UDOO frozen

Hi,

Recently, I bought udoo quad and I install ubuntu 12.04 current version.
My udoo get frozen after put it there overnight.

My udoo is running
1.Tomcat ( Tomcat installed, startup, nothing else)
2. Arduino keep on post serial.println("something")

This issue happen several times, sometimes, I just open chrome and browse several web page. It hang there.
Mouse , Keyboard not moving.

Also I notice this board, the pin on board is not align very well, some part looks like hand made not machine made.

Is there anything I can do to prevent udoo frozen? Is that possible that udoo can not pass overnight test? heat, hardware....?

 

Run a top on it with your normal workload. Wondering if it's running 100% cpu and if it's overheating?

 

Hi, when it's frozen, I can't monitor it. Everything is frozen.
I think this time, I might monitor the top CPU load before it's frozen.

overheat... How do I know if the udoo is overheat or not?
I can feel the temperature of black iron above CPU.
Well...this give me a hint...probably, I may find some tool to monitor the temperature of CPU also.

 

While debugging, try also to read the serial output and check what you get.

 

Hi,

After run a while, I did not encounter the issue that I previous meet. ( 12 hour running)

I think the overheat maybe be the problem. (Previously, I use chrome for a while and frozen, this time I do not encounter such case)

1.This time I use chrome, open facebook, yahoo.com, ebay.
2.serial print
3.java program listen to serial print
4.tomcat

The system run at least 6 hour , it seems ok. But when I check the iron above CPU.
I think it's a little bit overheat. It's a little bit stress test I think. I am worry about damage this udoo board.

I think I will use the normal case to see if the overheat really a problem.(seial print, java listen to serial port only,remote desktop)

 

I ask about running top so we can see if it's banging on all 4 cores at 100% non-stop or not... If it is, that's not a good thing.

 

No, it's not 100% when I run udoo in normal status. The process is around 20~70%.

Today, my udoo frozen again, I don't have chance to see the last minutes 'top'.
I am not sure if it's running at 100% on all 4 core in last minutes.

I can't see the last minutes top because the ubuntu will blue my screen when I away.
When I come back, it stay in blue screen and no matter what I do, it won't come back.(keyboard, mouse ,remote access)

What should I do ? Try another os? debian?

I am not sure if the arduino code affect udoo part, it's simply a no delay serial print . The serial print is correct before I away.

 

did you try the previous recomendation of collecting data from the serial interface? it can be helpful during debugging.

Also im not sure just load/overheating would cause it to freeze, during my extensive temp testing i ran both the UDOO dual and quad at 100% for extended periods of time for the purposes of testing.

Additionally, you have noted a few times that there are various applications also running.
I would think, to try the common activities on a clean Official Ubuntu image, and yes, even the same on the debian release. my guess is that its software related, and not bad hardware, but this will prove that either way

 

Hi, the serial monitor print the data as I expected. It always print 'test' and I log that in file.
It's no problem.

This time I use debian and capture the issue in the terminal

It says ' kernel panic'. All I do is install debian and install arduino .

debian has nothing except browser and arduino IDE install. The arduino code already upload to the sample code with serial.print line added.


debian seems not work for me, I will try Ubuntu Studio 12.04 armHF to see if this board work better....

 

Hi,
I try to get another udoo board.
The other board working fine, ubuntu works without frozen problem.
I think this is hardware problem.
What can I do to this broken board?
