Hello,

 

I use armbian latest version on a Orange Pi Zero (256Mb) to send data from usb to network.

I use Ser2net for this to stream data from a rflink device.

To test I use a Metrix bench power supply, so i think power is ok.

If I reboot the device with usb plugged the boot fail, so i have to boot without usb plugged and then plug usb and restart ser2net daemon to make it work.

I think boot is searching for usb device, is it possible to disable this ?

 

Next the board crash every 2 or 3 days, network stop responding and soc heatsink goes hot.

I restart the device and it's good for 2 or 3 days, and crash...

If it help armbianmonitor -u gives : http://ix.io/1nxB

 

If anyone has an idea ?

Try blacklisting wireless (xradio) and set lower max CPU frequency (/etc/default/cpufrequtils). Some revisions of this board have overheating issues ... which are a possible cause for troubles.

Where does it hang?

I've lowered frequency to 800Mhz (don't need so much power).

 

Can i find where usb hang without screen ?

Is there a guide to disable xradio ?

There are many ways, but the simpliest is to rename kernel driver so it won't be loaded ...

Do this search to find out where it is :

find /lib/modules/ -name "xradio_wlan.ko"

Then rename it as xradio_wlan.ko-ORIG and reboot ...

Thanks martinayotte,

 

So I've reflashed my sdcard (fs was corrupted after to many reboot i think)

 

I've disable xradio, lowered cpufreq to 600Mhz, installed ser2net and armbian monitor.

 

Boot was succesfull with usb, soc temp is at 29°C (if sensor is accurate )

 

I just have to wait some days

 

The card has crashed yesterday at 17h50 (19h50 for me)

 

I've checked the log :http://ix.io/1oS9

 

It seems that the card il rebooting the morning at the same hour, the 9 and 10 October.

Armbian monitor give me a peek temp of the soc at 37°C so I dont think this is the problem (the attached file)

 

I have a serial to usb to check the card without network, that was crash, I have to disconnect it from the card and the computer in order to make it work again.

 

I've order I new sdcard to check if this is the problem.
