shouldn't because as far as I know the system boots directly form SD-card without touching NAND if a card is present.

[Igor]

Please provide more information, which kernel and which u-boot at Archlinux, which on Cubeez (from 2014!). Talking about some other distribution names tells exactly nothing. In your case, serial console log (when it doesn't boot) would provide some valuable clues.

Hi Igor,

 

here some information regarding Arch:

[alarm@alarm ~]$ uname -a
Linux alarm 4.18.5-1-ARCH #1 SMP PREEMPT Fri Aug 31 01:05:38 UTC 2018 armv7l GNU/Linux

u-boot was this (downloaded yesterday) : http://os.archlinuxarm.org/os/sunxi/boot/cubietruck/u-boot-sunxi-with-spl.bin as well as this boot.scr (also from yesterday): http://os.archlinuxarm.org/os/sunxi/boot/cubietruck/boot.scr. I don't know how to find out the exact version using command line. If you tell me how to do this I happily will provide this information.

 

Regarding Cubeez: I can't boot it right now because currently I have no physical access to remove the SD-card for NAND booting. But if you give me the commands you'd like me to run to gather the information I can do this tonight.

Regarding serial console log: unfortunately I don't own a adapter to read the serial console.
