OPi zero usb deny boot and instability

Recommended Posts

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.

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.
