C2 freezing after 15 mins

Unread postby Strykar » Wed Apr 04, 2018 8:28 am

I have a new Odroid C2 that keeps hanging and becoming unresponsive irrespective of the OS, currently tried the official Ubuntu LTS image and it just froze again... resetting it will work, for about 15 mins
I thought it was heat at first, but the CPU reported 42 degrees C just a minute before freezing

The one thing I have not tried is powering via a 5V/2A DC jack.
I'm out of ideas on what to try next, happy to hear suggestions.

Here's a log post freezing: https://pastebin.com/pV1L8Vfb

Try this latest image.
https://wiki.odroid.com/odroid-c2/os_images/ubuntu/v2.4

42°C should not cause the freezing issue.
My CPU temperature is near 70°C now with some heavy tasks.

Which power supply do you use? It must have very stable 5 Volt output at 2Amp load.

Yea I thought the temps were fine too.
It's currently powered via USB a port that can do 5V2A, I'll try a phone charger that I know can defo do 2A and try.

Keep in mind there are no devices attached.

The factory Ubuntu image installs fine, when I apt-get update and upgrade, it goes till here and freezes:

Which SD card do you use?
Where did you buy C2?

Strontium 16GB UHS-1 SD card but it's not booting off SD.
Odroid C2 + 16 GB eMMC bought from http://www.fabtolab.com in India.

I just tried a fresh factory LTS image with a charger capable of 5V 3A and apt-get update upgrade went a lot further but still freezes towards the end:

Try other UHS-1 compatible SD card if possible.

Do you have a DMM to measure the voltage level on 40pin header 5V rail?
It must be stable at 4.8Volt at least.

I'm not sure how changing the SD card will fix anything, it's NOT booting off the SD card.
The OS is installed to and boots off the eMMC. I do not have a spare eMMC to test.

Pins 2 and 4 provide 5V, I just tested with a DMM.

I meant you might need other SD card to boot the board.
It is not related to the freezing issue.

If the voltage is always higher than 4.80 volt in the full booting process, your power supply should not be a root cause.
In that case, your board might have a hardware problem.
Please contact your local distributor for a RMA process with a link of this thread.
Sorry for the inconvenience caused.

Thanks, I did try installing to an SD card and the issue persists.
Pins 2 and 4 provide 4.8V when booting, discussed with the vendor who asked to mail the C2 in so they can work on replacement with you.

I will do another test for voltage on pins 2 and 4 before I RMA.
Thanks for the prompt response.

Tried again with a 5V/3.1A charger, the issue persists.
I could only test a 2.1A draw on my cell phone but the charger definitely manages 2A no problem.

Shipping back to vendor.

Sent board back to vendor who has shipped it to you today.
They told me a replacement will take three weeks.

Well noted.
Once we receive it, we will test the board carefully.

Can you tell me the name of the distributor?

We have no notice from "fabtolab" yet.
Did you hear they already sent the board to us?
Or they test it by themselves first?

Has the board reached? I'm not sure if it'll be from Fabtolab, but should be from India.

We received it.
But it didn't boot at all. We think some portion of the CPU or power circuit seems to be damaged by uncertain electrical damage.
Anyway, we will send a new board to the distributor today as a replacement.

Weird, you can see my logs above of it booting fine and freezing after a few mins.
Glad to hear a replacement is on the way, any chance you can test the replacement before shipping so we can avoid having to do this again?

Also, is there a way to track the board you ship, like is there a serial number so I can confirm it's the same board you sent?
I find the replacement being sent to you not via the vendor I bought it from a bit shady.

Received replacement board two days ago, this one was in a sealed pack.
Ran cpuburn on all 4 cores for 2 hours straight.
SoC rebooted once, so I re-ran the same test
It then stayed stable for the second test again at 72C with the factory case top cover off.
Test repeated once again with the same results. Woo hoo, stable C2.

It also appeared to reboot when I disconnected the ethernet cable till some folks on IRC suggested I use the DC plug.
I bought the DC to USB adapter and everything looks great! The reboot was the power jack not pushed all the way in.
Thanks for your prompt service Hardkernel.

Glad to hear you have a stable system now.

BTW, don't forget to remove the J1 jumper if you use the DC barrel jack instead of micro-USB for the power source.

It will reduce the CPU temperature obviously.
